Teacher Hi. Had big meeting just got out and class starting. Kids will be on in 5 mins
Bugscope Team hello!
Bugscope Team Welcome back to Bugscope!
Bugscope Team Hi!
Bugscope Team Hi Joe!

Bugscope Team Hey Scott!
5:07pm
Bugscope Team couple more things to find...

Teacher OK, finally in the library and kids coming in. Facilities didn't set up tables so running around doing that

Bugscope Team it's no problem, take your time.

Bugscope Team Hello Henry!
5:13pm
Student Hello!
Student Hello
Bugscope Team Hi!
Bugscope Team Hello Everyone!
Bugscope Team Please let us know when you have questions, about anything...
Student Yes Sir!
Bugscope Team this is a closeup of the grasshopper's compound eye
Bugscope Team the little hexagons we see are the ommatidia
Student Cool!
Student Hi
Bugscope Team Hi Peter!
Student Hi
Bugscope Team Hello Heecheol Moon!
Student lol

Student Hi
Student hi
Student WHat are those flakes near the hexagons?
Bugscope Team maybe you can drive up closer to see
Bugscope Team we are not sure -- some kind of juju, dried debris
Student Mucho gusto
Student :)
Student I am Andy Lee
Bugscope Team Awesome -- nice to meet you!
Student Interesting
Student Hi!!
Student Hi
Student This is cool
Student HI
Bugscope Team these are the hornet's mandibles
Student I can't believe the bugscope could do this
Student you kidding me? of course
Student Nice to meet you too
Bugscope Team some of these critters are so big we can only see portions of them
Student This is epic
Student This is epic
Student Hi
Student Muy interesante
Student Is this the tooth?
Bugscope Team you are driving the scanning electron microscope from your school
Student What is that
Student What specifically is a mandible?
Student Look at the eyes
Student :P

Student Hi
Student why is one part sticking out?

Student It has a little far
Student How is the texture of the tooth?
Student It looks like a beak of bird :)
5:18pm
Student HI

Student Is these furs?

Student What is that?
Bugscope Team these are the grasshopper's palps and other mouthparts
Student ygub
Student Mistake
Student Why is the teeth or beak overlapping each other
Bugscope Team they always do, or almost always; they open and close like a gate
Student this looks like a brain
Student What are palls?

Student what is a palps?
Student Is that a leg?
Bugscope Team those are palps, which are used to help convey the food to the mouth and also help taste it

Student are those hair?
Bugscope Team the things that look like hair are setae

Student What is a setae?
Student Where are we?

Student What are palps?
Bugscope Team they're feelers, accessory mouthparts

Student where are we?
Bugscope Team We're near the grasshopper's mouth parts

Student What is the bumpy thing that is on the skin

Student Is that a long things like fur?
Student what are the parts of the hairs

Student Junsung..
Student oh
Student oh

Student Why are you joking about brian?
Student what\

Student yeah what is a setae
Bugscope Team a seta is a sensory hair, or sometimes it's not sensory, I guess

Student eww..

Student oh
Student the photos are blurry

Student Why it has little far in mouth?
Student Why it has little far in mouth?
Student where is the mouth?
Student how come this is mouth part?

Student its better

Student where are we now?
Bugscope Team insects do not have skin -- they have an exoskeleton that is like a shrimp shell, or like armor
Student The leg?
Student hehe
Student are these cuts??

Student we are on the antennae
Bugscope Team so they have setae that stick through the exoskeleton -- the armor -- to allow them to sense their environs
Student does seta sense the prey?

Student henry
Student does seta sense the prey?
Bugscope Team yes they do in many ways
Student What is that part?
5:23pm
Student Antennae
Student 하하
Teacher Please give Jay Lee control
Student Why are these setae so sensitive?
Bugscope Team some are chemosensory, some are thermosensory, some are mechanosensory
Student What are the furs on the antenna?
Bugscope Team the furs are the setae, these help with sensory.

Student What part does the hair do? Does it help the grasshopper?
Student are the furs there to feel things?
Bugscope Team yes they are, exactly

Student How many furs are there?

Student These setae look sharp from here

Student That is eye I think
Student Is that the eye?
Student The Circuler shape is eye?
Student Are those eyes?

Student is that the brain
Student There are a lot of eyes
Student those look like eyes on the side

Student Wow
Student What is the middle part?

Student what is the little thing sticking out of the mouth?

Student ęww
Student What is that thing insie of the mouth?

Student inside

Student Is this eye?
Student What is the little sticking things sticing out of mouht?
Student Eye has a hexagon
Student Eye has a hexagon
Student What part does the hair do? Does it help the grasshopper?
Bugscope Team Yea, some hairs, or setae, are chemosensory, for example, the ones on the palps most likely help the grasshopper taste, there are these hairs on its legs as well, and for certain species these sense when there is overcrowding, and this turns grasshoppers (usually solitary) into locusts (gregarious form).
Student Are those hairs covering the antenna part?

Student what is proprioception
Bugscope Team self sensing, like so the insect can sense when its arm is bent or hyperextended
Student why are there furs on the eye?
Student Are those the eyes..?
Student What is that?
Student the eyes has scratches

Student How many spectrums can a fly see?

Student the leg is covering the eye...

Student Why it's eyes have tessellation?
Bugscope Team that is the best way to close-pack things that are essentially round in a 3D shape
Student I think it is used for various vision

Student Why are the shapes hexagons?
Student do thoae shapes in the eyes help the insects to see things?

Student Why are the shapes on the eye hexagons?
Bugscope Team closepacking of the lenses

Student Can the hoverfly see different kinds of color?
Bugscope Team some insects see colors better than others, and some see colors that others do not see; some see in UV wavelengths, which we do not
Student What is this?

Student what are those dots or hole?
Student What is the middle part of the mouth? Is that a mouth to suck the horney?
Student I heard that they can see ultra violet is that correct?
Bugscope Team yes it is -- some insects can see UV light
Student Is that mouth?
Student what is the spider web looking thing?

Student why mouth is divided by 2 parts?

Student What does the hoverfly eat?
Student What are those in the mouth?
5:28pm
Teacher Please give Yenah control, thank you
Student What is this? Tounge?
Bugscope Team yes it is covered with juju though
Student I guess the middle thing might be the nose..
Student What is this? part?
Student What is the spider web looking thing inside the mouth?
Student Are the things in his mouth some left overs of food?
Student /ban frogandy
Student How do they eat?
Student why mouth is divided by 2 parts?
Bugscope Team it is really hard to tell, but the tongue is in the center, and there are palps on either side we do not see

Student what is this?
Student Are those thorns?
Student What is this?
Student What is mold?
Bugscope Team fungus/mold -- what comes along to help start the decaying process
Student What is this?

Student Can they taste?
Student What is that?
Student What part of the mummies?
Student What does the hoverfly eat?
Bugscope Team The hoverfly adult feeds on nectar, the larvae feed on feces, decaying materials, or other insects, depending on the species
Student mummie...
Student wowo
Student What are those things?
Bugscope Team those are mechanosensors

Student are these still hair?
Student are these still hair?
Student what are mummies?
Student are these still hair?
Student What is this mummies
Student What is mechanosensors?

Student Why are they over lapping?
Student what do these things do?
Student What is these furs do?
Student What are those things that look like hair?
Student Are these thorns?

Student what insect is this?
Bugscope Team this is the hoverfly

Student wow.. what is this part?
Student lag
Bugscope Team sorry
Student What is mechanosensors?
Bugscope Team they get feedback from the motion of the haltere
Teacher Haha SEM, can you put that in middle school language
Student Why are they so bumpy?
Student What are mummies?
Student what is bacterium?
Student Where's the mummie located?
Student What do these things do?
Student Why is the surface of these mysterious things not flat?
Student WHAT IS THIS?
Student What part is this?
Student WHAT PART OF THE MUMMIES?
Student uh...
Student How do they clean themselves?
Bugscope Team they use oral secretions, either directly applied, or using an appendage to reach where the mouth can't
Student What part is this?

Student What is this part?

Student What is this?
Student What does it do?
Bugscope Team this is part of a long, weighted shaft called the haltere that beats with a motion oppositve that of the wings
Student What is this?
Student What are these hair looking things? are they still setae??
5:33pm
Student What are these hair looking things? are they still setae??
Student Why is this so hairy while in the other hand, the other parts don't?
Student What is this part and what does fur do on this part of hoverfly?
Student Look on the upper left part of the picture!
Student Is this sort of like a bug flight sensor?
Student Does the closepacking improve the eyesights other than the other insects?
Bugscope Team The number of facets an insect have is more likely related to when an insect is active. diurnal insects (day active) usually have larger facets, where as nocturnal (night active) ones usually have tighter packed ones
Student BG DCFBHJN
Teacher Please give control to Yenah please
Bugscope Team got it!
Student S;;']\
Student ¿¿¿¿¿
Student Mistake
Student what are you doing andy
Student What is that furry thing?
Bugscope Team this is close to the fly's body, and we see lots of setae

Student What part is this?

Student Tjank you SEM!!

Student *thank*
Student What does this part of the bug do?
Student This is super cool. Thank you >
Student wow the butterfly wing scales looks cool

Student Are they holes?
Student why it has a little holes in each line?
Student Why does it have holes on the wing?

Student What are those holes?
Bugscope Team those are part of the latticework of a single scale on the wing of a butterfly

Student Are the wings woven?? like knitting??
Bugscope Team not really but they look like that, don't they?
Student Why does it has holes on the wing??
Student why does this wing have scales????
Student like bamboo...

Student What is mechanosensors?
Bugscope Team mechanosensors are just sensory units that senses movement
Student WHy does it have holes?

Student Why do we have holes on butterfly wings?
Student Christopher typed weird things with my computer. It was not me

Student Why does it have holes on the wing?????
Student why are there big holes?
Student Wing is divided by 2 parts
Student Doesn't whold distract them when they are flying?
Bugscope Team mold? they don't have mold on them while they are still alive
Student What are those things that looks like a ripped tissue?
Student What are the other uses of the scale?
Student Why does it have holes on the wing??
Bugscope Team they make the scales lighter in weight
Student why are there holes on the wing?
Student Do the scales help the butterfly when it's flying?
Teacher Oops. Yenah got disconneted. Can you give control to Lynn Kim please?
Bugscope Team Lynn Kim is now the Master

Student wow, what is this?
Student What is that thing inside the hole?
Student What are these holes?
Student What are those two things that look like airplane jets?

5:39pm
Student What are those things insdie the hole??
Student What is the part that is inside of the holes?
Student Are these thorns?

Student Why is there sharp things in the holes?

Student Oh! Those dusts were the scale!

Student How the scale works? (please answer)
Bugscope Team by falling off easily when the insects flies into a spiderweb; by refracting light in what are called structural colors; by producing pigmented colors; also by functioning much like feathers
Student what are these things that are in the hole?

Student So those are the 'powder' that get off when we touch their wings?
Bugscope Team yes it is!
Student What bug is this?
Student What bug are we looking at?

Student What is the name of this bug ??
Teacher Which bug are we on?
Student what is a sensillae?
Bugscope Team fancy term for a sensing organ

Student What bug are we looking at?
Bugscope Team you are close up on a hornet's antenna
Student What is this part?

Student Disconnected...
Bugscope Team this now is a dragonfly wing
Student what is that thing?

Student what are these sharp things?
Bugscope Team they are spines on the wing veins

Student Why is the wing so thin?
Student What is this stick on the part of the dragonfly wing?
Bugscope Team placoid means it is plate-like

Student is it a smooth surface with little bumps?
Bugscope Team yes it is
Student oh

Student Why do they have the sharp things?
Student What is the scratch?
Student Why to wings have veins? Are they like nerves to control the wing?
Student What are the lines?
Student What are the sharp things on the dragonfly wing?
Bugscope Team those are spines that probably protect it and also keep it from getting completely flattened and sticking to a wet surface
Student What are those lines on the wing?

Student Is it dragonfly wing?
Bugscope Team yes
Student Is the shapes are irregular?
Student What are those holes?Is it ripped off part?
Student What are those line of the wing?

Student this looks like a cracked leaf
Student What are those line of the wing?
Student Is that a crack on the wing?
Student Rectangle shape?
Student What are those line of the wing?

Student What are those lines on the wing?
Student What are those line of the wing?
Student Why are dragonfly wings shiny?

Student What are those line of the wing?

Student Please answer to Peter..
Student why is it smooth when butterfly wings have holes?
Bugscope Team this is a completely different type of wing; I think it is safe to say that is evolutionarily older
5:44pm
Student el mystery
Student What are the vein like things on the wing?
Student What is that scratch?
Student Please answer to Christopher.. He is really curious about these
Student Why are they hexagon?
Student who's .?

Student Why are they hexagon?

Student Is there any pattern for wings?
Student What is that hole for?
Bugscope Team what hole is that?
Bugscope Team sorry we miss some of the Q's
Bugscope Team many of the Q's

Student The Wings have scratches
Bugscope Team yes they do!
Student Why are they hexagon?
Student What are those lines on the wing?
Bugscope Team those are wing veins
Student what is the difference between the dragonfly's wing and the butterfly's wing?
Bugscope Team dragonfly wing doesn't have scales, and they are generally much more elongate going perpendicularly away from the insect's body
Bugscope Team Butterfly's wings are also hooked together so that they fly with more of a fluttering style
Bugscope Team the dragonfly is more able to control each wing than the butterfly is
Student v

Student Why are they hexagon?
Student I mean the scratch
Bugscope Team some of those are places where the wing is broken; it is very fragile

Student I think many people are asking the same questions
Student What are the lines made of?
Bugscope Team chitin
Student why are the hexagons or pentagons(?) so irregular?
Teacher No worries, Scot, I'm telling them you can't answer them all. I'm trying too :)

Student It looks like bat
Student Is it mouth part or claw of the hornet?

Student are those two wholes eyes?

Student Is there a reason that there are only two claws?
Student what are the white sharp things?
Student Can hornets bite?

Student What is the sharp thing?
Student Are those teeth?
Bugscope Team insects do not have teeth, but some of the features like the claws are hardened with calcium or zinc, for example
Student What are these two horn-looking things?
Bugscope Team those are claws

Student claws?

Student how and when do they use their claes?
Bugscope Team they use them quite like we use our hands
Student What are those fur?
Student What are those furs?

Student Do claws have a poison?
Student what are these hairy things?
Bugscope Team lots of setae
Student does every insect have fur?
Student on which body part is this ?

Teacher Please give Kate control of the scope, Scot
Bugscope Team some of the setae, or microsetae, help with thermoregulation

Student cool!

Student Are they are scales?
Bugscope Team please apologize to Yenah for me
Student Why do these hornets need claws when it can fly?
Bugscope Team the claws help them walk over different surfaces
Student Is this leg?
Student what are does scales on the antenna?
Student what is that big things looking like little fins?

Student and why don't some places don't have holes?
Student Why does it have so much hair?
Bugscope Team it has a huge variety of purposes
Student When does the butterfly use the antenna?
Student Why does it have a little kind of particles on the antehnna?
Student Is that aclaw?

Student It's sharp!

Student What are those little hexagons on the antennae?
Bugscope Team those we part of the texture of the cuticle
5:49pm

Student Does it have poison in it?
Bugscope Team not in the claws. the poison in the hornets are in the stinger, which comes out of the last segment of the abdomen (a modified ovipositor, or egg laying apparatus)

Student Thanks :D
Student What does these claw's fur do?
Bugscope Team it helps the insect tell when it is touching something

Bugscope Team when I was Scot I accidentally wiped Yenah off the map
Student What are those long pointy fur-looking things?
Bugscope Team so I am SEM again
Student why are there holes

Student Yaaaayyyy :)
Bugscope Team haha

Student Scott and Sme is same?

Student why is the claw so dry, or at least it looks like it.
Student What are those furs for?

Student Escuse me Sem, when does the grasshopper use its claws?
Bugscope Team it uses them to grasp; when it walks it holds them up out of the way; in the center of the claws is the arolium, which inflates to help hold onto things
Student Is that a joint?
Student THERE'S HAIRS ON THE BALL

Student is that a mouth?
Student Scot = Sem? Is this right?
Bugscope Team yes and also sj, but that is in my office
Student It is like a cactus....
Student What is the little bug-looking part?

Student What are the furry things? It's very hairy
Student cool they also have joints?
Student what is that big bumps?
Student Is that a joint?
Student Why so hairy?
Student what are...
Student What are those circles?
Student What is circular part?
Student What are those balls?
Student why are there bumpy things/
Bugscope Team it is a ball and socket joint
Student What are those bumps?
Student w
Student What are those bumps?
Student What are those bumps?
Student Is that eyes?
Student Is that eyes?

Student Excuse me sem, what is the little bump?

Student What are the pimple-like bumps?
Bugscope Team those are ocelli -- simple eyes that help the hornet navigate
Student what are those bumps?
Bugscope Team ocelli
Student What are the little bumps?
Bugscope Team ocelli --simple eyes
Student what are those bumps?
Bugscope Team ocelli
Student what is ocelli
Student What is ocelli?
Student oh

Student What is Ocelli?
Bugscope Team they are also called simple eyes, and there are three of them
Student So, is ocelli same as eye?
Student eye

Student What are the things on the eyes?

5:54pm
Student when the antenna breaks, does it regrow?
Student Do some of these insects only have ocellis? Or do they have other pairs of eyes which help them to see things clearly?
Student how come there are so many setae?
Bugscope Team I think they help the insect hold onto the air and also help keep its temperature -- its body temperature -- stable
Student This eye also have hexagon shape
Bugscope Team yes it does!
Student Does hornet has 5 eyes?
Student What are those dusts near to the eyes?
Teacher Please give control to Katie Lee
Bugscope Team Katie Lee is the Supreme Commander
Student was that an antena joint
Bugscope Team yup
Student why are the legs and the eyes so close together?...
Student Why do they have more than 1eye?

Student What is that?

Student pimples
Student what is that little bump?
Student what is that bubble looking thing?
Student Do hornets have more than 2 eyes
Bugscope Team they have huge compound eyes with many facets, and they also have three ocelli
Student what are those pimple looking bumps?

Student are those bumps simple eyes aas well?
Student What are those next to the hairy part?
Student What are those bumps on the bumps? Are they like air bubbles?
Student what are those lumps? (those look like eggs :D)

Student Why do they have a lot of hairs?
Student Why there are bumps on the bumps?

Student what is that bubble looking thing?
Student Is it eggs?

Student Why is there a lot of hair?
Student the bumps look like a cell

Student don't think so
Student what is that bubble looking thing?
Student What is the line for in the middle between the bumps and the fur?
Student what is that bubble looking thing?
Student Are there reasons that they have all these bumps on bumps?
Student it looks like a pimple on a pimple

Student What is ommatidia?
Bugscope Team they are the individual units that make up the compound eyes
Bugscope Team oops I should have said flies
Student Why is there bumps on bumps?
Bugscope Team that is some kind of oil, John

Student what is the difference between setae and vestiture?

Student it looks like stale bread
Student What is this? Eyes?
Bugscope Team sorry I see we are now on one of the claws, with an arolium in the center

Student why are there oils on the bumps? Why do they need it?
Student what does arolium mean?
Student What is biofilm?

Student What is arolium?
Bugscope Team it is a sort of air bag

Student what is biofilm

Student What does those furs do?
Student Are those mold?
Student a thin, slimy film of bacteria that adheres to a surface.

Student are those fur or claws?
Bugscope Team those are sensory setae, so 'fur'\
Student what is the difference between setae and vestiture?
Bugscope Team the setae form the vestiture
Student it looks like islands
Bugscope Team yes it does!
Teacher Please give control to Calvin Seo please

Student It's cool
Student what does the ommatidia do?
Bugscope Team they work together to give the insect a somewhat resolved picture of the world around them.
Bugscope Team resolution isn't great though, as in order to achieve the resolution of the human eye, the compound eye on us would have to be about 1 meter in diameter(imagine that on a human..
Student What are those sharp things?
Bugscope Team those are mechanosensory setae -- they are touch-sensitive
Student its glitching
Student What is that sharp things?
5:59pm
Bugscope Team Calvin is now the Boss of the 'scope

Student what are those things that looks like dust?
Bugscope Team Yenah they probably are dust.
Student are I mean
Student What is mandibles?
Bugscope Team that is what the jaws are called; in people, the lower jaw is the mandible and the upper jaw is the maxilla
Student we saw this before
Bugscope Team sorry; who's driving?
Student What is mandibles?
Bugscope Team they are what the jaws are called; they open side to side like a gate, not like our jaws
Student the jaw
Student why are there two calvins
Student Calvin Seo's the leader now
Bugscope Team exactically
Student wasn't this the hornet we saw before?
Bugscope Team yes it is
Student let's look at antenna segment
Student There are 4CALVINS
Teacher Calvin is but he's having trouble going to the Antennae Segment
Bugscope Team I can drive us directly to it
Student cool
Student It looks like a worm...
Student what is that worm looking thing?????
Student Why are antennae always curved when it can be straight?
Student what are these circle things?
Student Wow who's is it?
Student The holes, what are its effects?
Bugscope Team but I am sitting at the scanning electron microscope (SEM)
Student How come some places have hokes?
Student What is placoid sensillae and chemoreceptors?
Student We're near the placoid chemoreceptors?
Bugscope Team yes we are!
Student How come some places have hokes?
Student what is placoid sensillae/chemoreeceptors?
Teacher Haha. We are trying to get to the Antennae Segments. We saw the chemosensors already
Bugscope Team these are on the antennae, DaddyO

Student It also have a holes in it. Why is it?
Bugscope Team this is the moth antenna
Student what are placoid sensillae/chemoreeceptors? Jae-Minwhat is placoid sensillae/chemoreeceptors?
Student what is that particles on it?
Student what is placoid sensillae/chemoreeceptors?
Bugscope Team they are what help the insect sense things like smells in the air, or pheromones'
Student What are those things covering the antenna?
Bugscope Team scales
6:05pm
Student What are the placoid sensillae:
Bugscope Team they are plate-like sensory surfaces that may be chemoreceptors
Student Why are the scales in on the antennae
Student it is like footprint
Bugscope Team yes it is!
Student why are there lots of scales on one side, and less in the other?
Bugscope Team they were most likely surrounding it, but have since fallen off
Teacher Please give Nate Kim control
Bugscope Team got it!
Student What are those little dotts?

Student Do scales grow back again?
Bugscope Team no they do not; the insect does not molt and does not grow new scales
Student wowo

Bugscope Team this is totally cool
Student wow!
Student what is that?
Student it is like quid
Student antena?
Student This looks like jellyfish!
Student Why is that fur so long?

Student What are these jellyfish looking things?
Student It is like octopus or squid
Student what is that lines thing?
Student it looks like a jelly fish
Student this looks like the tree in avatar
Student What is the furry things?

Student antena
Student It looks like a tree.. what is this?
Student do the fur grow back?
Student It looks like a bamboo stick with hair...
Student Does this design of antennas help?
Student Why does it have long fur looking things
Student why are there strings dangling?

Teacher Which bug is this from?
Bugscope Team it was just sitting there; it is from a mosquito or something
Student why are there strings dangling?
Student why are there strings dangling?

Student what bug is this from?
Student why are there strings dangling?'

Student do the fur grow back?\

Student why are there strings dangling?
Student What is that?
Student what is this thing from?
Bugscope Team I am not sure. It is very small, someone's antennae
Student if they take out the slaughts, don't the scales grow back?

Student What is that?
Bugscope Team it is an antenna, and likely from a boy-type insect

Student Why are there cracks on the wing?

Bugscope Team oops 'can'
Student It looks little bit similar with the dragonfly's wing
Student The grasshopper wing looks a lot like the dragonfly wing?
Student A mosquito... Why does it look like it's moving?
Bugscope Team the electron beam cna affect it because it is small

Student How come some places in the wings have cracks?
Bugscope Team it's not the insect's fault; it is likely our rough handling after the insect died

6:10pm
Student What are those holes?
Student Is grasshopper's wing stronger then dragon fly's?
Bugscope Team maybe...
Student Why does it look like a leaf?
Student They look likes leaves...

Student look like cabage
Teacher Please give control to Sun Jun please
Bugscope Team got it. Kim means 'gold'

Student Is that a eye?
Student How can you identigy the female and the male?
Bugscope Team there are lots of ways, but sometimes you cannot from the outside
Student what is that hole in the middle?

Student Exact hexagon
Bugscope Team yeah Cool huh?
Student How do you identify if its a boy insect and a girl insect?
Bugscope Team they have different sexual organs. many insects, dissection is necessary. there are also sometimes sexual dimorphisms that occur so you can tell with just looking at the outside.
Student Wow

Student What are those dirts?
Bugscope Team with flies, the females' eyes are often far apart, and those of the males are close together
Student the eyes look so cool

Student yes
Student There is a hole on the bottom right. what is that?
Student why hexagons?
Student Then we have to disect the bugs to find out its gender?

Bugscope Team with moths and mosquitoes, the antennae are often more ornate on the males
Student What are small things stuck?
Student What kind of view do they see through these eyes?
Student The tessellations are so neat and located just next to each other

Student if their eyes get dirty can they clean it?

Student why hexagons?

Student so if the grasshopper dead body stays for a long time, will the wing be cracked a lot?
Bugscope Team the wings become dried and more fragile, but should stay intact unless something/someones breaks it.

Student Why all the insects has the hexagons in their eyes
Bugscope Team sometimes they are not hexagonal, but often are; it is a natural shape for something that is essentially round but close-packed in a dome shape

Student ?Why are the eyes always hexagon
Student it looks so cool
Student Why is there so many dust on eye?
Bugscope Team it's partly our fault since the insects are dead and cannot clean themselves with their arms
Student What are small things stuck on the eye? Is it dust?

Student can grubs live inside the eye
Student What is that hole?
Bugscope Team I think it is a place that looks like a hole but is actually absorbing electrons
Teacher Please give control to Chaelin Park please
Student what are dimorphism?
Bugscope Team differences between the sexes based on morphology, size, or something else
Student do those white things disturb the grasshoppers from seeing?
Student What is the hole? and the white thing?
Bugscope Team the white thing is a sensory setae that lets the insect know when wind is going by or something is touching it
6:15pm

Student Excuse me Joe, how do the bugs clean themselves?
Bugscope Team they use some type of oral secretion to clean areas their mouths can reach, and use their legs to help reach areas the mouth cannot.
Bugscope Team Chaelin should be able to drive now.

Student What are those little holes on the eyes, Joe?
Student Are bugs supposedly to be clean?
Bugscope Team yes they are. they are usually quite fastidious

Student the balance of a organ
Student What is haltere?
Bugscope Team it is a knobbed branchlike structure that beats opposite the way the wings beat (in flies) and balances that motion

Student What are those furs' functions?
Student What does haltere do?

Student how does the hoverfly use its halatrae?
Student what's a haltere?
Bugscope Team haltere is the modified second pair of wings in flies, the act as a sort of gyroscope used for balance in flight
Student Is it broken at the end?
Bugscope Team it is dried and shrunken, not like it is when the fly is alove
Student where's the haltere located?
Bugscope Team they are where the hindwings would be

Bugscope Team or you could say they are modified hindwings
Bugscope Team this is awesome
Bugscope Team yea crazy looking
Student the balancing organ of a two-winged fly
Bugscope Team exactically!
Student Are those things are setae?
Bugscope Team microsetae

Teacher Beautiful!
Bugscope Team sometimes they are also called trichae

Teacher I didn't even know about haltere before today. Amazing!

Student Why is there thorn on the line?
Student A lot of setae! Do big amounts of setae do good for the bugs?
Bugscope Team these form patterns, among other things; they may produce iridescence
6:20pm
Student What is a trichae?
Bugscope Team it is another word entomolgists use for super tiny hair-like things
Student Are there sometimes setae on the insects' wings?
Student What are iridescence?
Bugscope Team reflecting light in shiny colors
Student SEM and Scot thank you!!
Bugscope Team Thank You!
Student Thank you
Student Thank you!!
Student Thank you~
Student Thank you and bye
Student Thank you!
Student THANK YOU~~~
Student Thank you!
Student Thaaannnkksssss!
Teacher Some students are leaving but I have about 10 more minutes
Student Thank you....bye....
Student Thank you!
Student thank you ~~!!^.^
Bugscope Team Joe is an entomologist, so he keeps me in line.
Student Thank you so much! :)
Student Bye~!!!
Bugscope Team Thanks1 bye!
Teacher Please give me control
Bugscope Team got it DaddyO
Student Thank you! I got to learn more about bugs :D Bye!
Bugscope Team Bye Sue!
Teacher I want to snap a few more pics for our collection

Bugscope Team Thank You, Everyone!

Student thank you
Bugscope Team Thank You, John!

Bugscope Team you can see the retention plan

Bugscope Team the big spines on those raptorial forelimbs

Bugscope Team this is the arolium, in the center
Bugscope Team it puffs up and helps the insect hold onto crevices

Teacher i
Teacher Wow, it's flexible
Bugscope Team probably puffs up with hemolymph
6:25pm
Teacher Yes, hemolymph. Cool adaptation
Teacher Oops, I have a student here who wants to take control a little, David please.
Bugscope Team Got it!

Bugscope Team more spinelike setae, on the hornet leg

Bugscope Team tiny crystals of some sort
Teacher The microstructure on these is intense
Bugscope Team yes it is. pretty cool

Bugscope Team good job driving

Teacher Are the grooves for increasing sensitivity?
Bugscope Team I think they make the spines much stronger, less apt to bend

Teacher Aah that makes sense

Bugscope Team Dude I am not sure what all of these bristles do, but they seem protective

6:30pm

Bugscope Team now we are at a disadvantage because the microscope is set up at a long working distance

Bugscope Team the long working distance allows us to see more at lower mag but gives us worse resolution at high mag

Bugscope Team if everything was at a short working distance we would resolve better now but we would not be able to see much of the insects when we're backed out
Student it's so Cool!

Student I learned a lot today. Thank you so much!
Bugscope Team hey good job driving, David
Teacher David has to go can you give me control one more time
Bugscope Team we are more than an inch from the pole piece
Bugscope Team hard to see here, though
Bugscope Team this is the inside of the chamber, but the camera is dying
Bugscope Team now we're using the secondary electron detector again
Student BBye!
Teacher Just wanted to see this butterfly antennae once more
Bugscope Team okay we can go to that
Student :D
Student Thank you everyone~~
Bugscope Team Thank You!
Teacher Cheers
Teacher So they really have scales on their antennae?\
Bugscope Team butterflies, moths, skippers, mosquitoes
Bugscope Team and silverfish
6:37pm
Teacher cool. No worries about the magnification. The kids lose perspective when we are in too close.
Teacher Thanks for staying late guys. I know the time difference is tough. I really appreciate it
Teacher Gotta go get ready for my other lessons today. I'll ssee you all tomorrow. Now room is ready and I won't have a cross pacific meeting to go to in the morning
Teacher Take care and have a good night
6:43pm
Bugscope Team Thank you -- sorry I got caught in a conversation with a lab denizen.
Bugscope Team see you tomorrow

Project Title	Compare and Contrast Insect and Arachnid Adaptations and Niches from Different Ecosystems
Insects To Study	Spider, mite, moth, butterfly, weevil, robber fly
Project Description	Students will collect and classify insects and arachnids from different ecosystems and compare their adaptations, habitats and niches. We will preserved specimens and send to Bugscope for further analysis. Bugscope will be integrated into my Ecology and Adaptation unit as well as connect to my Animal Phylum unit later in the year. Last year you allowed me to do two sessions over two days to accomodate all of my students. I'm hoping you will be able to do that again this year.
