- Bugscope TeamCool DaddyO.
- 12:06 pm
- 12:14 pm
- Bugscope Teamwhoa that looks like an assassin bug.
- 12:19 pm
- 12:24 pm
- 12:29 pm
- Bugscope Teampresets are done, session unlocked. we are ready!
- Bugscope Teamthis is the fly, where I thought the haltere would be
- 12:34 pm
- Bugscope Teammore pollen
- Bugscope Teamthis is the haltere I think but it is collapsed to the big time
- 12:40 pm
- Bugscope Teammaking the tenent setae straighten up with the electron beam
- 12:45 pm
- 12:50 pm
- Bugscope TeamHello Mrs C!
- Bugscope Teamwelcome to bugscope
- Bugscope TeamI was driving and didn't notice you were on for a sec.
- Bugscope Teamhey Mrs. Coltharp
- Bugscope Teamif you need instructions on how to increase the screen res, just let me know. i can run you through it.
- 12:58 pm
- Bugscope Teamthis is the assassin bug, which was mangled on one end
- Bugscope Teamthis is the good end -- the head
- Bugscope Teamh'lo Chas
- TeacherHi! 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 Teamtry expanding your browser window. or increasing the screen resolution. if you are running at 800x600, it won't work well at all.
- Bugscope TeamF5 should maximize your browser window
- Bugscope Teamif you are using IE that is
- 1:03 pm
- Bugscope TeamF11, yes, F11, not F5. F5 is refresh
- TeacherThanks! We are ready to go!
- Bugscope Teamawesome
- Bugscope TeamGreat!
- Bugscope TeamYay!
- TeacherShould I currently have control of the microscope because I don't see the controls like I did on Tuesday
- Bugscope Teammrs. C you should also see presets on your lower right.
- Bugscope Teamyou can click on a preset to take you to interesting locations.
- TeacherI don't see the presets either.
- Bugscope Teamon the top right, you should see the microscope controls, magnify, navigation, focus and adjust
- Bugscope TeamControls labelled "Magnify", "Navigation" etc should show up to the right side of the image
- Bugscope Teamtry hitting F5
- Bugscope Teamfor refresh
- Bugscope Teammrs. C, have you checked your screen resolution? do you need me to run you through how to do that?
- Bugscope TeamMrs. 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?
- GuestHi I'm Catherine Kimbles Grandma in Phoenix
- Bugscope TeamGlad to have you with us mew, we're just getting going here
- TeacherMr. Harrell, our hero, just fixed it! Hi, Catherin'es Grandma! How cool is that!
Bugscope TeamGreat to hear! Let us know if you have any questions about how to use the controls
- Bugscope TeamHi mew!
- Bugscope Teamcoolness
- Bugscope Teami wish were in phoenix!
- Bugscope TeamWelcome to bugscope.
- Guestthank you are you a student in class
- Bugscope TeamThis is the eye of the assassin bug.
- 1:08 pm
- Bugscope Teammew all of us in green are the bugscope team, at the University of Illinois
- TeacherWhat is the thread on his eye? Or the splotch of stuff at the top left?
Bugscope TeamThat is dirt and dusty stuff
- Bugscope Teamwe are here to help, and to answer questions
- Bugscope Teamit's a little piece of web, perhaps
- Bugscope Teamit may also be part of a strand of fungus
- Bugscope Teamthis is pretty much one single facet of the eye -- a single facet is called an ommatidium.
- Bugscope Teamremember that you can tune the focus up when you get close and it does not quite look perfect
- TeacherWould we be able to see the spiracles on the assassin bug?
- Bugscope Teamassassin bugs eat other bugs
- Bugscope Teamif you take the mag down and go to the SW
- Bugscope TeamI think you will be able to see -- yeah there is one
- Bugscope Teamyou can click to center,
- Bugscope Teamlike that -- you are almost right on it if you take the mag up
- Bugscope Teamgood job controlling the scope mrs. C!
- TeacherWhich one is a spiracle, the big hole or the three small ones?
Bugscope TeamThe smaller three, I believe. Annie?
- Bugscope Teamthe small ones
- Bugscope Teamthere is also one on the thorax
- 1:14 pm
- Bugscope Teaminsects can close their spiracles if they want to hold their breath for a little while
- Bugscope TeamTake a look at the scale bar right now. You can see the spiracle is roughly 60um wide, about the width of human hair
- Bugscope TeamThis would be a great place to try out the focus control
- Bugscope Teamand often they have tiny setae outside them to protect them from dust getting in
- Bugscope Teamnice
- Bugscope Teamgood driving
- Bugscope Teamlooks great
- Bugscope Teamoooh
- Bugscope TeamWow, very cool!
- Bugscope TeamWhat a beautiful image, no charging even
- Bugscope Teamyeah that is so nice
- TeacherThis is awesome!
- Bugscope Team10 micrometers is ten bacteria long
- Bugscope Teamoops I mean five
- Bugscope Teamspiracles are connected to trachaea---that are connected to smaller and smaller tracheoles. The tracheal systems is analogous to our lungs
- Bugscope Teamfive bacteria long
- Bugscope TeamI wonder if those have a similar function to the hairs in your nose; to filter out particulate matter from the air?
Bugscope Teamthats what i was thinking
- TeacherWe were just wondering the same thing!
- Bugscope Teamso we would be able to see bacteria if there were any here
- Bugscope Teamheh spiracle boogers
- Bugscope TeamEach 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 Teamyou can see another one -- oval -- to the right, on the thorax
- Bugscope Teamthe dragonfly face
- Bugscope Teamalmost all eyes
- Bugscope Teamhead not dead
- 1:19 pm
- Bugscope TeamTheir 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 Teamyeah you can barely see where the jaws are
- Bugscope Teamyou can see on either side of the
- Bugscope Teamlet me try that again
- TeacherWhat are the holes next to his nose?
Bugscope TeamIt looks like the base where something broke off from
- Bugscope Teamantennae
- Bugscope Teamyou can see the base of the antennae in the middle of the screen here
- Bugscope Teamthey are the bases of antennae -- part is busted off
- Bugscope Teamvery fragile
- Bugscope Teamthe terminal segment of the antenna is broken...DOH
- Bugscope TeamCOOL
- Bugscope Teamwow, 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 TeamThese are great images
- Bugscope Teamwhen we look at dragonfly heads, almost always the antennae broke off.
- Bugscope Teamthe inside of this one is charging up with electrons
- TeacherThanks! I needed to hear that today!
- Bugscope Teamthat is why it brightened up
- TeacherWhat are the small holes used for?
Bugscope TeamThat'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 TeamMaybe Annie knows about the small holes...
- Bugscope Teamdragonflies 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 TeamI think the small holes are just cross section of the musculature that used to be connected to the tip of the antenna
- Bugscope Teamwhy it busted -- 'cause it was weak
- TeacherThat's a pretty picture!
Bugscope Teamall 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 Teamnow you can see the ommatidia
- 1:24 pm
- Bugscope Teamchat is also saved on your member page
- TeacherPlease tell us what that is!
Bugscope Teaman ommatidium is an individual facet of the compound eye
- Bugscope Teamwhen these are broken -- when the eye is broken -- you can see that these are crystalline
- Bugscope Teamthe hexagons are the individual facets of the compound eye
- Bugscope Teamthere is a good image of a compound eye of a fruit fly in the presets
- Bugscope Teamsometimes insects will have setae in between the ommatidia
- Bugscope Teamlike this one
- Bugscope Teamso here we have a different looking compound eye
- TeacherWhy do they have the setae in their eye?
Bugscope Teamthese setae are thought to help the insect detect changed in wind currents
- Bugscope Teamthe ommatidia are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.
- Bugscope Teamthese setae have a mechanosensory function
- Bugscope Teamthey can feel the movement of the wind
- TeacherThat's amazing!
- Bugscope Teamthe eyes on the fruit fly are very large, meaning that they rely on their eyes a lot
- Bugscope Teamyou 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 Teamif 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
- 1:29 pm
- Bugscope Teamnow we are on the mouth
- Bugscope TeamHello Phoebe's Dad!
- TeacherHi, Phoebe's Dad! Great to have you!
- Bugscope TeamThese guys like fruit juice -- this is the mouth of the fruit fly.
- TeacherIs this the part they use to sponge up the food or is it another part?
- Bugscope Teamthis is the part
- Bugscope Teamit is a little dry and wrinkled compared to what it is like when the little dude is alive
- Bugscope TeamFruit flies often feed on yeasts that live on rotting fruit...not on the fruit itself
- Bugscope Teamthe little setae here (the hairs) are also probably sensory
- Bugscope TeamAnnie makes sure we stay straight
- TeacherIs there any part of an insect that isn't covered with setae?
Bugscope TeamDepends upon the insect...some beetles have very smooth areas with few or no setae
- Bugscope Teamwe could go look
- Bugscope Teamsometimes on the other side -- the side we usually mount down -- there are few setae
- Bugscope Teamlike on a beetle elytra
- Bugscope Teamelytrum
- Bugscope Teambut this is pretty hairy isn't it?
- Bugscope Teamelytra are hardenned forwings on certain insects, mostly beetles
- TeacherIs this an antennae
- Bugscope Teamthis is one of the antennae, at the top left
- Bugscope Teamyes
- 1:34 pm
- Bugscope Teamright there
- Bugscope Teamelytra are also called shardes...
- TeacherA student asks - Is his whole antennae just hair? Are all insect antennae like that?
Bugscope Teamyou can see the fly anntenna in the middle of the head. They are fleshy and short...and covered wtih short setae
- Bugscope Teamthe 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 Teamsome chemosensory setae are set up to sense one chemical in the air, and some are capable of sensing multiple chemical smells
- Bugscope TeamI wonder if they can smell ethylene oxide when bananas start to ripen
- Bugscope Teampollen, or sometimes those are mode spores
- Bugscope Teammold*
- Bugscope Teamnow we are looking at a spiracle again. but with protection
- Bugscope Teamyeah mold spores'
- Bugscope Teamsheesh
- TeacherWhat is the big white spot?
- Bugscope Teamjuju
- TeacherDo I want to know what juju is?
- Bugscope Teamit is a piece of debris the setae caught
- Bugscope Teamit's a piece of dust that got held back from going into the spiracle by the setae
- 1:39 pm
- TeacherThank goodness!
- Bugscope Teamsetae doing it's job!
- Bugscope Teamjuju is just, like, stuff
- TeacherThat's cool!
- Bugscope Teamthe haltere is to the upper right
- Bugscope Teamnow we are right on the wing
- Bugscope Teamand the haltere is out of the image
- TeacherMy students REALLY want to see the wing
- TeacherAre the holes where the fly had hairs that fell out?
Bugscope Teamyes I believe so
- Guestwow
- Guestcool huh'
- 1:44 pm
- Bugscope Teamhello icantos!
- TeacherAre these the ant mandibles?
- Bugscope Teamhere are the ant mandibles
- Bugscope Teamthis looks like the mouth of the flying ant
- Bugscope Teamd'oh.....
- Bugscope Teamthey often have "busy" looking mouths; like they were in the process of eating something
- Bugscope Teamjaws
- TeacherWhat is chemical that makes an ant bite sting?
- Bugscope Teamformic acid
- TeacherWhat part of the mouth produces that? Do they have a special organ?
Bugscope TeamAnts defend themselves in several ways. Some spray formic acid from their abdomens, some sting just like a wasp, and some bite.
- TeacherDo both male and female ants bite?
Bugscope TeamYou 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
- 1:49 pm
- Bugscope TeamThey do have special organs that produce the formic acid
- Bugscope TeamMrs C when we are slow to answer it's because Annie is the expert and we are shifting the burden to her.
- Bugscope Teamthis is cool
- Guesthi man
- TeacherWe'd like to see if the ant's antennae are as hairy as the fly's
Bugscope Teamwell comparatively, they look a lot different, ants have a lot longer antennae
- Bugscope TeamHi Zarth.
- Guestwat up icantos
- Bugscope Teamwhen I don't answer quickly I am writing out some long, over-involved answer
- Guestzath man
- Bugscope TeamAnnie was pausing for breath
- Guestya haha
- Bugscope Teamhaha
- Guestweard
- Bugscope Teamlooks cute
- Guestal rite cool huh
- Guestthat's way cool
- Bugscope Teamtarsomeres
- 1:54 pm
- Guestya
- TeacherWhat are the spikes on his joints?
Bugscope TeamThose are tibial spurs. The insect can use them to stick to surfaces or to defend themselves
- Guestthats a leg off an ant!!!!!!
- Bugscope Teamthe spikes make it so that the insect can feel if it is overextending its joint
- TeacherThat's amazing!
- Bugscope Teamif they bend too far in the wrong direction they get a little sting
- Bugscope TeamI didnt know that
- TeacherWow! What are the spikes on the Dragonfly wing???
Bugscope TeamI am not sure if we know what they do....
- Bugscope Teamooh busted
- Guestway weard man!!!!!!!!!!
- Bugscope Teambut you know Martin is the one who told me about the spikes
- Bugscope Teamyou've stumped me
- Guestya WOW huh
- Guestcooooool
- Bugscope Teamthe end of the proboscis is at the bottom
- Bugscope Teamtest
- Guesti know man WOW cool huh
- Bugscope Teammosquito head
- Bugscope Teamall eyes
- Guestme and icantos are friends right man
- TeacherWOW!!!
- Guestrite
- Bugscope Teamuh pulvillus
- 1:59 pm
- Bugscope Teamand claws
- Guestwat is that
- Bugscope Teamthe pulvillus is the sitcky pad that some insects have on the tarsi
- Bugscope TeamThis is an insect foot
- Bugscope TeamThank You!
- Guestthanks man bye
- Guestthanks
- Bugscope TeamThank you!
- Guestbye bye from phoenix
- Bugscope TeamBye!
- Bugscope TeamThank You!
- Guestthank you!
- Bugscope Teamchow! thank you!
- Guestdece are you there
- Bugscope TeamCiao!
- Guestyeah but I've got to run
- 2:05 pm
- Bugscope TeamPhoebe's Dad let us know if you want to drive a bit.
- Bugscope Teamover and out for me
- Bugscope Teamokay, real good session folks. i'm disabling the session now, shutting down rxl...
- 2:10 pm
- Bugscope Teamokay, rxl stopped, session disabled. forcing out remaining users now, and will close the session.
- Bugscope Teamwhee
- Bugscope Teami'm logging out
