- Bugscope Team we are setting up
- Bugscope Team Hello K!
- Guest thank you
- Bugscope Team K I am setting the presets up for the session that starts at 3:30 our time.
- Bugscope Team Hello!
- Bugscope Team We are done setting up for today. Let use know if you have questions or if you would like to drive.
- Bugscope Team This is a daddy longlegs.
- Bugscope Team and this is a pollen grain. to the south and west of it is a mold spore, partially deflated
- Bugscope Team guest1 things usually don't start happening until the school logs on. so please let us know if you have any questions or want to see anything in particular on today's sample stage.
- Bugscope Team MrsB!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team it works, doesn't it?
- Teacher Greeting. This is Laura from ADM. We're checking out the site before kids get in here.
- Bugscope Team totally cool
- Bugscope Team drive around and check things out, do what you would like
- Bugscope Team this is a pollen grain, like ragweed or something -- I think many of them look like this
- Bugscope Team and below it we see see a sort of deflated mold spore
- Bugscope Team you can take the mag low low low to see where you are
- Teacher What's that embedded in?
- Bugscope Team if you want
- Teacher What's that embedded in?
- Bugscope Team it's on one of the limbs of the daddy long legs, so you see lots of setae (hairs)
- Teacher We thought they looked like hairs -- we were right!
- Bugscope Team yes of course we are supposed to call them setae or microsetae or trichae, etc.
- Teacher Do daddy long legs have pinchers? or are those mouth parts?
- Bugscope Team but even entomologists will call them hairs
- Bugscope Team those are pinchers
- Teacher How do we move the image around so we can look for the mouth?
- Bugscope Team it's upside down -- this is the underside of the body
- Teacher ok - but can we move the image?
- Bugscope Team if you use click to center, that's the best way
- Teacher or just zoom?
- Bugscope Team activate click to center, and then put your mouse on the image and click to get the 'scope to move to that region
- Bugscope Team I think the deal is that we cannot see the mouth
- Teacher ok, that's working for us
- Teacher can we take pictures of these?
- Bugscope Team click to drive is hard to use
- Bugscope Team all of the images you see now are saved
- Bugscope Team for you in your school's database
- Teacher ok
- Bugscope Team http://bugscope.beckman.illinois.edu/members/2009-101/
- Teacher did we send in this specimen?
- Bugscope Team so the trick now is to drive around as much as you like and everywhere you go will be saved
- Bugscope Team pretty sure it was one you sent; Cate mounted them and I think she's on her way home now
- Bugscope Team you can see the Edge of the World here
- Teacher Do we have "visitors" that are watching us? Can they ask questions or comment?
- Bugscope Team there was a guest on who signed on as guest1, but she/he was silent
- Bugscope Team they can comment, ask questions
- Teacher When the kids get here in a few minutes, how do they log in?
- Bugscope Team sometimes we have to let them know that it is your session we're running
- Bugscope Team the kids should be able to log in to the Bugscope page -- the first page. and they should be able to select Student rather than Teacher
- Teacher Do our kids just go to the Bugscope website? Where do they go from there?
- Teacher ok
- Teacher We have 20 kids staying after school to do this -- they are excited!
- Bugscope Team the Bugscope website should read Lucky You on the right, and the software will recognize that the computers are from the same area as yours, so there should be no passwords now
- Bugscope Team Sounds great!
- Teacher We're ready and waiting for kids!
- Bugscope Team Cool. You may try any of the presets as well.
- Bugscope Team clicking on one of the presets will drive you to that location on the stub
- Teacher They may be tentative about asking questions -- maybe -- so you can tell them a few things about what they're seeing too.
- Bugscope Team if it was high mag, sometimes the sample will have moved a bit
- Bugscope Team hey no problem at all
- Teacher are these the feet?
- Bugscope Team these are the tiny sticky setae that help a ladybug or fly or other insect that has them walk on vertical surfaces
- Bugscope Team they are attached to the feet, usually
- Bugscope Team if you take the mag a little lower you may be able to see the claws
- Bugscope Team that *helps* them walk on vertical surfaces
- Bugscope Team you can see that the tips are spatulate
- Bugscope Team they're spread and sticky
- Bugscope Team at high mag here it doesn't look so good -- we see charging because the electrons are not able to go to ground quickly
- Teacher Are these surfaces oily? What makes them sticky?
- Teacher It may be a few minutes -- kids are here and are logging in.
- Bugscope Team one of the entomologists says they have chemicals on them that make them stick
- Bugscope Team like some kind of oil, yes.
- Bugscope Team Cate Mrs B asked if they had sent the DLL.
- Bugscope Team yes
- Bugscope Team Hi Bob, and Airborne, and Rosey, and Jordyn!
- Student Hi
- Student hi
- Bugscope Team All of the instects are theirs
- Bugscope Team and Grunt -- Hello!
- Student Hello
- Bugscope Team Hi guys!
- Student what am i looking at?
- Student What am i looking at?
- Bugscope Team this is part of the pulvillus on a ladybug's arm
- Student What is this?
- Student hi guys
- Bugscope Team it is a pad of sticky setae that help the ladybug cling to vertical surfaces
- Student is that feet?
Bugscope Team yes
- Student what is setae?
Bugscope Team Setae are basically bug hairs
- Student how many insects did you get?
Bugscope Team we got a lot of insects from you but could put only 10 or so on the stub
- Student is that bacteria on it?
Bugscope Team We didn't see any bacteria on it
- Student What is this?
Bugscope Team you can see one of the legs, the abdomen, the elytra, part of the wing
- Student What are we looking at?
Bugscope Team this is the ventrum -- the underside -- of the ladybug
- Student Do all bugs have hair?
Bugscope Team Yes, its how they sense whats around them
- Student why does it look stringy
- Teacher I am going to switch pictures to a daddy long legs
Bugscope Team Cool
- Student do you know how old the ladybug is?
- Student is this hair?
Bugscope Team the stuff that looks like hair is tiny setae
- Student how big is the claw
Bugscope Team the claw is maybe 200 microns long -- one fifth of a millimeter
- Student what is your favorite bug you got?
Bugscope Team today either the DLL or the wasp
- Student What are those flakes?
- Student What is the flakey stuff?
- Student what's the flaky stuff?
Bugscope Team Gunk
- Student is there hair on the claw?
- Student why is the claw so bumpy?
- Guest what is the claw for
Bugscope Team almost all insects and arthropods have claws
- Student is that a claw>
Bugscope Team yes this is a single claw at the end of the daddylonglegs arm
- Bugscope Team they are sort of like fingers would be to use
- Student What are those bumps
- Guest why does it have hair
Bugscope Team insects and other similar arthropods have exoskeletons, so it is like they are wearing armor. the setae help them sense their environment through that armor
- Bugscope Team like fingers would be to us, I should have said
- Student Is that just dirt on the base of the hair?
Bugscope Team Yup
- Teacher I'm switching do the daddy long legs pincers
- Teacher Is this the mouth or on the front legs?
Bugscope Team it feeds the mouth
- Student are tose claws?
Bugscope Team Yes
- Student what is that bump ?
- Student what are the bumps?
Bugscope Team the bumps make it harder to bite, harder to bend, tougher, and they also camouflage the body so it does not reflect brightly in the light
- Guest Are the pincers harmful to humans
- Teacher Do they use these pincers for picking things up? or for eating other insects?
- Student what do daddy long legs eat?
- Student Are these its legs
- Student Are daddy long legs carnivores?
- Student what are the long furry things
Bugscope Team those are palps, on either side of the claws
- Student What is all the area around the claws?
Bugscope Team this is the underside of the head, and it is hard for us to make out all of the features
- Teacher Let's look at the wasp compound eye.
- Guest I just joined. What are we looking at?
Bugscope Team that was a daddylonglegs
- Student is that an exoskeleton?
- Bugscope Team this is the edge of the compound eye of the wasp
- Student WHATS THE SPIKES
Bugscope Team Setae
- Bugscope Team to the right are ommatidia -- the eye facets
- Student Are those jsut little cuts on the eyes where it divits in the middle of an eye?
- Student Is this the bug with the spiked back?
- Student are those eyes?

- Student What is the ribbon thing?
Bugscope Team that is dust of some sort
- Student Whats the long tube
Bugscope Team above? that is one of the antennae
- Student how many insects cod you get?
- Bugscope Team now we are looking at one of the jaws
- Student Where is this on the wasp?
- Guest why are we looking at the eye what is the little hair for
- Bugscope Team the jaws open like a gate, from side to side
- Bugscope Team 8-10 insects on a stub
- Student Did you guys get the bug with the spiked back on here?
Bugscope Team that was an assassin bug.
- Guest what is on its face
Bugscope Team the jaws and mouth, the eyes, the antennae, the forehead, which I think is called a frons
- Bugscope Team I don't think it fit
- Student what do you do with the bugs you get when you're done/
Bugscope Team we pitch them
Bugscope Team We have to throw them away. They will start to rot otherwise.
- Student What happens to them then?
Bugscope Team they turn to dirt
- Bugscope Team sometimes we save insects that looked super cool, and we keep them in a desiccator to prevent them from rotting
- Teacher Let's look at the praying mantis head
- Student What is the coolest Bug youv'e had?
Bugscope Team I like earwigs, when they have mites, and I like mosquitos when you can see the mouthparts
- Student What is all the stringy stuff?
- Student Will you guys keep the assasin bug?
- Student Why are the eyes so big?
- Guest what is the zome on and why does it look so different
Bugscope Team Its on 44Xzzom right, you can see the magnification on the upper right corner

- Student How many eyes are in the Praying Mantis' compound eyes
Bugscope Team Thousands
- Teacher So, do they see thousands of images at once?
- Student how far can they see?
Bugscope Team probably a few feet with good clarity
- Student Do they have arms?
Bugscope Team praying mantises? yes. all insects have six legs as adults
- Student Why do they have ears on their legs?
Bugscope Team some insects do, like I think it is grasshoppers or certain crickets. they larger spaces for sensory structures that pick up sound
- Student Why does a lacewing have a lace wing anyway?
- Teacher Let's look at the lace wing.

- Student Why are hair called cetay?
- Student Are lace wings carnivores?
- Teacher If those setae break off, do they grow new ones?
- Student Do you know hany many bugs have stingers
Bugscope Team female insects have stingers. stingers are modified ovipositors, which are used to inject or lay eggs
- Student How does it breath and were do you mosty find them?
- Student How many Setae do you think are on the bug?
- Student Does this bug breathe through a mouth or the wholes?
- Bugscope Team lacewings are pretty tame as adults -- they eat things like nectar and pollen. but as larvae they are fierce insect predators
- Student What's the most bugs you ever got in one day?
- Teacher Let's go to the true bug spiracle.
- Student How many of those are on the bug?
- Student how many times to they magnify
- Student Why does this look like a tube?
Bugscope Team its the breathing tube
- Student what is inside the spiracle?
Bugscope Team the spiracle is one of the entrances to the tracheal system. it lets oxygen into the body
- Teacher So, do they breathe through this spiracle?
- Student How big is a spiricle?
- Student what are those bumps
- Student what are those bumps?
- Student why is it acurcle?
- Student Is this poky?
- Student where is it at
- Student What is a true bug?

- Student How many of those breathing holes are on the bug?
- Student Could a insect drown?
- Student Could this insect dround?
- Student could a bug dround?
Bugscope Team they can drown; they can also close their spiracles to hold their breath
- Student why is it so small ?
- Bugscope Team this is the side of the abdomen, and there will be another spiracle in the same position on the other side
- Student Could an inscet drown
Bugscope Team They need oxygen, so yes
- Student Can ticks drown?
- Student Could an insect sufficate if it's up-side down?
Bugscope Team nope
- Student do all bugs have spiracles on there legs
Bugscope Team I think they're all on the abdomen or on the thorax
- Teacher that is cool!
- Student How many spiracles do you think are on a bug?
Bugscope Team depends on the bug, but 20 to 30, maybe
- Student HOW DO THEY EAT?
Bugscope Team some insects bit and chew and swallow their food, some get it as a liquid through a straw-like proboscis

- Guest can it find some air in water if you put it in the water
- Student Dos this only let in oxygen or does it let anything else in the spriacle
- Student What fluid carries oxegen through the body?
Bugscope Team insects have hemolymph, but I am not sure that carries oxygen
- Student What started this "bugscope" idea?
Bugscope Team we wanted to be able to run a sustainable outreach program, and this turned out to be a lot of fun
- Teacher We're switching to the moth scales.

Bugscope Team yes they do, and they sometimes have different colors, both structural colors and actual pigment colors
- Guest are the scales thin as paper
- Student Does the scales help moths fly?
- Student is there powder on the scales
Bugscope Team the scales are what feels like powder when you rub a butterfly's wings
- Student what happens if there is a bare spot?
- Student what happens when scales are removed
- Student why are they all crooked?
- Student Are scales more vulnerable for bacteria or death in one spot?
- Student So does that make them more valurable for virus or bacteria to affect them?

Bugscope Team yes
- Bugscope Team feathers
- Guest do they died after a big number of scales are off
Bugscope Team yes they may die if they lose a lot of scales
- Student Is this a moth?
- Teacher Why are these pictures in black and white? Do electron microscopes ever capture pictures in color?
Bugscope Team electron microscopes capture images as signal, and the images come from the secondary electrons, usually
Bugscope Team It uses electrons instead of photons, so they're all in black and white
- Student why is there lines?
- Student what is that spot?
- Student Is it always completely straight?
- Student what are those lines
Bugscope Team bob7 those are the ridges of the scale
- Student How much does a electron microscope caot?

Bugscope Team because it is
- Student how much does your microscope cost ?
Bugscope Team about $600,000 10 years ago
- Student what is the rope thing?
- Student Do spiders have stingers?
Bugscope Team no they have fangs. they inject venom that dissolves the inside of their prey, and they suck that all up like a milkshake
- Student How much do electron microspopes cost now?
- Student can you see atoms with these microscopes?
- Teacher I"m having trouble changing presets? I see Warning: You're probably at the max or min of that control
Bugscope Team let me see if it works for me
- Student Have you ever got a goliath taranula?
- Student can you see electrons, protons,& neutrons?
Bugscope Team no
- Student Do they drink blood?
- Guest are there cells in the scales

- Student are they born with the scales?
- Student How many much can an electrion microscope magnifie?
- Student how many scales are there ?
- Student What are the egg things
- Student why is the spider so hairy
Bugscope Team those hairs help the spider to feel its environment
- Student is that an exoskeleton?
- Student are those hairs
Bugscope Team those hairs are called setae (see-tee) and they help insects to sense their environment
- Teacher So this is the underside of a large spider!
- Student How do spiders get rid of waste/
Bugscope Team like people, in a way. but they can recycle their web by eating it

- Student Yuck a bloody milkshake
- Student do they bite their victim?
- Student how do they bite there victim
- Student how many kinds of spiders are there?
Bugscope Team there are about 40,000 different species of spiders! wow!
