• 8:39 am
• Bugscope Teamhello mr. mcgeehan!

• TeacherGood morning...just checking in. Our kids start at 8:20.
• Bugscope TeamCool. We are setting up presets.

• TeacherFYI...our pretests showed that we failed internet connectivity...but we'll give it a try. Things on my screen look fine now!

• Bugscope Teamthat should be fine. if you have lag issues with driving we can help out as well
• 8:44 am

• Bugscope TeamAlex!
• Bugscope Teammr. mcgeehan, if you notice any lag, just try staying away from "click to drive" and "focus", everything else should be just fine.
• 8:51 am

• 8:59 am
• TeacherOK...I'm back...I was just getting the laptops for the kids ready. I'm going to test the navigation now.

• Bugscope TeamDude we are still setting up and have it locked. Can you give us a little more time?
• Bugscope TeamI think 5 minutes is good.
• TeacherYep...let me know when it is ready to try...thanks

• 9:04 am

• Bugscope TeamYou are good to go, Mr McG.
• TeacherHow do I find the different presets of other specimans?
• Bugscope Teamthey should be in the lower right corner, if you dont see them then try widening your browser
• Bugscope Teamthe presets should all be to the right of the chat, maybe F5?
• TeacherOK...got them

• 9:09 am
• Bugscope Teamfruit fly ommatidia

• Bugscope Teamthese have bits of silica, we think, on them from the critical point dryer

• Bugscope Teammicrosetae
• TeacherOk...I've got to go out and greet kids...back in about 9 minutes with the crew!
• Bugscope Teamhere if you use the Adjust function you can fix the contrast/brightness
• Bugscope Teamall right! see you then

• 9:26 am
• Bugscope TeamHello! Welcome to Bugscope!
• Bugscope Teamthis is a fruit fly
• Bugscope Teamyou can see the compound eyes, the antennae, the mouth
• Studentwhy does it have 4 eyes
• Bugscope Teamit has five eyes, really
• Bugscope Teamit has two compound eyes and three ocelli
• Bugscope Teamocelli are 'simple' eyes
• Bugscope Teamon top of the head
• Bugscope Teamthe things that look like eyes in the center of the head are the antennae, which have two parts

• Studentwhat are the hairs on its eyeball?
  Bugscope Teamthey are just that hairs! but on insects we are supposed to call them setae, or seta for singular

• Bugscope Teamthere is a sort of pad portion and a branched portion

• Bugscope Teamthe hairs are there to help tell the insect the direction of wind movement

• Bugscope Teamsilver paint

• Bugscope Teamthere are setae all over bugs usually. Setae all have their job, some are for tasting or smelling and some are for feeling

• Bugscope Teamnow the edge of the stub

• 9:31 am

• Bugscope Teamthis is the doublestick carbon tape at the edge of the aluminum stub the samples are mounted on

• Bugscope Teamthis is an owlfly larva
• Bugscope Teamthis is an owl fly larva

• Bugscope Teamthey are predators as kids and as adults
• Studentwhat is an owl fly
• Studentwhy does it have feathers
  Bugscope Teamthose are sensory setae (remember setae are hairs)
• Bugscope Teamthey are not really flies -- they are more closely related to antlions
• Studentwhat are all of the feathery thingys?
• Bugscope Teamlooks like feathers doesn't it?
• Studentwhat are the horns coming out of its head

• Bugscope Teamthey are the setae covering its dorsal side
• Bugscope Teamowlflies resemble dragonflies when they are adults
• Studentwhat are the bumps on the head
  Bugscope Teamif you took the mag up on those, they look like cacti
• Bugscope Teamand as Cate says they are likely sensory

• Bugscope Teamthose are tiny setae as well
• Bugscope Teamsome of those setae are probably triggers that cause the jaws to snap shut on prey

• Bugscope Teamyou could barely see the eyes, which are on stalks
• 9:37 am

• Bugscope Teamthe eyes could be seen better from a dorsal view
• Bugscope Teamthis is a few sections of a huge millipede, or was...

• Bugscope Teamnow the ant...
• Bugscope Teamnow the millipede
• Teachertrying to get the ant head up...doesn't seem to be working

• Bugscope Teamlooks like it is getting so many commands it doesn't know what to do

• Bugscope TeamI just clicked on the ant head as well...

• Bugscope Teamthere we go
• Bugscope Teamok it should be fine now
• TeacherOk...we'll just hang out for a bit...the kids say they've got the ant head but it doesn't show up on mine
• Bugscope TeamCate had to go in a move the 'scope
• Bugscope Teamrefresh
• Bugscope Teamif you have a blank screen at all try refreshing your browser
• Studentwhat are the lines on it
  Bugscope Teamthat is some sort of texture on it that we think makes them look shiny
• Bugscope TeamMr McG do you have an image now?
• Studentwhat are those things on his head
• 9:42 am
• Teacheryep...just came up
• Bugscope Teamantennae
• Bugscope Teamand you can see one compound eye
• Bugscope Teamthe mouth is to the south, to the bottom of the screen
• StudentWhat are the holes under the antennae
• Studentno the small hair things

• Studentno the holes
• Bugscope Teamthose are the ball and socket joints at the base of the antenna
• Bugscope Teamthe small hairs are sensory

• Bugscope Teamnow you are zooming in on the eye
• Bugscope Teamants use their antennae much more than their eyes for information
• Studentwhat are the things on the antennae

• Bugscope Teamrecently there was an article about a 'living fossil' ant that has no eyes and a lot of 'primitive' features
• Studentdoes it has feathers?
• Bugscope Teamthe antennae have chemoreceptors on them that allow them to process scent information
• Studentwhy does it have feathers?
• Bugscope Teamthis is the moth, and the things that resemble feathers are scales
• Bugscope Teamthe scales are what make the moth or butterfly feel slick when you touch it
• Studentwhy are they fluffy
  Bugscope Teamthose are the feathers. it is the same as the powder that comes off them if you rubbed their wings

• 9:47 am
• Studenthow many facets make up the eye
  Bugscope Teamit could be hundreds
• Bugscope Teamone advantage of having scales is that you can slip out of a spider web -- the scales are very loose
• Studentwhy are the anttenaes cut
• Bugscope Teamthe more an insect depends on its eyes (mostly flying insects) the more facets there are typically
• Bugscope Teamhere we can see the proboscis, in the middle of the head

• Bugscope Teamso an ant that lives underground may only have 30 or so or sometimes you will find ants that have no eyes at all
• Bugscope Teamthis is just plain salt from wendys
• Bugscope Teamthe fast food place
• Bugscope Teamthe antennae are very fragile, and we do not always have pristine specimens
• Bugscope Teamit is something fun and different to look at.
• StudentWhy does it have squares on it?
• Studentthanx
• Bugscope Teamthis is pretty cool -- we think that the salt has smaller cubic crystals in it because sodium and chloride form cubes (squares) but there is also an anticlumping agent that causes the formation of tinier cubes.
• TeacherThanks guys...this class is rolling out...Another group will start up in about 10 minutes
• Studentthanks see ya later SHRED THE GNAR!
• Bugscope Teamok thanks for letting us know. and thank you all for your questions guys
• Bugscope TeamShred the Gnar
• Bugscope Teambrb to much tea
• Bugscope Teamtoo
• 9:54 am

• Bugscope Teamthis is an alien lookin' creature

• Bugscope Teamscary

• Bugscope Teamlandscape
• 10:03 am
• Student.
• TeacherWhat are we looking at?
  Bugscope Teamthese are the little setae on an owlfly larva
• Bugscope TeamHello!
• Bugscope Teamthis is the surface of the inner jaw of the owlfly larva
• Bugscope Teamowlfly larvae are similar to snapjaw ants in that they use their powerful jaws to quickly catch insects
• Bugscope Teamlittle setae, as Cate says, that look like cacti
• Bugscope Teamthe adults are also predatory and look like dragonflies
• Studentoh wow thats amazing!! how far is this magnefied
  Bugscope Teamyou should be able to see the magnification at all times in the upper right corner if you want
• Bugscope Teamfierce predators
• Bugscope TeamOwlflies are attracted to porchlights at night
• Bugscope Team1670x
• Bugscope Teamthe adults that is, that is where I usually see the
• Bugscope Teamthem
• Bugscope Teamyou can see the micron bar on the lower left
• Bugscope Team34 microns is 0.034 mm
• Studentin real life how big is the owlfly larva
• Bugscope Teamit is about the size of a capital letter in this text
• Bugscope Teammaybe a little bigger
• Bugscope Teamthe microscope can magnify over 200,000x

• Bugscope Teambut that is about the limit of a publishable image
• 10:08 am
• Bugscope Teamthis is a scanning electron microscope with a field-emission electron gun. that gun gives us very good imaging capability and lets us go much higher in mag than a normal SEM
• Studentwhat are those string like things
• Studentwhat does it look like when u are zoomed in that close? (200,000x0)
  Bugscope Teamnot much for insects unless there are some cool little things to look at like brochosomes. But even then at the distance the sample is at, it won't look very good
• Student`

• Bugscope Teamthe strings may be fungi that got onto the sample when it was in liquid
• Bugscope Teamat that mag, Van and Rory, there is not much to see

• Bugscope Teamthis is the flat surface of the front of the jaw

• Bugscope TeamOwlfly adults have huge eyes that help them see at night--that is where they get the name "owl" fly
• Bugscope Teamthis is another owlfly larva
• Bugscope Teamthis time it is on its back
• Bugscope Teamwe are looking at the ventral side, which is often more interesting
• Bugscope Teamyou can see now that it is a few mm long
• Studentoh ok wow how big is the microscope
• Bugscope Teamthe microscope is big enough to have its own room
• Studenthow much does it cost
• Bugscope Teamsort of the size of a large desk
• Bugscope Teamyou can see the huge jaws--the owlfly larva sits and waits with its jaws open until some unsuspecting prey insect gets too close, then WAP, the jaws snap shut and the owlfly gets a yummy meal
• Bugscope Teamaround $600,000
• Bugscope Teamseveral years ago; now they are a little more
• 10:13 am
• Bugscope Teamthey are related to antlions, which do the same sort of thing

• Bugscope Teamowlyfly larvae hide themselves and sometimes decorate their bodies with grains of sand to camouflage themselves
• Bugscope Teamscarab beetle!
• Bugscope Team'cause of the lamellated antennae, Annie?
• Bugscope Teamyup
• Studentwhat are the 2 banana shaped tings at bottom
  Bugscope Teamthose are antennae
• Bugscope Teamyou can see chemosensory pits in the slits that are exposed in those antennae
• Bugscope Teambut they charge up with electrons when we get too close
• Bugscope Teamthey do look like bananas or combined with the branches golf clubs
• Bugscope Teamthe samples we are looking at are coated with a very thin layer of gold-palladium
• Studentwhat are those hair things and what are they used for?
  Bugscope Teamthe hairs are really hairs, but with insects we are supposed to call them setae, or seta singular. They are used to help insects feel the environment around them. They have that tough exoskeleton, and without the setae, which are connected to nerved under the exoskeleton, they wouldnt be able to feel anything
• StudentI have cuaght a grass hoper with a stinger is that normal?
  Bugscope TeamI suspect that the "stinger" is actually a long ovipositor which the grasshopper uses to bury her eggs deep in the soil. The only insects with actual stingers are wasps, bees, and ants.
• Bugscope Teamand the gold-palladium does not always blanket the sample uniformly
• Bugscope Teamthe stinger is an ovipositor
• Bugscope Teamfor laying eggs
• Studenthow does the bug digest and eat food
  Bugscope TeamInsects eat just like you and me, by biting off a piece of food and chewing it, or by sucking liquid up through their modified mouthparts. An insect's digestive system is much like ours, only much smaller. They have an esophagus, a foregut, a midgut, and a hindgut that digest food in different ways just like our stomach and intestines. They have things called Malpighian tubules that work sort of like our kidneys do.
• 10:19 am
• Studentwhy are the insects covered in gold-paladium

• Studentwhy are they coverd in gold palladium
• Bugscope Teamthey are covered in gold-palladium to make them conductive, so that when the electron beam hits them it does not cause the images we get to flare up
• Studentkkk
• Studentwhat r those pointy things comin out of there eyes
• Bugscope Teamthe gold-palladium allows the electrons that the scanning electron microscope hits the sample with to go to ground rather than remaining in the specimen
• Bugscope Teamthose are also setae
• Student?
• Bugscope Teamthe pointy things are used to detect windspeed
• Bugscope Teamit also helps tell it if there is a flyswatter or a hand coming at it, so it can move away
• Bugscope Teamor better, as Cate, says, the direction of the wind
• Studentlalalal
• Bugscope Teamcompound eyes also have an advantage over our kind of eyes in that they are better equipped to detect movement
• StudentHow many facets make up this eye?
• Bugscope Teamchanges in what the fly sees are more readily detectable using compound eyes

• Bugscope Teamthere are hundreds to thousands of individual ommatidia -- the eye facets
• 10:24 am
• Bugscope Teamthis is the tip of the proboscis of the fruit fly -- this is where it drools on its food and then sucks it up
• Bugscope Teamit acts like a sponge
• Bugscope Teamin some insects/arthropods their food is taken in as a liquid
• Studentwhat are the little holes in the sponge

• Studentmy milkshake brings all the boys 2 the yard and there like
• Bugscope Teamthe little holes are where the digestive fluids are released and where, also, the digested fungi this fly eats is sucked up
• Bugscope TeamButterflies and moths feed on nectar from flowers and on sap and juice from rotting fruit
• Bugscope Teamanother case of liquid food

• Bugscope Teamthis is the ant
• 10:29 am
• Studenth
• Bugscope Teamyou can see that the ant has really small eyes
• Bugscope Teamand it has larger antennae
• Bugscope Teamball and socket antennae
• Studentfkkdj
• Bugscope Teamits exoskeleton is sort of fluted, which probably makes it have a nice sheen in the light, and also makes it stronger
• Studentwhat is the largest arthropod on the earth
  Bugscope TeamThe largest insect is the titan beetle, a longhorned beetle that lives in the Amazon rainforest. It can be up to 6 inches long and about 3 inches across
• Bugscope Teamblue whale?
• Bugscope TeamThis is for a couple of reasons: first it doesn't fly so it doesn't really need to process information very quickly. Second, ants live underground most of the time and they don't need big eyes. Third, and maybe this is because of 1 and 2, ants communicate almost entirely by taste and smell, so they don't need to see to know what is going on in their colony.
  Bugscope TeamThis is the reason that ants have small eyes.
• Bugscope Teamsea scorpion is the largest arthropod
• Bugscope Teamsome ants do not bother to have eyes at all
• Studentwhat do they use those hairs for on there body
• Bugscope Teamthat ever lived
• Bugscope Teamthe hairs help it to sense its environment]
• Studenthow much does the microscope weigh
• TeacherHow big was the sea scorpion and when did it go extinct?
  Bugscope Teamthey lived from 510 to 248 myo and were on average 8 inches long, but there were some that were 6ft big
• Studentwhy do
• Student0.
• Bugscope Teamthe microscope weighs a little more than 2000 pounds, I think, altogether
• Student=)
• Student88
• Studenthow much does micro
• 10:35 am
• Studentwhat is the smallest arthopod on earth
  Bugscope TeamI am not sure about the smallest arthropod, but I know the smallest insect is called a fairyfly. It is a tiny wasp and it is smaller than a dot on an i
• Bugscope Teamif you go to preset 3 you can see one tiny arthropod
• Studenthow much does an ant eat per day
• StudentHow many times its body weight can an ant carry
  Bugscope Team10-20 times its weight

• Bugscope TeamApparently the smallest arthropod is a mite--a mite with no common name
• Studenthow many mites do you think live in my bed
• Bugscope Teamthis is a mite on the body of a millipede
• Studenthow long do mites live
• Bugscope Teamcould be thousands in your sheets -- that is what they say
• Bugscope Teamwe don't know too much about mites
• Studentwhat do they eat
  Bugscope TeamThey eat bacteria and fungi and other organic matter that accumulates on the outside of the host
• Bugscope Teamthey seem to 'go down with the ship' when their host dies
• Studentjh
• Bugscope Teamno one knows too much about mites actually...because they are so small and because there are so many of them, there are not very many scientists that study mites.
• Bugscope Teamthere are supposed to be mites that live on our eyelash hairs
  Bugscope Teamthey are more at the base of the hair in the pores. I looked it up once
• 10:40 am
• Bugscope Teamwe have found a lot of mites on insects, recently even one with eyes
• Bugscope Teamand we are not sure sometimes whether anyone else knows about them
• Studentcan you get an infection from mites
  Bugscope TeamYes, chiggers are mites, and they can cause a very itchy bite. The bite can get infected. Mites related to the chiggers that we have here can vector typhus....but not in this county.
• Studenthow much of those live on our bodys
• Studentdo mites die when you put mascara on
• Studentbye
• Studenthow long do a cenipede live
• Bugscope Teamgenerally I think they are benign that way but can give you allergies from breathing them in
• Studentthank you
• Studentthanks your awsome!!!
• Studentthanku much g2g
• Studentpce brothers pce
• Studentu rock
• Studentthank u so so so much shred the gnar and i hope i will be able to see this again have a good day and again SHRED THE GNAR
• StudentPEA
• Studentthank u sooooooooo much 4 this great time but we have class so ta ta
• Bugscope Teamshred the gnar
• Bugscope TeamThank You!
• StudentTYPO
• TeacherGreat job guys...the kids loved it!!! We have a 48 minute break and will be back with the next class at 10:35 so take a break and enjoy a cup of joe.

• 11:05 am
• Bugscope Teamhi Shaun!
• 11:12 am

• 11:39 am
• TeacherOK...back with the next class, it will take them a few minutes to type in the address and get on line.
• Bugscope TeamGreat!
• TeacherBy the way...what are we looking at currently?
• Bugscope Teamthis is another mite
• Bugscope Teamon the millipede body
• Bugscope Teamit was a huge industrial-sized millipede
• Bugscope Teamand we have been cutting a few segments off at a time

• 11:44 am
• StudentWhat is that
• Bugscope Teamthat is a mite
• Bugscope Teamon the body of a millipede
• Bugscope Teamthe millipede was so big we just cut segments from its body
• Bugscope Teamif you take the mag down you can get an idea of the relative size
• Studenthow big is the microscope
• StudentIs that the real color?
• Bugscope Teamthe microscope is like a large desk, sort of
• Bugscope Teamthe real color now is silver, since we coated the whole sample with gold-palladium]
• Studentis it complicated to work?
  Bugscope TeamIt is kind of like a video game, I think
• Bugscope Teamgold-palladium takes its color from palladium, which is silver'
• Bugscope Teamno you would be good at it
• Studentwhat are the tentacle thingys on the mite?
• Bugscope Teamit takes a little while to refine your ability to control it but it is pretty straightforward
• Bugscope Teamwell tentacle is a good word
• Bugscope Teamthey are the limbs
• StudentWhat size can you compare the might to?
• Bugscope Teamamong them is the head, which is super tiny
• Bugscope Teamyou can see from the scalebar on the lower left that it is maybe 200 microns long, which is a fifth of a millimeter
• Studentdo mites live on us? if so how many?
• Studentwhat kind of bug is it?
  Bugscope Teamthey are in the same group as ticks- arachnids
• 11:49 am
• Studenthow big can they get?
  Bugscope TeamThe biggest mites are probably about 5 mm....the velvet mites that you often see in the woods.
• Bugscope Teamit is blind, and we see them frequently on insects/arthropods, apparently the same kind
• Bugscope Teamthey don't seem to get bigger than this
• Bugscope Teamyes mites live on us
• Bugscope Teamsometimes on eyelashes, and usually inside the pore the eyelash comes out of
• Bugscope Teamand dustmites are said to make up a large proportion of the weight of an old pillow

• Bugscope Teamhard to believe
• Bugscope Teamdustmites are different
• Bugscope Teamfrom these
• Bugscope Teamthis is the compound eye of a fruit fly
• Studentis there anything that you can do to get mites off of your body, like a shower?
• Bugscope Teamthe spikes are setae (or seta for just one) which are like hairs
• Bugscope Teamkeeping yourself clean and healthy keeps you from having too many
• Bugscope TeamI think you cannot really rid yourself of them
• Bugscope Team(for the mites question)
• Bugscope Teambetter than having lice
• Bugscope Teamthe facets of the fruit fly eye are called ommatidia
• 11:55 am
• Studentwhat is the dust-like stuff on the facets?
  Bugscope Teamthat is just dust or dirt or some stuff that got on it from when we dried it
• Bugscope Teamand the setae between them are said to be useful in assessing the direction of the wind
• Studentwhat are the setas for
• Studenthow many eyes do u think they have?
• Bugscope Teamthey give the fly an idea of the direction of the wind
• Bugscope Teamsomeone has counted the ommatidia on fruit flies....

• Studentis there a reason for the hexagon-shaped facets?
  Bugscope Teamthey allow the eyes to have curvature by being that shape
• Bugscope TeamI imagine there are close to 2000

• Studentwhat got u interested in this kind of job?????
• Bugscope TeamI wanted to be able to do something concrete in science
• Bugscope TeamI just like science in general. By working with microscopes, I get to see a whole lot of sciences like engineering and biology
• Bugscope Teamsomething that would not require too much interpretation, such as producing images of real things, real phenomena
• 12:00 pm
• Bugscope Teamwe do get exposed to all kinds of cool edge research
• Studenthow much does the microscope cost?
• Bugscope Teamand that is sort of addictive, in a good way
• Bugscope Teamthe 'scope cost about $600,000 in 1998
• Studentwhy is it important for the facet to have curvature?
  Bugscope TeamWell, they have to curve because the eyes are rounded. And the eyes are rounded because they help the insect to see in all directions around its body
  Bugscope Teamfor instance, with this fruit fly the eyes take up most of the head. Because of the curvature, they can see almst 360 degrees around them
• Bugscope Teamwe work in a suite full of about 20 microscopes
• Studenthey! how much does the microscope weigh??
• Studentwhat are the thorn things next to the eye on the top right?
  Bugscope TeamThose are setae, which are kind of like hairs. They help the insect to sense its environment
  Bugscope Teamthose are some kinds different setae
• Bugscope Teamwe have a transmission electron microscope as well, plus lots of light microscopes and atomic force microscopes
• Bugscope Teamsetae can help the insect sense chemicals (smells) as well as things that might be touching them
• Bugscope Teaminsects have an exoskeleton, and the setae stick through and are connected to nerves on the inside of the body

• Bugscope Teamit's like if you were wearing armor, you would not be able to sense things touching it very easily
• Bugscope Teamthe setae we see here on the tarsus are what help this insect climb walls
• Bugscope Teamthey are called tenent setae
• 12:05 pm
• StudentHow many colors does a fly see?
• Bugscope Teamsometimes when we see them on flies, among other insects, they resemble little suction cups
• Bugscope Teamit probably depends on the fly, but generally I think they see all the colors we see and sometimes more
• Studentwhat perpose do bugs have?
  Bugscope Teamvery important purposed- like decomposing dead matter or pollinating plants to name a couple
• Studentwhy do you have to cover the insects with gold palladium
• Studentdoes the microscope ever break
• Bugscope Teamsome insects can see ultraviolet light, which we do not
• Studentwhat r the little bristles for??
• Bugscope Teamgold-palladium makes the electrons that hit the insect while we are imaging it run off to ground rather than building up in one place
• Bugscope Teamit's like attaching wires to it so the electrical energy can be shed instead of causing the area we are viewing to charge up with electrons
• Bugscope Teambasically it helps us get better images
• Studenthow much does the microscope weigh??
  Bugscope Teampretty heavy. we wouldnt be able to lift it
• StudentHow long do flies live?
  Bugscope TeamThere are a lot of flies and they have a lot of variation in life spans. A housefly probably lives about a month from the time it is an egg to the time it dies as an adult. Of course, their life could be longer or shorter depending on the weather, the time of year, and the availability of food.
• Bugscope Teamthe images that we see from the 'scope now come from the gold-palladium releasing what are called secondary electrons from the surface of the bug

• Bugscope TeamI think it weighs a little more than a ton altogether
• 12:10 pm
• Bugscope Teamwe brought the microscope in using a pallet jack and assembled all of the pieces
• Bugscope Teamit has its own air, water, nitrogen, and electricity
• Bugscope Teamif you see a small fly it will not grow up to be a big fly
• Studentdo all ants have the same partern of lines on its body or are they all difforent like ower finger print
  Bugscope TeamEach species is a little different for sure. I am not sure if each individual ant is different...that is a good question though.
• Studentdo the ants have compound eyes
  Bugscope TeamYes, most of them so. But the eyes of ants are generally much smaller than the eyes of many other insects.
• Bugscope Teamwe think the lines make the ant look shiny
• Studentare the eyes as big as the flys
  Bugscope Teamno, much much smaller
• Bugscope Teamno the ant has very small eyes
• Bugscope Teamyou can see the little eye, right under the bend in the antenna
• Bugscope Teamants use their antennae for communication/sensing what is around them much more than they use their eyes
• Bugscope Teamsome ants doon't bother to have eyes
• Bugscope Teamand recently someone discovered a 'living fossil' ant that has no eyes and has other features like soft mandibles that are considered primitive
• Studenthow powerful are an ants mandibles?
• Bugscope Teamthe idea is that ants might have started off underground, without eyes, millions of years ago
• 12:16 pm
• Studenty would th ants NEED ball&socket joints on their antenae?????
• Bugscope Teamants can cut leaves with their mandibles, and they can disassemble small animals/insects
• Bugscope Teamthe ball and socket joint allows great mobility
• Bugscope Teamso the antennae can be moved where they are needed
• Studentdo ants have other joints like we have other than their antennae?
  Bugscope TeamThey have many joints, there are joints between all the moving parts of an ants body. Kind of like a knight's suit

• Studentwere ants bigger millions of years ago??????
  Bugscope TeamAnts were probably never much bigger than they are now. Ants have an extraordinary range of sizes, from almost microscopic to almost 2 inches long.
• Bugscope Teamthe spikey things are bristles/setae that probably function much the same as cat whiskers
• Bugscope Teamants could have been bigger millions of years ago in general because there was more oxygen in the air
• Bugscope Teambut not much bigger
• Studenthow fast could a swarm of army ant eat all the food in a 10 by 10 meter area?
• Studenthow much weight can a single ant carry
  Bugscope Teamthey can carry 10-20 times their own weight

• Bugscope TeamThomas Eric I am not sure how long it would take but it would seem to be very quick
• 12:21 pm
• Studentbye scot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Studentthnk u so much^^ bye!!!!
• Studentthanks
• Bugscope TeamHey Thank You!
• Studentthanx scot!!!!! peace out annie!!! GTG
• TeacherThanks Annie and Scot...kids are heading out and that is all for us. You guys rock!!! The kids love it.
• Bugscope TeamAnd Cate!
• Bugscope TeamThank you!
• Bugscope Teamsee you next time...
• Bugscope Teamthank you for all your questions
• Bugscope Teamhey can you log me off as ScotJ? please?
• Bugscope Teamand as always you can access your images and transcript from your member page
