- 12:14pm

- Bugscope Team whoa that looks like an assassin bug.
- 12:19pm


- 12:24pm



- 12:29pm

- Bugscope Team presets are done, session unlocked. we are ready!

































- Bugscope Team this is the fly, where I thought the haltere would be
- 12:34pm














- Bugscope Team more pollen
- Bugscope Team this is the haltere I think but it is collapsed to the big time




















- 12:40pm
























- Bugscope Team making the tenent setae straighten up with the electron beam












- 12:45pm

















































- 12:50pm

















- Bugscope Team Hello Mrs C!
- Bugscope Team welcome to bugscope
- Bugscope Team I was driving and didn't notice you were on for a sec.
- Bugscope Team hey Mrs. Coltharp




- Bugscope Team if you need instructions on how to increase the screen res, just let me know. i can run you through it.
- 12:58pm




- Bugscope Team this is the assassin bug, which was mangled on one end
- Bugscope Team this is the good end -- the head
- Bugscope Team h'lo Chas
- Teacher Hi! Currently I don't have the picture showing so that I can type and show the picture at the same time. Do you know how I can fix that?
Bugscope Team try expanding your browser window. or increasing the screen resolution. if you are running at 800x600, it won't work well at all.
- Bugscope Team F5 should maximize your browser window
- Bugscope Team if you are using IE that is
- 1:03pm
- Bugscope Team F11, yes, F11, not F5. F5 is refresh
- Teacher Thanks! We are ready to go!
- Bugscope Team awesome
- Bugscope Team Great!
- Bugscope Team Yay!
- Teacher Should I currently have control of the microscope because I don't see the controls like I did on Tuesday
- Bugscope Team mrs. C you should also see presets on your lower right.
- Bugscope Team you can click on a preset to take you to interesting locations.
- Teacher I don't see the presets either.
- Bugscope Team on the top right, you should see the microscope controls, magnify, navigation, focus and adjust
- Bugscope Team Controls labelled "Magnify", "Navigation" etc should show up to the right side of the image
- Bugscope Team try hitting F5
- Bugscope Team for refresh
- Bugscope Team mrs. C, have you checked your screen resolution? do you need me to run you through how to do that?
- Bugscope Team Mrs. Coltharp: Is your screen too small such that the microscope image goes all the way to the right side of your browser window, or is there a blank dark-grey space to the right?
- Guest Hi I'm Catherine Kimbles Grandma in Phoenix
- Bugscope Team Glad to have you with us mew, we're just getting going here
- Teacher Mr. Harrell, our hero, just fixed it! Hi, Catherin'es Grandma! How cool is that!
Bugscope Team Great to hear! Let us know if you have any questions about how to use the controls
- Bugscope Team Hi mew!
- Bugscope Team coolness
- Bugscope Team i wish were in phoenix!

- Bugscope Team Welcome to bugscope.


- Guest thank you are you a student in class

- Bugscope Team This is the eye of the assassin bug.

- 1:08pm
- Bugscope Team mew all of us in green are the bugscope team, at the University of Illinois
- Teacher What is the thread on his eye? Or the splotch of stuff at the top left?
Bugscope Team That is dirt and dusty stuff
- Bugscope Team we are here to help, and to answer questions

- Bugscope Team it's a little piece of web, perhaps

- Bugscope Team it may also be part of a strand of fungus

- Bugscope Team this is pretty much one single facet of the eye -- a single facet is called an ommatidium.






- Bugscope Team remember that you can tune the focus up when you get close and it does not quite look perfect
- Teacher Would we be able to see the spiracles on the assassin bug?
- Bugscope Team assassin bugs eat other bugs
- Bugscope Team if you take the mag down and go to the SW



- Bugscope Team I think you will be able to see -- yeah there is one

- Bugscope Team you can click to center,
- Bugscope Team like that -- you are almost right on it if you take the mag up

- Bugscope Team good job controlling the scope mrs. C!
- Teacher Which one is a spiracle, the big hole or the three small ones?
Bugscope Team The smaller three, I believe. Annie?
- Bugscope Team the small ones



- Bugscope Team there is also one on the thorax



- 1:14pm
- Bugscope Team insects can close their spiracles if they want to hold their breath for a little while



- Bugscope Team Take a look at the scale bar right now. You can see the spiracle is roughly 60um wide, about the width of human hair
- Bugscope Team This would be a great place to try out the focus control
- Bugscope Team and often they have tiny setae outside them to protect them from dust getting in
- Bugscope Team nice
- Bugscope Team good driving
- Bugscope Team looks great

- Bugscope Team oooh

- Bugscope Team Wow, very cool!
- Bugscope Team What a beautiful image, no charging even
- Bugscope Team yeah that is so nice

- Teacher This is awesome!
- Bugscope Team 10 micrometers is ten bacteria long
- Bugscope Team oops I mean five

- Bugscope Team spiracles are connected to trachaea---that are connected to smaller and smaller tracheoles. The tracheal systems is analogous to our lungs
- Bugscope Team five bacteria long
- Bugscope Team I wonder if those have a similar function to the hairs in your nose; to filter out particulate matter from the air?
Bugscope Team thats what i was thinking
- Teacher We were just wondering the same thing!


- Bugscope Team so we would be able to see bacteria if there were any here

- Bugscope Team heh spiracle boogers



- Bugscope Team Each cell in an insect body has to be close enough to a tracheole to supply the cell with oxygen. Insect blood does not carry oxygen like ours does.




- Bugscope Team you can see another one -- oval -- to the right, on the thorax

- Bugscope Team the dragonfly face

- Bugscope Team almost all eyes

- Bugscope Team head not dead
- 1:19pm

- Bugscope Team Their more primitive respiratory system is one of the main factors limiting their size. The supply of air doesn't scale the same as the body size, so the oxygen level in the air is essentially limiting them from growing to huge sizes

- Bugscope Team yeah you can barely see where the jaws are

- Bugscope Team you can see on either side of the

- Bugscope Team let me try that again
- Teacher What are the holes next to his nose?
Bugscope Team It looks like the base where something broke off from

- Bugscope Team antennae
- Bugscope Team you can see the base of the antennae in the middle of the screen here


- Bugscope Team they are the bases of antennae -- part is busted off

- Bugscope Team very fragile
- Bugscope Team the terminal segment of the antenna is broken...DOH



- Bugscope Team COOL
- Bugscope Team wow, mrs. C, you are controlling the scope like an expert. no doubt you are one of the top 10 scope drivers of the recent past...
- Bugscope Team These are great images
- Bugscope Team when we look at dragonfly heads, almost always the antennae broke off.
- Bugscope Team the inside of this one is charging up with electrons
- Teacher Thanks! I needed to hear that today!
- Bugscope Team that is why it brightened up
- Teacher What are the small holes used for?
Bugscope Team That's probably just a cross-section of the internal structure. Sort of like if you look at cardboard from the side, it's corrugated to save weight while maintaining strength

- Bugscope Team Maybe Annie knows about the small holes...
- Bugscope Team dragonflies rely on sight to locate their prey and to locate each other...that is one of the reasons that they have such small antennae
- Bugscope Team I think the small holes are just cross section of the musculature that used to be connected to the tip of the antenna



- Bugscope Team why it busted -- 'cause it was weak

- Teacher That's a pretty picture!
Bugscope Team all images are saved on your member page, which you can access as soon as your session is done, or now even, at: http://bugscope.beckman.uiuc.edu/members/2007-068





- Bugscope Team now you can see the ommatidia

- 1:24pm
- Bugscope Team chat is also saved on your member page
- Teacher Please tell us what that is!
Bugscope Team an ommatidium is an individual facet of the compound eye


- Bugscope Team when these are broken -- when the eye is broken -- you can see that these are crystalline



- Bugscope Team the hexagons are the individual facets of the compound eye

- Bugscope Team there is a good image of a compound eye of a fruit fly in the presets

- Bugscope Team sometimes insects will have setae in between the ommatidia
- Bugscope Team like this one
- Bugscope Team so here we have a different looking compound eye
- Teacher Why do they have the setae in their eye?
Bugscope Team these setae are thought to help the insect detect changed in wind currents
- Bugscope Team the ommatidia are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.
- Bugscope Team these setae have a mechanosensory function
- Bugscope Team they can feel the movement of the wind
- Teacher That's amazing!






- Bugscope Team the eyes on the fruit fly are very large, meaning that they rely on their eyes a lot


- Bugscope Team you can tell by their shape and by the pore they are sticking out of that they are made to bend slightly as well as send the information about them moving to nerves inside of the head






- Bugscope Team if you were to see the fruit fly brain in cross section you could tell that a huge percentage of the brain is devoted to processing visual information
- 1:29pm

- Bugscope Team now we are on the mouth

- Bugscope Team Hello Phoebe's Dad!

- Teacher Hi, Phoebe's Dad! Great to have you!
- Bugscope Team These guys like fruit juice -- this is the mouth of the fruit fly.
- Teacher Is this the part they use to sponge up the food or is it another part?
- Bugscope Team this is the part


- Bugscope Team it is a little dry and wrinkled compared to what it is like when the little dude is alive
- Bugscope Team Fruit flies often feed on yeasts that live on rotting fruit...not on the fruit itself
- Bugscope Team the little setae here (the hairs) are also probably sensory


- Bugscope Team Annie makes sure we stay straight

- Teacher Is there any part of an insect that isn't covered with setae?
Bugscope Team Depends upon the insect...some beetles have very smooth areas with few or no setae



- Bugscope Team we could go look




- Bugscope Team sometimes on the other side -- the side we usually mount down -- there are few setae
- Bugscope Team like on a beetle elytra

- Bugscope Team elytrum
- Bugscope Team but this is pretty hairy isn't it?


- Bugscope Team elytra are hardenned forwings on certain insects, mostly beetles
- Teacher Is this an antennae

- Bugscope Team this is one of the antennae, at the top left
- Bugscope Team yes

- 1:34pm
- Bugscope Team right there
- Bugscope Team elytra are also called shardes...

- Teacher A student asks - Is his whole antennae just hair? Are all insect antennae like that?
Bugscope Team you can see the fly anntenna in the middle of the head. They are fleshy and short...and covered wtih short setae



- Bugscope Team the setae are what helps the insect to feel and sense and to know what is going on. They have to constantly know what is happening....what is coming at them from all sides.

- Bugscope Team some chemosensory setae are set up to sense one chemical in the air, and some are capable of sensing multiple chemical smells

- Bugscope Team I wonder if they can smell ethylene oxide when bananas start to ripen

- Bugscope Team pollen, or sometimes those are mode spores

- Bugscope Team mold*

- Bugscope Team now we are looking at a spiracle again. but with protection

- Bugscope Team yeah mold spores'
- Bugscope Team sheesh
- Teacher What is the big white spot?
- Bugscope Team juju
- Teacher Do I want to know what juju is?
- Bugscope Team it is a piece of debris the setae caught
- Bugscope Team it's a piece of dust that got held back from going into the spiracle by the setae
- 1:39pm
- Teacher Thank goodness!
- Bugscope Team setae doing it's job!
- Bugscope Team juju is just, like, stuff
- Teacher That's cool!











- Bugscope Team the haltere is to the upper right

- Bugscope Team now we are right on the wing

- Bugscope Team and the haltere is out of the image


- Teacher My students REALLY want to see the wing


- Teacher Are the holes where the fly had hairs that fell out?
Bugscope Team yes I believe so
- Guest wow

- Guest cool huh'





- 1:44pm





- Bugscope Team hello icantos!
- Teacher Are these the ant mandibles?
- Bugscope Team here are the ant mandibles
- Bugscope Team this looks like the mouth of the flying ant
- Bugscope Team d'oh.....
- Bugscope Team they often have "busy" looking mouths; like they were in the process of eating something

- Bugscope Team jaws
- Teacher What is chemical that makes an ant bite sting?

- Bugscope Team formic acid
- Teacher What part of the mouth produces that? Do they have a special organ?
Bugscope Team Ants defend themselves in several ways. Some spray formic acid from their abdomens, some sting just like a wasp, and some bite.








- Teacher Do both male and female ants bite?
Bugscope Team You very rarely see male ants. They are typically only produced by a colony once per year. I imagine that male ants can bite...but since they are less frequently encountered , they probably bite less overall
- 1:49pm

- Bugscope Team They do have special organs that produce the formic acid




- Bugscope Team Mrs C when we are slow to answer it's because Annie is the expert and we are shifting the burden to her.

- Bugscope Team this is cool

- Guest hi man
- Teacher We'd like to see if the ant's antennae are as hairy as the fly's
Bugscope Team well comparatively, they look a lot different, ants have a lot longer antennae

- Bugscope Team Hi Zarth.

- Guest wat up icantos
- Bugscope Team when I don't answer quickly I am writing out some long, over-involved answer

- Guest zath man

- Bugscope Team Annie was pausing for breath
- Guest ya haha


- Bugscope Team haha



- Guest weard


- Bugscope Team looks cute





- Guest al rite cool huh


- Guest that's way cool
- Bugscope Team tarsomeres
- 1:54pm
- Guest ya
- Teacher What are the spikes on his joints?
Bugscope Team Those are tibial spurs. The insect can use them to stick to surfaces or to defend themselves
- Guest thats a leg off an ant!!!!!!
- Bugscope Team the spikes make it so that the insect can feel if it is overextending its joint
- Teacher That's amazing!
- Bugscope Team if they bend too far in the wrong direction they get a little sting
- Bugscope Team I didnt know that

- Teacher Wow! What are the spikes on the Dragonfly wing???
Bugscope Team I am not sure if we know what they do....
- Bugscope Team ooh busted
- Guest way weard man!!!!!!!!!!
- Bugscope Team but you know Martin is the one who told me about the spikes

- Bugscope Team you've stumped me
- Guest ya WOW huh
- Guest cooooool
- Bugscope Team the end of the proboscis is at the bottom
- Bugscope Team test
- Guest i know man WOW cool huh


- Bugscope Team mosquito head
- Bugscope Team all eyes

- Guest me and icantos are friends right man
- Teacher WOW!!!
- Guest rite
- Bugscope Team uh pulvillus
- 1:59pm
- Bugscope Team and claws
- Guest wat is that
- Bugscope Team the pulvillus is the sitcky pad that some insects have on the tarsi
- Bugscope Team This is an insect foot
- Bugscope Team Thank You!
- Guest thanks man bye
- Guest thanks
- Bugscope Team Thank you!
- Guest bye bye from phoenix
- Bugscope Team Bye!
- Bugscope Team Thank You!
- Guest thank you!
- Bugscope Team chow! thank you!
- Guest dece are you there
- Bugscope Team Ciao!
- Guest yeah but I've got to run
- 2:05pm
- Bugscope Team Phoebe's Dad let us know if you want to drive a bit.
- Bugscope Team over and out for me
- Bugscope Team okay, real good session folks. i'm disabling the session now, shutting down rxl...
- 2:10pm
- Bugscope Team okay, rxl stopped, session disabled. forcing out remaining users now, and will close the session.
- Bugscope Team whee
- Bugscope Team i'm logging out
- Bugscope Team laterz
