Connected on 2007-10-26 11:00:00 from Ho-Ho-Kus, NJ, US
- 10:44am
- Bugscope Team I am going to run up for food in a minute
- Bugscope Team ok
- Bugscope Team presets are done. we are ready for the session.
- 10:52am
- Teacher hi there, just checking in
- Bugscope Team welcome to bugscope!
- Bugscope Team i've just unlocked the session, you can start practicing if you want.
- Teacher I still have to get set up with my students---we'd be ready to start at about 11:10 your time...
- Bugscope Team sounds good.
- Bugscope Team if you have any questions or problems just let us know if we can help.
- Teacher I'm just going to cruise around a bit..
- Bugscope Team Ms J is this the first time you have worked with this interface?
- Bugscope Team coolness, the scope is all yours ms. j
- Teacher No, I think I used it during our session this past June
- Bugscope Team It should be a little better, more responsive
- Teacher yeah, I had some trouble the last time with it now that I recall
- Teacher wow this is so much better!
- Bugscope Team :)
- Bugscope Team you have seen us through bad and good
- Teacher I've been doing bugscope with the 5th grade for many years now--I think this is year 5?
- Bugscope Team Chas put this together, and he started working for us when he was a sophomore in high school
- Bugscope Team now he is a grad student
- Teacher I feel really old.
- Bugscope Team that wasn't intended to make you feel old
- Bugscope Team well, i have lots of grey hair...
- 10:57am
- Bugscope Team and i'm only 36.
- Teacher :-)
- Bugscope Team so i LOOK old
- Bugscope Team I feel older. We've got markings on the ESEM room doorway documenting my height changing about 2 feet
- Teacher OK, I'm going to get set up in my classroom. I'll see you all in about 12 minutes or so...
- Bugscope Team really chas? that's cool. where?
- Bugscope Team yeah that's true I was a lot taller than Chas when he started
- Bugscope Team cool
- Bugscope Team oh yeah, i seem the markings now
- Teacher BTW, I think my password was margaret?
- Bugscope Team yes
- Bugscope Team Yes, but the students shouldn't need it to login
- Teacher OK, thanks.
- Teacher see you in a bit
- Bugscope Team When they visit the login page it should identify them as from the same school and only ask for a chat nickname
- 11:13am
- Teacher Hi, we have one of our 3 5th grade homerooms ready to view some bugs
- Bugscope Team Great!
- Bugscope Team sounds good!
- Bugscope Team here we are looking at butterfly scales, very close up
- Bugscope Team they are sort of like shingles on a house
- Bugscope Team but really they function like feathers do on a bird wing
- Teacher what type of butterfly was this?
- Bugscope Team the one you sent us, a monarch
- Bugscope Team if you look at the micron bar, to the left, 2 microns is the length of a bacterium
- Bugscope Team this is just a piece of the wing
- Bugscope Team i painted the edges with silver paint to help with the charging
- Bugscope Team butterfly wings LOVE to charge up
- Bugscope Team which is what that weird contrast is
- Bugscope Team the whole Monarch would cover the aluminum stub that all of the sample are mounted on
- Bugscope Team if we want to get good images of the scales close up, we go to an edge where there is silver paint, and we look right adjacent to that
- Bugscope Team here is part of an ant
- Bugscope Team the left part is a compound eye
- Bugscope Team the right is part of the head
- 11:18am
- Bugscope Team It looks like an ant
- Teacher This is so cool!
- Bugscope Team Ants usually have very small eyes. They uses smell and "taste" to navigate in their environmnst
- Bugscope Team environment
- Bugscope Team with some ants the compound eye is very very simple, like it has only a few ommatidia
- Bugscope Team this one has a relatively complex compound eye
- Bugscope Team and some ants are blind -- they depend only on their antennae
- Bugscope Team you can see in the background that Cate put silver paint down to get the ant to stick better and to make a better conductive pathway for the electrons
- Teacher why do you have to have a pathway for electrons?
- Bugscope Team if the elecrtrons that impinge on the sample do not have anywhere to go, the sample will charge up and give us a poor image
- Bugscope Team [electrons] that is what we saw with the Monarch wing, where we had poor conductivity
- 11:23am
- Bugscope Team scales are notoriously difficult to make conductive
- Teacher does this ant have hairs?
- Bugscope Team most insects have lots of 'hairs', or setae. ah there are some!
- Bugscope Team now you can see a few setae, as Alex said
- Bugscope Team now we can see why roly polies are Isopoda
- Teacher why are they isopods?
- Bugscope Team iso means the same, like in an isosceles triangle
- Teacher or not bugs?
- Bugscope Team the setae serve a variety of purposes, they help the insect to feel, taste and smell
- Bugscope Team and pod means foot
- Bugscope Team all of the feet are the same
- Bugscope Team they are not insects
- Bugscope Team they are arthropods, though
Bugscope Team They're arthropods, but their subphylum is Crustacea meaning they're more closely related to shrimp, lobsters, etc
- Teacher we just got a huge response from everyone here1
- Bugscope Team me too, i almost screamed!
- Bugscope Team you mean because the pillbug is so lovely?
- Teacher everyone here thinks he looked pretty sad. Probably becuase he's dead.
- Bugscope Team a face only a mother pillbug could love
- 11:28am
- Bugscope Team awww
- Bugscope Team he does look like hes sad
- Bugscope Team we should be able to see his eyes
- Bugscope Team tasty big insects
- Teacher where are the eyes? are they near the antennae
- Bugscope Team they should be under the curve of the antenna there
- Bugscope Team wow you can barely see the eye
- Bugscope Team this is the base of the antenna
- Bugscope Team good job driving!
- Bugscope Team ok now a tiny bit to the left I think
- Bugscope Team ok
- Bugscope Team now you can see those little round beads
- Bugscope Team oops not now
- Bugscope Team the eyes are nothing to write home about
- Teacher yeah, I think I clicked by mistake
- Bugscope Team You can probably tell based on the small size of the eye that they do not rely heavily on sight
- Bugscope Team I had expected they would show up better
- Bugscope Team they live in dark places...no need to see things if it is always dark!
- Teacher what's a haltere?
Bugscope Team haltere's, also known as balancers or poisers, are small knobbed structures found as a pair in some two-winged insects; they are flapped rapidly to maintain stability when flying.
- 11:33am
- Bugscope Team dipterans have two wings, and two halteres to balance the movement of the wings
- Bugscope Team it is a modified wing
- Teacher someone asked if it is like a rudder
- Bugscope Team it has those hypertrophied mechanosensors on it, and it beats opposite the way the wings beat
- Bugscope Team @copyright, wikipedia. :)
- Bugscope Team when the fly is alive, the end of the haltere is swollen like a boxer's punching bag -- like a speedbag
- Bugscope Team No entomologists refer to them as balancers or poisers...
- Bugscope Team they are like gyroscopic stabilizers
- Teacher is this the mouth?
Bugscope Team yes, you could try to lower the contrast
- Bugscope Team Ms J this is the mouth and you can see the antennae above
- Bugscope Team sort of mouth
- Bugscope Team this looks like it is charging up with electrons
- Teacher what are those two ovals at the top?
- Bugscope Team deus ex machina
- Bugscope Team those are the antennae
- 11:39am
- Bugscope Team the antennae have an oval component and a branched component
- Bugscope Team Flies have what we call "sponging" mouthparts, kind of like a sponger on the end of a straw connected to their heads...not the most technical of descriptions
- Teacher ewwww.
- Bugscope Team yeah this is gross
- Teacher what are all those pointy parts?
- Bugscope Team those are tiny setae that probably have to do with tasting the food
- Teacher are the long white ones setae too
- Bugscope Team like little taste buds on your tongue
- Bugscope Team small setae and big setae
- Bugscope Team they are also called setae, but we call lots of things setae
- Bugscope Team spme of the longer ones may be mechanosensory like a cat or rat's whiskers
- Bugscope Team eeeuw
- Teacher is that long ribbon the tongue?
- Bugscope Team the spongy tongue would be more gross if it was not dried out a bit
- Bugscope Team yes right in the middle, the curved part
- Teacher did it die with its tongue hanging out?
- 11:44am
- Bugscope Team it pretty much always has its tongue hanging out
- Bugscope Team so yes
- Bugscope Team they spit up on their food to solubilize it so they can suck it up
Bugscope Team but they dont 'spit up' everytime they land
- Bugscope Team mmmm
- Bugscope Team I think I am right -- that flies do not chew their food but eat it as a liquid
Bugscope Team In some flies...house flies do that
- Bugscope Team uhoh
- Teacher did the millipede break? There is a big hole in it.
Bugscope Team i squished it picking it up on accident
- Bugscope Team horse flies slash their food so they can suck it up
- Bugscope Team yeah sorry we broke it
- Teacher ouch
- Bugscope Team Mosquitoes, horse flies, fruit flies---I think most flies do consume liquid food
- Bugscope Team I can say anything as long as Annie is here to correct me.
- Bugscope Team it's empty!
- Bugscope Team looks like there is a scale on the edge there
- Bugscope Team then I will have to be more careful
- Bugscope Team you can kind of see the dried up muscles
- Teacher eww
- Bugscope Team the stuff that looks like little pieces of beef jerky
- 11:49am
- Teacher yum.
- Bugscope Team we have looked at mealworms before and seen the muscle attachments on the inside of the cuticle
- Teacher is this millipede decapitated?
- Bugscope Team yes Cate was so very careless : )
- Bugscope Team this is where the head should have been
- Bugscope Team i did not decapitate it
- Bugscope Team it was already in that state
- Teacher was this where the head was?
- Bugscope Team Where all of this juju is
- Bugscope Team as alex said before, something chomped on it :p
- Teacher did you have a live cricket in our "collection of bugs"?
- Bugscope Team ah ha
- Bugscope Team it was dead when it arrived; maybe that is what killed it
- Bugscope Team oh Cate said it was alive
- 11:54am
- Bugscope Team now we are looking at scales, up close
- Teacher we have another group coming in--we'll be back in a minute or two
- Bugscope Team ok!
- Bugscope Team great! we will be here
- Bugscope Team bye bye
- Bugscope Team Bye!
- Bugscope Team Ms J Annie had to leave for a meeting
- Bugscope Team she would have preferred to be with us
- Bugscope Team she is our entomologist
- Bugscope Team keeps us on the straight and narrow
- Bugscope Team so we dont call lobsters bugs :p
- Bugscope Team she did start to concede a little last time -- they do have antennae!
- Bugscope Team how many legs do they have?
- Bugscope Team it has like 10 or something
- 11:59am
- Bugscope Team if you include those claws
- Bugscope Team so it is like an isopoda
- Teacher We have a new class now so the questions might be similar
Bugscope Team thats ok we are used to it ^.&
- Bugscope Team but we might give different answers
- Bugscope Team that was super high mag
- Bugscope Team it is difficult to look at scales closely with the microscope set up this way
- Bugscope Team we are far from the sample so we can get good low mag images
- Bugscope Team but that means when we want to look close we don't have the advantage of better resolution from being physically close
- Bugscope Team now you can see charging, where the scales in the middle of this wing segment are lit up
- Teacher can we see the whole butterfly/ wing
- Bugscope Team it is not all on here Ms J, because it was so big
- 12:04pm
- Bugscope Team this is just a section of it
- Bugscope Team if we put the whole wing on we would not be able to put anything else on the sample stage
- Bugscope Team the scales are what make the wings feel so silky
- Bugscope Team they rub off easily, which is part of the reason it is hard to keep them from charging up with electrons when we image them
- Bugscope Team this is the ant eye, and the ant's head
- Bugscope Team now you can see the antennae
- Bugscope Team the jaws are to the NE
- Bugscope Team if you look towards the mouth you will see little feelers coming out
- Bugscope Team the eye is a compound eye, meaning that it has many facets, called ommatidia
- Bugscope Team each of the ommatidia gets an image
- Bugscope Team it looks like he's eating something, but it's part of his mouth
- Bugscope Team now you can see the jaw
- Bugscope Team yeah ants often look as if they have some other critter in their mouths
- Teacher why does it look like it has small dots on it
Bugscope Team i think those are pores where the setae are coming out
- Bugscope Team those dots are places where setae (tiny hairs) stick through the chitin
- 12:10pm
- Bugscope Team the setae are sensory -- they help an insect sense/feel/smell its environment
- Teacher why do the have so many scales
- Bugscope Team that is the way the cuticle is formed, and it almost certainly makes the structure of the exoskeleton stronger
- Bugscope Team instead of being smooth
- Bugscope Team ants have big muscle heads
- Teacher what is that hole for
- Bugscope Team this one has a little ridge above the ball and socket joint where the antenna is
- Teacher how is the antennea connected
- Bugscope Team it is connected at the joint there and has lots of nerves that go inside to the brain
- Teacher how big is the eye
- Bugscope Team antennae are very important to an ant
- Bugscope Team it is a little more than half a mm
- Bugscope Team you can see the micron bar to the left
- Bugscope Team now we can see the individual facets of the eye -- the ommatidia
- 12:15pm
- Bugscope Team they are generally round, and when they are close packed like this they are often hexagonal
- Bugscope Team this is one of the limbs of the pillbug
- Bugscope Team it is dirty, and I wonder what we can see in the dirt
- Bugscope Team sometimes there are diatoms visible in dirt
- Bugscope Team these guys crawl around on the ground and pick up all kinds of things
- Bugscope Team you can see what look like plant parts
- Bugscope Team the thing on the bottom is probably plant fiber
- Bugscope Team OOF
- Bugscope Team maybe to the left?
- 12:20pm
- Bugscope Team Ms J is the driving working? It's not hung up is it?
- Teacher we are not getting an image
- Bugscope Team try using the refresh button on your browser
- Bugscope Team hit refresh
- Bugscope Team d'oh!
- Bugscope Team we lost Cate
- Bugscope Team i'm here i swear!
- Bugscope Team now we lost Ms J!
- Bugscope Team ouch
- Bugscope Team looks like they lost their internet connection... maybe?
- Bugscope Team i'll try calling.
- Bugscope Team She is resourceful she will be back
- Bugscope Team hi ms. j
- Bugscope Team i'm just trying to call you.
- Student don't know if this will work...
- Bugscope Team it should work now
- Bugscope Team i just gave you control.
- Bugscope Team Your students will maybe think it is funny that you are signed in as a student
- Student we're back...
- Bugscope Team ms. j, try, ah yes, i see you are moving the scope now. coolness!
- 12:25pm
- Bugscope Team good driving!
- Bugscope Team its like one of those curly up mustaches on his mouth
- Bugscope Team you can see the little jaws, now
- Bugscope Team sharp little jaws
- Bugscope Team see the little seta?
- Bugscope Team to the right?
- Student yes
- Bugscope Team ms j. occasionally you might see a black screen image. if that happens, and doesn't go away in 3-4 seconds, then try hitting refresh (F5). that should fix it.
- Student ok
- Bugscope Team now we are looking right into the mouth, as much as we can, and now we see the setae that probably let it taste what it will be eating
- Bugscope Team the eyes are very hard to see because they look more upward than down
- Bugscope Team now we see the haltere on the fly
- Bugscope Team there will be two of these
- Bugscope Team one on each side
- Bugscope Team they are micro-sized former wings
- Student everyone is grossed out
- Bugscope Team its kind of there, you can see the stem
- 12:30pm
- Bugscope Team I think we are used to this by now
- Bugscope Team hey you found the millipede on your own!
- Student whoops
- Bugscope Team you can see that when Cate made the sample she mounted the fly on its back
- Bugscope Team that is so we can see the legs and face
- Bugscope Team ahhh bright lol
- Bugscope Team all of those setae that stick out are almost certainly mechanosensory
- Bugscope Team cool, good control of the brightness/contrast
- Student we're assuming that's the eye on the left
- Bugscope Team often a female fly's eyes are far apart, like this, and those of a male are close together
- Bugscope Team yes that is the right eye on the elft
- Bugscope Team yes, that's a compound eye. a big one.
- Bugscope Team lefet
- Bugscope Team you can zoom in on it if you want
- Bugscope Team left
- Bugscope Team now you can bring the mag up if you want
- Bugscope Team all those individual eye facets are called ommatidia.
- Bugscope Team to see the ommatidia, as Alex says
- Bugscope Team ooh nice
- 12:35pm
- Student so these aren't hexagonal
Bugscope Team ah, good eye! i just noticed that. that is interesting isn't it. most compound eye ommatidia are hexogons i believe...
- Bugscope Team let's go up close and see
- Bugscope Team ah, wait, these are too!
- Bugscope Team they may be hexagonal but angled away from us
- Bugscope Team just harder to see
- Bugscope Team now adjust the focus a little
- Bugscope Team this is exciting
- Bugscope Team each ommatidium has it's own cornea, lens, and photoreceptor cells.
- Bugscope Team this is where we would be able to see bacteria, if there are any
- Bugscope Team Nice!
- Bugscope Team ms. j, you RULE at controlling the scope.
- Student could the eye still work if one of the "eyes" is poked out?
- Bugscope Team the microscope is parfocal, so if you were to take the mag down you would still be in focus as long as oyu did not move
- Bugscope Team yes if one eye was poked out or obscured there are a lot of other ones to take its place
- Student ewww
- Bugscope Team the brain is largely devoted to optic nerves -- to visual processing -- in a lot of flies
- Bugscope Team compound eyes have poor resolution in general, however they are GREAT for detecting fast moving, like other bugs and such. compound eyes also have a very WIDE angle of view, so they can see lots of stuff.
- Bugscope Team some insects can also see in the ultraviolet -- out of the range of visible light
- 12:40pm
- Bugscope Team we cannot see in the ultraviolet
- Bugscope Team some eyes like fly eyes have almost 360 degree view
- Bugscope Team this is the edge of the fly tongue
- Student lots of screaming
- Bugscope Team the eye to the left (the right eye) is busted
- Bugscope Team me too! ahhhh!!!!!!!
- Student yuk
- Bugscope Team Cate is such a savage she must have dropped the fly
- Bugscope Team i didnt do it before you blame me scott >.>
- Bugscope Team on the top of the head are the antennae
- Bugscope Team too late Cate
- Bugscope Team wow! the compound eye is cracked! very interesting.
- Bugscope Team Actually I don't know how you would do this on purpose
- Bugscope Team *sigh*
- Student should I use the + or - to focus?
- Bugscope Team so you know I was just teasing Cate
- Bugscope Team +
- Bugscope Team it's hard to know which one. try one, if it gets worse, then use the other.
- Bugscope Team 'cause I just tried it
- Bugscope Team cool
- Bugscope Team Nice!
- Bugscope Team wow, i've never seen a cracked compound eye before, this is sweet!
- Bugscope Team this is a good opportunity to see what is inside
- Bugscope Team wow
- 12:45pm
- Bugscope Team It looks fibrous
- Student is that muscle under the eye?
- Bugscope Team are those muscle fibers under the facets?
- Bugscope Team I imagine those are lots of nerve bundles
- Bugscope Team they have to be linked well to the brain
- Student this is really cool
- Bugscope Team yeah, that makes sense, they don't need muslces there, they just need nerves to send the signals to the brain....
- Bugscope Team i'm guessing though. i'm not a biologist.
- Bugscope Team you know the ommatidia looked more like lenses than I had thought -- like little crystals
- Bugscope Team eeeeuw
- Student what is this?
- Bugscope Team this is one of the spiracles
- Bugscope Team this is an airhole
- Bugscope Team this is what insects breathe trhough
- Bugscope Team through
- Student is this on the mouth?
Bugscope Team gopod question, but no, spiracles are usually on the body of insects.
- Bugscope Team there are usually two on each body segment, on either side
- Bugscope Team no it is just on a body segment
- Bugscope Team we have to remember that insects have an exoskeleton, which means the hard bony part of the body is on the outside
- Bugscope Team imagine if you breathed through a hole on the side of your body. cool huh?
- Bugscope Team you can see its butt
- Bugscope Team it is like if you were wearing armor all of the time
- 12:51pm
- Bugscope Team if you were wearing armor you would not be able to use the nerve endings in your skin to feel what might be touching you
- Bugscope Team oo good analogy
- Bugscope Team so you would want something to stick through the armor that would send a touch or smell message to your skin
- Bugscope Team that's why insects have the setae (hairs) that stick through the armour. those setae help the insect to sense it's environemnt. yeah, scott, good analogy, you are on fire today!
- Student good one!
- Bugscope Team and also you would want to be able to breathe through your armor
- Student ok, we have another group coming in...give us a few minutes.
- Bugscope Team which is what spiracle are for
- Bugscope Team spiracles
- Student this will be our last group, too.
- Bugscope Team ok, this is fun.
- Bugscope Team insects can close their spiracles and hold their breath, like if you put then in the microscope alive they would just hold their breath until you let them out again
- Bugscope Team though i'm sure they won't like getting hit with electrons
- 12:57pm
- Student one group is delayed. so bear with us!
- Bugscope Team we are fine -- thanks!
- Bugscope Team no problemo
- Bugscope Team If we put a live roach in the 'scope and imaged it for a few minutes it could just hold its breath until we let it out again
- Bugscope Team yep, but it would have to stay still
- Bugscope Team Man there is not much air in here so I am going to close my spiracles.
- Bugscope Team we would have to use wax tethers
- Bugscope Team maybe use some of that sticky stuff from a roach motel to keep it still
- Bugscope Team if it doesn'
- Bugscope Team t outgas
- Bugscope Team keep those spiracles closed tight!
- 1:03pm
- Bugscope Team yay!
- Student we're back with a new group
- Bugscope Team Great!
- Bugscope Team this is the millipede
- Student is there a double set of legs at the top curve?
- Bugscope Team and you can see in some places where there are scales on it from a butterfly wing
- Bugscope Team let's go look!
- Bugscope Team we can figure out how many legs it has per segment
- Bugscope Team you can try click to center if you want, sometime
- Bugscope Team when you use click to center you don't have to stop
- Bugscope Team I think there are pairs of legs that are opposed
- Bugscope Team it is hard to see where they orginate
- Bugscope Team originate
- Student Ok, it just looked a little dense there.
- Bugscope Team here is where the head was, and where we think the cricket had a little snack
- Student what is all this stuff coming out of its body
- 1:08pm
- Bugscope Team yeah lot of stuff
- Bugscope Team in insects the blood is called hemolymph
- Bugscope Team this is analogous to that I think
- Student so, maybe this is dried blood
- Bugscope Team they have an open circulatory system, and I think it is the same with millipedes and roly polies
- Bugscope Team all of the organs inside the body cavity are bathed in that fluid, which is hemolymph in insects
- Bugscope Team here is where the cuticle broke
- Student these kids are curious about the hole
- Bugscope Team ask cate about it ; )
- Bugscope Team i poked it picking it up
- Bugscope Team it crunched
- Bugscope Team you can tell that the exoskeleton is very dry now
- Bugscope Team Well...now we get a little peak inside
- Bugscope Team heh it all oozed out when its head popped off
- Bugscope Team see where things are very white? that is whre the electrons are not going to ground
- Bugscope Team we may be seeing muscle now
- 1:13pm
- Bugscope Team when we prepare samples we coat them with gold-palladium to make the surface conductive
- Bugscope Team when we use an electron microscope the sample is in a vacuum, and we beam electrons at it
- Bugscope Team the electrons pass across the sample in an orderly, repeated manner
- Bugscope Team and they knock other electrons out of the coating on the surface of the sample
- Bugscope Team the electrons that come out of the sample are called secondary electrons, to distinguish them from the beam, which is primary electrons
- Bugscope Team all this will be on tomorrows exam...
- Bugscope Team we collect the secondary electrons into the images we see
- Bugscope Team heh
- Student what are the scales made out of?
- Bugscope Team they are made out of protein, and it is still chitin I think
- Bugscope Team like what the exoskeleton is made out of
- Bugscope Team butterflies, moths, skippers, mosquitos, and silverfish have scales
- Bugscope Team if you go closer, you'll see that the scales have ribbed parts (thicker) and then thin parts inbetween that quite often have holes in them.
- 1:18pm
- Bugscope Team or, how about always have holes in them.. wow. is that normal scott?
- Student are those spaces between each?
- Bugscope Team it seems like they always have holes in them but the patterns can be very different
- Bugscope Team yes those are spaces
- Bugscope Team I am still not sure if scales have colors
- Bugscope Team I think they do
- Bugscope Team but they are small enough to refract light and give you structural colors
- Bugscope Team like if you look at the surface of a record, or if you look at the feathers on a crow's wing and they give you multiple colors
- Bugscope Team those are also called or more properly called interference colors
- Bugscope Team we lost Ms J again!
- Bugscope Team Maybe she was bored listening to me...
- Bugscope Team yay you're back
- Student We're back, again!
- Bugscope Team hi ms j 2!
- Bugscope Team no that couldn't be it
- Student No, you weren't boring us.
- Bugscope Team yay!
- Bugscope Team i just gave you control, it should be working again.
- 1:23pm
- Student I can't get to the other specimensit says valid session ID not received?
- Student oK, we're back
- Bugscope Team hmm, try hitting refresh (F5), and then try again.
- Bugscope Team yay!
- Bugscope Team this is the ant eye, and the surface of the side of the head
- Bugscope Team it haas little crenulations in it
- Bugscope Team that probably make the surface much stronger
- Student what's a crenulation?
- Bugscope Team it means having an irregular or wavy appearance
- Bugscope Team or a serrated outline
- Bugscope Team very similar to crenelations in a castle
- Bugscope Team like the top of the wall of a castle with those places to shoot bows and arrows and cannons through
- Bugscope Team this is the antenna base
- Bugscope Team its a ball and socket joint it looks like
- 1:28pm
- Bugscope Team we can see what looks like mold on the surface of the ant
- Student why does the ant have such long hair
- Bugscope Team and lots of tiny setae
- Student that's mold?
- Bugscope Team It's like what grows on your food when it rots -- those fine fibers
- Bugscope Team Really, Scott...
- Bugscope Team abdomen
- Bugscope Team sorry
- Bugscope Team I didn't read your question right, I am sorry
- Bugscope Team but now you can see that the setae are covered with mold
- Student we just were curious about the mold.
- Bugscope Team What happened was that the ants were in a container that we closed the top on, and mold that was already in the air started to grow on them
- Bugscope Team it would have been better if we had not closed the top of the container
- Bugscope Team so there were lots of setae (hairs), and there was mold attached to them
- 1:34pm
- Bugscope Team this is the mouth of the roly poly
- Student do roly polys have a tongue?
- Bugscope Team I don't know; I think we are seeing as much of the mouthparts as we usually see, and it looks like these parts cut the food
- Student looks like a crab mouth.
- Bugscope Team well it is related to crustaceans, so you are right
- Student a student is curious to know if you could tell the age of some of the bugs
- Bugscope Team and you know when you see them eat their mouths move in many directions
- Bugscope Team We know that when an insect gets wings it becomes an adult, like a fly for example, and it does not grow after that. So if you see a small fly it will not be growing up into a large fly.
- 1:39pm
- Bugscope Team the part of the face next to the eyes is called the vestiture
- Bugscope Team it's like the dressing of the head
- Bugscope Team sometimes it has patterns in it that other flies can recognize.
- Bugscope Team or other insects can recognize
- Bugscope Team now the gross part
- Bugscope Team ha!
- Bugscope Team these are mostly sensory setae, we think, but they may be shaped that way to hold the digestive jiuces against the tongue
- Bugscope Team this is the tongue, which is spongy
- Bugscope Team when the fly is alive it is not so shriveled and dried out
- Student what is the area right above the tongue?
- Bugscope Team the sort of u-shaped part is the antennae
- Bugscope Team the antennae are above the mouth which causes a lot of charging
- Bugscope Team and the tongue is in a sort of box
- Bugscope Team that as Cate says is why the sample looks so bright today
- 1:44pm
- Bugscope Team it is charging up with electrons
