- Bugscope Team 8.2
- 6:49am
- Bugscope Team 3.0
- Bugscope Team 2.5
- 6:55am
- Bugscope Team 2.0
- Bugscope Team magic number is 1.3
- Bugscope Team 1.8
- 7:04am
- Bugscope Team ~
- Bugscope Team 1.6 x 10-4
- Bugscope Team good morning, Grasshopper
- Bugscope Team vacuum is hovering now, looks like a solid 1.5
- Bugscope Team welcome to bugscope!
- Bugscope Team Good morning!
- Bugscope Team bugs are beautiful, indeed!
- Teacher Good Morning! We are busy getting ready for our session!! Great feedback from the last session!! What an amazing opportunity for students!
- Bugscope Team Good morning
- Bugscope Team :)
- 7:09am
- Bugscope Team we have a juicy yellowjacket in the 'scope, and it is taking a little while for the 'scope to pump down
- Bugscope Team once we have the scope pumped down, we'll make presets. we'll be ready for your session at 8AM, no problemo.
- Bugscope Team vacuum is 1.5 x 10-4 mBar, and we are going for 1.3...
- 7:17am
- Bugscope Team vac okay!
- Bugscope Team starting presets now
- 7:24am
- 7:29am
- Bugscope Team :-X
- 7:36am
- Student We have signed in some students as guests however some computers enter them as students. Does it matter?
- Bugscope Team it doesn't matter so much, they will function the same
- Bugscope Team we do prefer that students log in as students, but if they are already on as guest, it's no biggie
- Student cool
- 7:42am
- 7:47am
- Student hello
- Bugscope Team hello cicada!
- Bugscope Team welcome to bugscope
- Student hi tommy!
- Bugscope Team we are still setting up the presets for today's session
- Bugscope Team we start in 13 minutes, yes?
- Student ew this is gross
- Student i am dayna
- Bugscope Team gross, but cool
- Student hi
- Bugscope Team well, the yellowjack let out some gas, and that has temporarily disturbed the vacuum, we are getting it back now
- Bugscope Team so now you have a lovely view of the inside of the vacuum chamber while we wait for the vacuum to recover
- Bugscope Team 1.4
- 7:52am
- Bugscope Team this is the sample we have been working on this morning
- Bugscope Team you can see at the top where the electrons come from
- Bugscope Team the secondary electron detector is to the right, top
- Bugscope Team the insects are all on the stub in the low middle of the view here
- Bugscope Team we are looking toward the stage door
- Bugscope Team cool, the vacuum is back, and scott just turned on the secondary electron detector
- Bugscope Team yay, we've got high mag back!
- Teacher Cool! We will begin in about 5 to 10 minutes!!
- 7:57am
- Student v
- Bugscope Team ok, we will be ready
- Bugscope Team ok, presets are done, i just unlocked the session, we are ready anytime
- Bugscope Team you should see controls on the right side: magnify, navigation, focus, adjust, and the presets below that
- Bugscope Team if your image ever goes black, try refreshing your browser: F5
- Student t
- Bugscope Team You have control now...
- Bugscope Team there is a beetle to the right that we did not make a preset of, have not looked at
- Bugscope Team this wasp must have got mooshed
- 8:03am
- Bugscope Team there it is -- I just moved to it
- Bugscope Team the true bug
- Teacher Are there presets for an ant, cricket, and fly?
- Bugscope Team I am sorry we do not have those today. We have a grasshopper, a wasp (related to ants), and fruit flies, which are diptera (flies)
- Bugscope Team I would have put an ant on if I had one
- Teacher We had the ant, cricket and fly at our last session is there any way to show any of those
- Student no
- Bugscope Team no there is not I am sorry--this is live imaging
- Bugscope Team sometimes we run out of ants, and flies, particularly
- 8:08am
- Bugscope Team but there are plenty of other REALLY cool things to look at on this sample
- Bugscope Team And a Fruit fly is similar to a House fly
- Bugscope Team and a yellow-jacket kinda looks like an ant head in some ways
- Bugscope Team hey!
- Student hi
- Bugscope Team click once to start moving, then click again to stop
- Bugscope Team there IS a fly!
- Guest hi
- Guest ant;yo men
- Student Hi
- Bugscope Team just
- Bugscope Team hi chrysalis and june bug, welcome to bugscope! hi hornet
- Guest yo
- Guest hey junebug
- Guest we rock
- Student i likemountain dew
- Bugscope Team and or roll!
- Guest how do lady bugs have spots
- Guest why do thhey have spots
Bugscope Team i'm not sure exactly, but it might help with recognizing other ladybugs, or other species would recognize the ladybug, like cats don't like the taste of them so cats might learn not to eat something that was red with black spots
- Student hi
- Student thats cool
- Guest yo yoyo yo yo dude abbeyrox yo
- 8:13am
- Student Elise likes Barski
- Guest yo
- Guest hey
- Guest why do they like eachother
- Guest what are those pointie things
Bugscope Team setea...little hairs to help fly navigate
- Bugscope Team those pointy things are called setae (see-tee)
- Guest dilan is in love with bri
- Bugscope Team Bugs Are Beautiful did you see that you had found a fly on the stub?
- Bugscope Team setae help insects to sense their environment, kinda like cat whiskers
- Guest YO
Bugscope Team yeah?
- Bugscope Team this is the head of the yellowjacket
- Guest How do dragonflys comunicate?
- Student whats up!
- Guest it looks like a big fat head
- Student how big is a stinger
Bugscope Team well, it's very small, there is a scale bar in the lower left of the image
- Bugscope Team you can see that its eye wraps around that patch of 'hair'
- Bugscope Team these are its mouthparts
- Student why do redants bite
- Guest is that hair in the mouth
- Student wheres the tounge?
- Student what is it
- Bugscope Team it is hard to tell what is what -- the mouthparts are soft and shrivel when they dry
- Bugscope Team this is a claw
- Guest ding dong
- Bugscope Team insects have claws to help them manipulate their environment
- Bugscope Team this is the claw of one of the true bugs (hemiptera) we have in the 'scope today
- Guest ow many legs do lady bugs have 6 4 how many spots do lady bbugs have why do they have them are they inportant why
Bugscope Team they have six legs, and the number and pattern of spots varies -- the spots are programmed into the genetic code
- Bugscope Team here this is cool
- Bugscope Team see the two big compound eyes on either side of the head?
- Guest how many eyes does it have
Bugscope Team this has two large compound eyes, although some insects have simple eyes in addition to two compound eyes
- Student 1000
- Guest why do ladybugs flyy
- Student how are redants deffrent then black ants
Bugscope Team mostly, I think, the color, and the species -- there are thousands of species of ant
- Student are all of the little squares eyes
Bugscope Team yep, they are the individual facets of the compound eye, called ommatidia
- Bugscope Team each compound eye is made up of hundreds of individual facets, those bump things
- Guest what is a carnica
- Guest what is the cornicle.
- Guest whats a cornacal
- 8:19am
- Guest whats a cornicle
- Guest it sounds like corn
- Guest HI BRYCE
- Guest a part of the bug
- Bugscope Team the cornicle are like pores
- Teacher What is a cornacle
Bugscope Team cornicles also exude droplets of a quick-hardening defensive fluid called cornicle wax
- Bugscope Team the cornicle is an organ on the back of the aphid that produces dew, although not always
- Bugscope Team cornicles are found on ahips
- Student 1
- Student what is it
- Guest how many spouts does a ladybug have
Bugscope Team it varies
- Guest 2
- Student why are red ants small
Bugscope Team some red ants are small and some are not; ants of the same colony can vary widely in size depending on what they do
- Guest How much times can yellow jackets sting before they die?
Bugscope Team it depends, often they can sting more than once, but sometimes the stinger can get stuck
- Guest bye
- Guest what
- Guest how do they eat yoy yoy yoy ooy oy
Bugscope Team they have a little pointy proboscis that they can stick into leaves -- so they can drink the sap
- Guest ding dong
- Bugscope Team so sometimes they feed ants that way, and sometimes they stop ants dead using that organ
- Student bye
- Bugscope Team Bugs Are Beautiful let's go find the fly and make it into a preset
- Teacher We are just switching groups - give us a minute. Thanks!
- Teacher OK-ready!
- Bugscope Team ok!
- 8:24am
- Bugscope Team cool, here is the fly, we are making a preset
- Bugscope Team ok, we are good, we've got a fly head preset!
- Bugscope Team fly head is preset #22
- Guest dgf
- Bugscope Team fly's have great vision, with their two huge compound eyes
- Bugscope Team the fly compound eye is made up of thousands of individual facets, called ommatidia, each one has a lens in it
- 8:29am
- Bugscope Team to the left is the fly proboscis
- Guest graet
- Bugscope Team now you are getting a close-up of the exoskeleton near the proboscis
- Bugscope Team the mouthparts are to the left
- Guest what are we looking at
- Guest cool
- Bugscope Team This is the face of a fly, up close
- Bugscope Team not too much to see right here
- Bugscope Team this fly has sponging mouthparts
- Guest whats this?
- Teacher Can you tell us a little about a wasp wing?
- Bugscope Team it spits digestive juices on its food and then sucks the dissolved food up
- Bugscope Team the wasp wing is on the bottom, here, and you could see those little hooks, called hamuli
- Bugscope Team you can see them now
- Bugscope Team well, those tiny little hairs on the wing are though to help balance the wing in flight by creating more surface that is exposed to air
- Bugscope Team wasps and bees have four wings, but when they fly it is much more efficient to have only two wings
- Teacher thanks! Now-dragonfly head
- Guest whats this
- Bugscope Team so the wasp hooks its fore-and hindwings together using those little hooks we saw
- Bugscope Team the dragonfly head is what we are looking at now
- Bugscope Team this is the underside of the head of a small dragonfly
- Guest hats this
- Student wow what is that
- Guest WHAT IS THIS
- Bugscope Team dragonflies have four wings as well, but they use them withouth hooking them together
- Bugscope Team DRAGONFLY HEA
- Student What are we looking at?
- Bugscope Team HEAD
- Bugscope Team now this is a compound eye
- Guest wow
- Guest what is that
- Guest this is coooooool
- 8:35am
- Bugscope Team compound eye, with setae inbetween
- Bugscope Team the dragonfly has huge eyes
- Bugscope Team this is a yellowjacket tongue
- Guest OK
- Guest so cool
- Guest wow
- Student holy cow
- Guest bye
- Guest so
- Guest cool
- Bugscope Team good bye
- Guest thanks
- Bugscope Team mouthparts are often confusing to us
- Teacher Hi we're switching groups again
- Bugscope Team ok, no problemo
- Bugscope Team it is hard for us to realize how they work; they don't relate to the way our mouths work
- Teacher Our next group is here.
- Bugscope Team welcome to bugscope!
- Bugscope Team this is the mouth of a yellowjackets
- Bugscope Team this is a tongue of a yellow-jacket
- Bugscope Team jacket, sorry
- Bugscope Team q pr
- Guest yo
- Guest slim shady in
- Bugscope Team yo Ant
- Guest hey brother
- Bugscope Team this is just below the jaw of the yellowjacket
- Bugscope Team it's kind of like a tongue
- 8:40am
- Bugscope Team very much like the tongue of a bee
- Guest yo man you like bills
- Bugscope Team bills?
- Bugscope Team the fly!
- Bugscope Team this is a fly head
- Bugscope Team you can see its antennae at the top of its head
- Bugscope Team the proboscis is in the middle of the head
- Student soot
- Bugscope Team the mouthparts here are kind of shriveled -- they are soft and don'
- Bugscope Team t dry well
- Bugscope Team this is the compound eye of a fruit fly
- Bugscope Team this is a compound eye
- Student do you like baseball
Bugscope Team steroid boys
- Guest yo
- Bugscope Team if you take the mag down here you can see the rest of the head
- Guest What are those sticks
Bugscope Team setea...help fly sense its environment
- Bugscope Team those are setae
- Bugscope Team now we see more of the head, more of the eye
- Bugscope Team ah!
- Guest what i dont get it
- Student do the discco
- Guest why are there bumps
- Bugscope Team Earwig what?
- Guest no
- Guest eww
- Bugscope Team the bumps on the back of the head, to the right, are ocelli
- Bugscope Team these are live images from an electron microscope, your teacher is controlling the scope over the internet
- Bugscope Team ocelli are simple eyes
- Bugscope Team this is a claw
- Guest discusting
- Bugscope Team this is a claw from a true bug (hemiptera)
- Bugscope Team lots of insects have claws: to help them shove food into their mouths, to help them move around, etc.
- Guest ?
- 8:45am
- Guest What is it for
- Guest why is there hair
Bugscope Team to help insects sense their environment
- Bugscope Team well, it's gross, but it's cool. i'll bet you anything insects think HUMANS are gross
- Bugscope Team insects all have six legs, and most of the them have claws, sort of for the same reason we have hands
- Guest what are the sticks coming out of the head yo man
Bugscope Team the sticks on the fruit fly head were little bristles that help the fly gauge windspeed, wind direction
- Bugscope Team those hairs are called setae (see-tee)
- Guest do the claws help them climb?
Bugscope Team totally!
- Guest werid
- Student why do they have claws
Bugscope Team to help them climb, put food in their mouths, for defense, etc.
- Guest cool!
- Guest What bug is that
Bugscope Team this is a true bug; true bugs have piercing mouthparts
- Guest that is a werid bug pie man dog yo
- Guest why do bugs have dots on their eyes?
Bugscope Team the dots are individual lenses called ommatidia
- Guest strange!
- Guest how big is it?
Bugscope Team check out the scale bar in the lower right of the image
- Guest 500 feet
- Student why do they only have 1 antenna
- Guest why is there hair on the legs
- Guest what"s the little hairs
Bugscope Team the little hairs are often called 'setae,' and they help the insect feel, and taste, and sense heat/cold
- Bugscope Team having rounded eyes with many facets allows the insect to have better peripheral vision
- Bugscope Team one um = one micron
- Guest what are all those hairs for?
Bugscope Team hairs are called setae (see-tee), they help sense the environment
- Bugscope Team one micron one millionth of a meter
- Guest because there is chrysalis
- Guest i like grasshoppers
- Guest ey hop on me
- Student cool
- Guest why is there one eye and not another
Bugscope Team only one eye is showing
- Guest eddie do you think that is cool
- Bugscope Team the other eye is on the other side of the head
- Guest i hate centipedes
- Guest eww!
- Student how big is a normal head
Bugscope Team this head is about half a millimeter
- Guest what is that!!!
- Bugscope Team yeah this is a nasty dude
- Guest you own turkey
- Bugscope Team it is a centipede
- Guest is the grasshopper dead?
- Guest eww how gross!
- Bugscope Team it has big fangs
- Guest no
- Bugscope Team yes, all the insects in the scope are dead
- Bugscope Team all critters you are looking at are dead
- Guest What is the little hole?
- 8:50am
- Guest are all the pictures of dead insects?
Bugscope Team these are LIVE images, your teacher is controlling the scope. and yes, the insects are dead
- Guest because thay do!
- Guest whats the big round circle
- Guest eww
- Student how long is a grasshoppers life span
- Guest can bugs taste thingy ma boberz?
- Guest yo that was my bro
- Guest ewwwwwwwwwwwww
- Guest it's like a furry as a dog
- Bugscope Team this is a closeup of the yellowjacket antenna
- Guest what is THAT?i
- Bugscope Team this is a closeup of a yellow-jacket antenna
- Guest fly its not groos its cool
- Bugscope Team you can see that it has numerous sensory setae and placoid sensilla
- Guest what is that?
- Bugscope Team close up of antenna on yellowjacket
- Bugscope Team if you zoom out you can see more of the antenna
- Student what are the things sticking outt?
Bugscope Team those are called placoid sensilla
- Student how do bugs talk
Bugscope Team sometimes they make noises, and sometimes they speak using pheromones; sometimes they use visual cues to communicate
- Bugscope Team people obviously do not have antennae, so it is hard for us to comprehend how important they are to insects
- Guest wut r the littyo man yo pie eat cow dog pie
- Guest bye
- Guest goodbye!
- Guest it looks like a corn feild
- Student goodbye
- Bugscope Team good bye,hope you had fun and learned something!
- Bugscope Team Bye...
- Bugscope Team Bye!
- Bugscope Team Bye everybody...
- 8:57am
- Bugscope Team lol
- Bugscope Team this is a compound eye
- Bugscope Team with setae inbetween
- Bugscope Team those setae (see-tee), help the fly to sense wind speed and direction
- Bugscope Team those setae are mechanreceptors
- Bugscope Team they, as Alex said, move with respect to the wind, and that movement allows the fly to sense wind speed/direction
- Student what are the hairs?
- Bugscope Team some of the setae are busted off
- Bugscope Team those are setae
- Guest what are the hair like items on the compound eyes?
Bugscope Team setae (small mechanoreceptors) they help the fly sense the wind/airflow and help it navigate
- Guest How do the bumps in the eye help them see?
- Student why are there so much eyes
Bugscope Team the eye is curved so it can see all around. the lens's in insect eyes can't move like humans can, so they need more facets and they need those facets to be looking in different directions, thus the curved compound eye
- Guest how long are the setae?
Bugscope Team sorry if we were there again we would be able to tell by looking at the scalebar
- Student how many eyes do flys have
Bugscope Team they have two eyes (compound eyes) and each eye is composited of many omatidia
- Guest How long do insects live?
- Guest why do there eyes look like a bee hive
Bugscope Team they are that shape because it is the most efficient shape for close-packing
- Student what are the little hairs
- Guest how many eyes are there?
Bugscope Team two large compound eyes, some insects also have simple eyes
- Guest what are all the hairs for?
Bugscope Team to sense the environment
Bugscope Team to sense the environment, either mechanical or chemosensory stimuli
- Bugscope Team they also have three additional eyes on the top of their head
- Guest are the claws sharp?
- Guest how many eyes are there
- Guest Are there setae all over an insects' body?
- Guest is that the stinger?
- Student why do they look like claws
Bugscope Team they have claws to grasp things
- 9:02am
- Bugscope Team the hairs are part of the sensory system -- the exoskeleton is like a suit of armor, and insects need to be able to sense their environment through that. So they have those hairs, which are sensory setae
- Guest How long does an insect live?
- Guest what do they use claws for?
- Guest do the eyes see far
Bugscope Team it depends on the insect -- they see far enough to be able to avoid predators, and to do their own predation, if that is what they do
- Student do they use there claws for digging?
Bugscope Team sure!
- Guest do the eyes see far away
- Guest Are all bug faces different shapes?
Bugscope Team some are similar, like those of ants and wasps, which are related
- Guest It helps with sences.
- Student why do the eyes look like sponges?
- Guest What are the dots on the fly?
- Student do bugs have different faces?
- Student how do they breathe
Bugscope Team they have holes in the sides of their bodies, called spiracles, air goes into those spiracles
- Guest It breaths out its legs.
- Guest how does a grass hopper breath?
Bugscope Team it breathes through spiraclces
- Guest How long are the average antenna
Bugscope Team hm, they vary a LOT, so that's hard to say
- Bugscope Team spiracles, sorry
- Bugscope Team this is the head of the centipede
- Bugscope Team the antennae are missing but you can see the fangs and the eyes
- Student how big is a yellowjacket hive?
- Guest How many legs does a centipede have?
Bugscope Team They may have as little as 30 or as many as 200
- Student why do eyes look wered?
Bugscope Team they have multiple facets (ommatidia) that help them see better peripherally as well as sensing movement very quickly -- the multiple facets give them quick updates
- Guest what are the claws used for?
Bugscope Team scoop food, grab things, defense, etc.
- Guest how many spiriclces are there?
- Guest what do flys eat?
Bugscope Team they eat different things depending on what kind of fly they are; some drink blood and have slashing mouthparts
- Guest bye!!
- Guest Why do bugs' mandables opens horizantally and not the other way
Bugscope Team probably has to do with their size and the relatively lesser complexity of their structure
- 9:07am
- Teacher Would you happen to have a preset showing a spiracle?
Bugscope Team number 13
- Bugscope Team preset #13 has a spiracle on it!
- Bugscope Team if their mouths opened vertically they might not be able to see over them, for example
- Bugscope Team ha, good point scott
- Bugscope Team I think it would be much more complex structure were the mouth to open vertically
- Bugscope Team there is a spiracle in preset no. 13; let us know if that does not work for some reason
- Bugscope Team the spiracle is next to the haltere on the fruit fly body
- Bugscope Team here's the spiracle, in the upper right
- Bugscope Team this is a fruit fly haltere, and to the right, as Alex says...
- Bugscope Team in the middle is the haltere, found on all fly's
- 9:12am
- Bugscope Team this is the base of the haltere, and the rest is to the south
- Bugscope Team this is the wing
- Bugscope Team the edge of the wing
- Bugscope Team notice how many setae insects have, tons of them!
- Bugscope Team with the thorax in the background to the right
- Bugscope Team that is a good thing for insects because they use setae to sense their environment
- Bugscope Team this is a fly head
- Bugscope Team the microsetae we see probably help the insect catch air -- they give it more surface area
- Bugscope Team look at the cute little antennae!
- Bugscope Team oops now we are on the fruit fly compound eye
- Bugscope Team you can see where lots of the setae snapped off
- Bugscope Team those bumps are called ommatidia, each one has a lens in it
- Bugscope Team a fly has great vision
- Bugscope Team that's why it can fly away from you as you try to swat it
- Bugscope Team they have a sort of hexagonal shape because it is one of the best shapes for closepacking
- Bugscope Team it also can feel wind coming at it via its setae
- Bugscope Team yay!
- Bugscope Team this is a wasp head
- Bugscope Team this is cool -- the head of a wasp, with antennae intact
- Guest this is awesome
- Student yo peps
- Bugscope Team this is the mouth
- Bugscope Team yo walkingstick
- 9:17am
- Student dylan is that you
- Bugscope Team this is the compound eye, but there is some kind of film on it that won't let us see very well here
- Guest hello peeps
- Bugscope Team okay this is the fruit fly eye again
- Bugscope Team you can see microsetae in the background
- Guest that is hairy
Bugscope Team yep, insects have lots of hairs (setae), to help them sense their environment
- Student hay this is riley this si awesome
- Bugscope Team these are live images from an electron microscope, your teacher is controlling the scope over the internet
- Student this is gross
- Student no
- Guest spider is me, dylan
- Bugscope Team the microsetae are part of the vestiture -- the clothing of the head
- Student hi delaney
- Student hi
- Student are you butterfly
- Student eye
- Student alex is that you
- Guest Why do they need so many bumps on there eyes
Bugscope Team the bumps are individual facets of the eye, and it is helpful to have so many to register motion very quickly
- Student yes
- Bugscope Team if you think of an insect, with its exoskelton, as wearing armor all of the time -- it needs to be able to feel its environment through that armor
- Student delaneytell alex i said hi
- Guest doesevery bug have hair on thier eyes?
Bugscope Team no not all of them; most don't
- Bugscope Team so it has lots of setae, which are sensory
- Guest how many eyes do the flys have
Bugscope Team they have, usually, two compound eyes, and three ocelli -- simple eyes
- Student yo yo
- Guest thats weerd
- Student where is the head
- Student no they dont spencer
- Guest can a bug live without c.t.
- Student yo
- Guest awesome
- Student how many eyes does a wasp have?
Bugscope Team two big compound eyes are least, and maybe some smaller eyes on top of its head too?
- Student yo alex dog its riley
- Guest hi i
- Student 2 eyes Brandon!
- Student how do they pickup stuff?
Bugscope Team with claws, or their proboscis, or their jaws, whatever works
- Student Why are wasp claws pointed?
Bugscope Team they are curved and pointed so they can grasp things
- Student yes
- Student YYYYYYOOOOOOOOoyo
- Student do insects have a toungh
Bugscope Team yes sometimes they do
- 9:22am
- Guest sweet
- Student what are the things that look like big cheeks?
Bugscope Team those are compound eyes!!!!
- Bugscope Team this is the underside of the head of a dragonfly
- Guest how big iis a bees eye?!?!
- Guest how easy can an exoskeliton break
Bugscope Team not easily for another bug to break it, but you could smash it easily
- Student eyes
- Student do bugs have big eye
- Student WWhy are insect toungs pointed?
- Student you should
- Guest bye
- Student bye bye
- Student kyhugb ygfcdvihvb 89yv8

- Guest O0KLU
- Bugscope Team Thanks, Spider
- Student hih
- Guest UR WELCOME
- Guest OK
- Guest STOP
- Student hi
- Bugscope Team Spider let us know if you have questions about the sample, about the 'scope, etc.
- Guest ;]
- Bugscope Team Hi June Bug, the sequel
- Bugscope Team this is the compound eye of a fruit fly, up close
- Student no
- Guest Z
- Guest C00L
- Bugscope Team we can see from the scale bar that the setae are about 20 microns long
- Bugscope Team the microsetae in the background may not be sensory
- Guest How dothey breath?
Bugscope Team they use their spiracles, which are pores that feed into the tracheae
- Bugscope Team bacteria -- the rodshaped ones called bacilli -- are often about 2 microns long
- Guest What are the spikes?
Bugscope Team the spikes are mechanosensory setae that allow the fruit fly to sense wind speed, wind direction
- 9:33am
- Guest thank you
- Guest How do you get the bugs?
Bugscope Team people save bugs for us and send them; these are part of a collection, mostly
- Guest they use computerized drawings
- Bugscope Team this is the base of the haltere, with a spiracle to the right
- Teacher Where is the spiracle in this preset?
Bugscope Team I just moved us to it
- Guest :]
- Bugscope Team it is like a furry cace
- Bugscope Team cave
- Teacher Thanks!!
- Bugscope Team the setae around the opening help filter out dust
- Bugscope Team this is one of the thoracic spiracles
- Bugscope Team there will be two per segment, on either side
- Guest no
- Student hi
- Student wirdo
- Student be quiet richard
- Student weirdo
- Guest haha
- Student I'll kill you
- 9:38am
- Guest hi

- Guest hey
- Guest nm
- Guest bey
- Guest cool
- Student Spider, be quiet.
- Guest y
- Student really
- Guest no
- Teacher Could you show the spiracle on this slide again
Bugscope Team this is live imaging, you know -- this is a real insect
- Guest Y should i
- Guest hi people

- Guest What does compoud mean
Bugscope Team compound in this case means that it is composed of multiple facets
- Guest Why is there a hard shell on the outside of the insects body?
Bugscope Team because they have no bones, they need the exoskeleton to hold their bodies in shape, to keep the guts in so to say
- Bugscope Team each ommatidium has a lens in it
- Guest whats the thing in the middle of the 2 eyes
Bugscope Team that is the proboscis, which is a little shriveled compared to what it looks like in life

- Guest I don't like bugs
- Guest me to
- Guest they are weird
- Student how are bugs cool
Bugscope Team they are interesting because they are a different life form from us; we get to see how they do the same things that we do, but also how they can do things we cannot; we get too see how they are adapted to the same environment we live in, but in quite a different manner

- Student fly head
- Guest How many eyes do flys have?
Bugscope Team they have two compound eyes, with may facets, and they have three simple eyes, called ocelli
- Guest Ladybug:Whats up
- Bugscope Team insects have constraints on their size, because of the way their bodies work; if they were too big they could not breathe efficiently, for example
- Guest hello
- Guest I am spaghetti(amanda)
- Guest Whats going on
Bugscope Team these are live images from an electron microscope that your teacher is controlling
- Bugscope Team this is a compound eye, those bumps are facets, each one has a lens in it
- Bugscope Team many facets
- Student hey
- Guest does the hair hurt them on there eyes?
Bugscope Team nope, it helps to keep the eye clean, and also senses wind
Bugscope Team no it is part of their sensory system
- Guest Who has hair
Bugscope Team insects have setae (see-tee) which are like sensing hairs
- Guest Who us earwig?

- Guest i wont to eat that tongue looks yummy
- Guest whats on a yellow jackets toung?
- Guest sheila/spaghetti: Who are we talking to?
- Guest Sheila/Spaghetti: who are we talking to?
- Guest vary yummy
- Teacher How do bugs see through compound eyes?
Bugscope Team each bump (ommatidia) has a lens in it, so the insect processes many hundreds of individual images into one thing that it sees
- Bugscope Team this is a fly head
- Student me
- Guest hi
- Guest SPAGHETTI ROCKS!!!!
- Student hi
- Student ok

- Bugscope Team the brains of flying insects are often mostly taken up by visual processing
- Guest Thanks
- Teacher Another session - spiracle please:)
- Bugscope Team insects are invertebrates, meaning that they have no backbone, but they have no bones at all
- Bugscope Team to the left we see the base of one of the halteres
- Bugscope Team fruit flies and flies (Diptera) have two wings, and they also have halteres to balance the motion of those wings
- 10:57am
- Bugscope Team bees and wasps have four wings, as do dragonflies
- Bugscope Team when bees and wasps fly, they clip the fore- and hindwings together
- Teacher Can you pull up the spiracle again
- Bugscope Team so essentially they are using two wings
- Bugscope Team this is the spiracle, right on it
- Bugscope Team can you see it?
- Bugscope Team if your image is black, try refresh (F5)
- Bugscope Team hit refresh if you are not getting an image
- Teacher It is not the same image as we have been looking at
- Bugscope Team what do you see?
- Bugscope Team try refresh, F5
- Bugscope Team we are seeing the spiracle
- Bugscope Team the haltere is to the left and the spiracle is in the center
- Bugscope Team maybe your browser just needs a refresh
- Teacher We are set
- Bugscope Team this is the fruit fly compound eye
- 11:02am
- Bugscope Team you can see the individual facets of the eye here
- Bugscope Team this is the head of a waps
- Bugscope Team wasp
- Bugscope Team this is a claw of a true bug

- Teacher Thanks for the tip about the refresh - it worked. We have another class - spiracle again:)
- Bugscope Team this is the antenna of the yellowjacket
- Bugscope Team who is driving?
- Bugscope Team i was trying to go to the spricale
- 11:07am
- Bugscope Team but i'm not driving anymore
- Bugscope Team we are having trouble getting to the spiracle
- Bugscope Team this is the assassin bug!
- Teacher They are not here yet so we have a couple of minutes
- Bugscope Team welcome to bugscope

- Guest eye
- Bugscope Team this is one of the compound eyes of a fruit fly, one of the fruit flies on today's stuv
- Bugscope Team stub
- Guest got it
- Bugscope Team on fruit flies, unlike most other flies, there are setae in between the facets of the eye
- Bugscope Team the facets are called ommatidia, and each is like a small lens
- Bugscope Team this is a wasp--see its compound eyes?
- Bugscope Team they are like wraparoudn sunglasses
- Guest "ommatidia"
- Bugscope Team wraparound
- Bugscope Team right, and singular is ommatidium
- Guest cool!
- Guest claw?
- Bugscope Team this is one of the claws of a true bug, which is, for example, what a stinkbug is
- Bugscope Team claws are used to scoop food, grab onto things, defense, etc.
- Bugscope Team you can tell from looking that it is not likely this bug could crawl on the ceiling
- Guest what do bugs use the hair for
Bugscope Team the hairs are called setae (see-tee), the sense the environment around the bug. some setae are mechanosensory others are chemosensory
- Guest looks like it scot
- Bugscope Team but it may still have a sticky pad on its tarsi that helps it cling to surfaces
- Guest whats this
- Bugscope Team this is the tongue apparatus on a yellowjacket, which is a kind of wasp
- 11:22am
- Guest "mechanosensory"
- Bugscope Team actually the tongue here resembles the pulvillus on an insect that can stick to the ceiling
- Guest "chemosensory"
- Bugscope Team the pulvillus is a pad with tiny tenent setae on it
- Guest do any ants spin a chrysalis?
- Guest what do those words mean

- Guest how big do they et
Bugscope Team the proboscis?
- Teacher Another session - spiracle again:)
- Bugscope Team think of what it would be like if you walked around all day in a suit of armor
- Guest tHE WHOLE BODY
- Bugscope Team ah, let's go to another spiracle, this is a new one, a better look inside too!
- Bugscope Team if you had a suit of armor you would not be able to feel things touch you
- Bugscope Team this is a spiracle, a breathing hole on an insect, in this case a dragonfly
- Guest OpI had the caps lock on-sorry
- Bugscope Team but if you had little hairs (setae) sticking through your armor, then when they moved or were touched you could feel it
- Guest I am spelling things wrong
- Guest why am I doing that
- 11:28am
- Bugscope Team setae can be mechanosensory (touch-sensing), chemosensory (smell or scent-sensing), and/or thermosensory (hot/cold sensing)
- Guest think I got it,scot
- Bugscope Team this is one of the breathing pores (spiracles) in the thorax of a dragonfly -- so this is how the dragonfly breathes
- Bugscope Team Aditi we have a group of students watching who have not seen this before, and if you want to help it is good if you know this stuff as well.
- Guest What is the world's largest insect?

- Guest WHAT IS THAT?????
- Bugscope Team the spiracles lead inside the exoskeleton to tracheae
- Guest what is this.
- Guest what is that thing in the middle ya'll
Bugscope Team that is the proboscis
- Bugscope Team this is a fly head
- Guest What is that?
- Bugscope Team the compound eyes are on the side, the antennae on top, and in the middle is the proboscis (that's what it uses to suck up food)
- Student what is eyes called yall
Bugscope Team these eyes are called compound eyes
- Bugscope Team unfortunately the proboscis is shriveled
- Guest how many types of flies are there
- Guest idk
- 11:33am
- Bugscope Team some eyes are compound eyes, like this, and some are simple eyes, called ocelli
- Bugscope Team singular of ocelli is ocellu

- Bugscope Team I would like to see if the wasp has a visible stinger
- Bugscope Team oh well
- Bugscope Team it looks like a rabbit
- Bugscope Team the 'ears' are its antennae
- Bugscope Team you can see its eyes, on either side of the head
- Bugscope Team the compound eyes are composed of thousands of ommatidia -- the facets of the eye
- Bugscope Team and here we see a fruit fly's compound eye, up close so we see only a few ommatidia
- Bugscope Team the fruit fly eye is different; it has little setae that help it gauge windspeed/wind direction
- Bugscope Team and that was a wasp
- Bugscope Team this is the claw of a true bug
- 11:49am
- Bugscope Team if we take the mag down here we can see what the bug looks like
- Bugscope Team the claw closes and opens when the insect uses a tendon inside the forearm (tarsus) called an unguitractor.
- Bugscope Team it's like one of those claws you can buy to extend your reach
- Bugscope Team this is the tongue of a yellowjacket
- Bugscope Team this is the mouth of a yellowjacket, and you can see sticky pads on the tongue
- Bugscope Team the tongue is folded back onto itself, so it looks curvy
- Bugscope Team those tiny hairs are what it uses to drink your Coke if you spill it at a picnice
- Bugscope Team picnic

- Guest why are there hairs on grasshoppers
Bugscope Team those hairs are called setae, and they are on all insects. they help insects to sense their environment
- Guest how many eyes are on a fly?
Bugscope Team a fly has at least two large compound eyes, and some might have other simple eyes

- Student why do bugs have spiracles?
- Guest what do praying mantis eyes look like
- Guest why are dragonflies eyes so wide
- Student how do bugs chew if theydon't have teeth?
Bugscope Team well, some don't even chew, they just slurp. the fly for example, slurps up it's dinner into its proboscis, like using a straw
- Guest Why do some insects have to have hairs on them?
Bugscope Team so they can feel their environment

- Student do catch insects and keep them?
Bugscope Team we don't keep insects for long
- Student what is the most dangorus bug??
