- 1:12pm
- Bugscope Team we took out the sample and are going to put a wasp on it and put it in the chamber again. it should be pumped soon and we can make the presets
- 1:26pm
- 1:31pm
- 1:36pm
- 1:41pm
- Bugscope Team all right we are ready on our end
- Bugscope Team Col Chas!
- Bugscope Team The problem we had resolved itself, in a way
- Teacher hey! whats up were here!
- Bugscope Team yay!
- Bugscope Team we don't know what a couple of these guys are
- 1:47pm
- Teacher how do i make this full screen
- Bugscope Team F5
- Bugscope Team ok ms. clark, so you know how it works. Two of your samples are on here-- the potter wasp and the housefly
- Bugscope Team From a Windows PC you should be able to hit F11
- Bugscope Team F11
- Bugscope Team F5 refreshes I think
- Bugscope Team yeah sorry wasn't thinkin'
- Teacher is this the house fly?
- Bugscope Team this is a borer of some sort
- Bugscope Team perhaps
- Bugscope Team no this is some sort of borer that was brought in to us
- Bugscope Team the housefly can be found at preset 4
- Bugscope Team compound eye
- Bugscope Team if you have compound eyes you have a high refresh rate and can see changes in your visual field very quickly
- Teacher what are the hairs coming out of the eye
Bugscope Team those are hairs, which when we find them on insects are called setae or for one hair- seta
- Bugscope Team keeps you from getting smacked
- Teacher hahahahahahaha
- Bugscope Team see-tee
- Bugscope Team in fruit flies the setae between the ommatidia are used to gauge windspeed
- Bugscope Team ommatidia are the facets of the eye
- 1:52pm
- Bugscope Team nice mouthparts
- Teacher how does the mouth work?
- Bugscope Team we were thinking this was some kind of borer, and the middle things we see now look like powerful jaws
- Bugscope Team but we are not sure what this is
- Bugscope Team if you go a little closer maybe we can make out some more of the structure
- Bugscope Team hard to tell -- we will have to ask Annie what that was
- Teacher what is this?
- Bugscope Team this is another insect that was brought in with the "borer". It is another mystery bug
- Bugscope Team well -- sorry but this was the other mystery bug -- a beetle
- Bugscope Team it has a pretty big muscley-looking head
- Bugscope Team yeah 'cause we don't think it is particularly smart
- Bugscope Team what we see is one of the jaws, and the thing that looks like a bat is one of the palps
- Teacher how does the mouth work?
- 1:57pm
- Bugscope Team palps are mouthparts that taste and manipulate food
- Bugscope Team in this case the jaws open and close like little gate hinges
- Teacher is the mouth broken?
- Bugscope Team maybe a little
- Bugscope Team it looks like the top part is chipped
- Teacher how much was this microscope/
- Bugscope Team about $600,000
- Bugscope Team and that was about 10 years ago
- Bugscope Team it is very nice
- Teacher it better be nice if it costs that much
- Bugscope Team it can do a lot of things we don't see now
- Bugscope Team like elemental analysis
- Teacher is that the eye or the antennae?
Bugscope Team it is both. there is a section of the antenna that is partially broken and the compound eye is right behind it
- Bugscope Team that is the antenna
- Bugscope Team with the eye behind it
- Teacher why is the antannae infrnt of the eye?
- Bugscope Team maybe because the antenna is more important to the insect
- Bugscope Team yeah it wouldn't be able to see to well in front with something blocking the way one would think
- Teacher what do the hairs do?
- 2:02pm
- Bugscope Team the hairs are often sensory
- Bugscope Team some are chemo- and some are mechanosensory
- Bugscope Team owlfly larva
- Bugscope Team this is one of the little claws
- Teacher can we break it?
- Bugscope Team owlflies are predatory
- Bugscope Team break the microscope?
- Bugscope Team no
- Bugscope Team we set it up so that there is little that can be done from a distance to cause problems
- Bugscope Team the larvae are predatory too. they are related to antlions
- Bugscope Team they are kind of mean, like dragonflies
- Teacher what do all the hairs do?
- Teacher and why are they there
- 2:07pm
- Bugscope Team hairs generally have a sensory purpose like cat or rat whiskers
- Bugscope Team it could serve the purpose of keeping away bigger insects (like why caterpillars are so hairy), but it could also be like trigger hairs that will make the jaws snap on the insect that is near it
- Bugscope Team so they would not be able to feel their environment if they did not have tiny hairs (setae) sticking through the exoskeleton
- Bugscope Team this is really cool
- Teacher why does it look like a fish?
- Bugscope Team you rarely get to see the bare stylet
- Bugscope Team it loks like a moray eel to me
- Bugscope Team that is the business end of the mosquito's proboscis
- Teacher what is a styilet?
- Bugscope Team this was a mosquito that i squished :)
- Bugscope Team the reason we could see it is because Cate smashed the daylights out of it
- Bugscope Team the stylet is the part that pierces
- Bugscope Team that's why it had little barbs on it like a stinger
- Bugscope Team so now we are looking at a Gary Larsen cartoon
- Bugscope Team yeah the little barbs help it cut into the skin like serrations on a steak knife
- 2:13pm
- Guest hello
- Bugscope Team Hi Maria!
- Bugscope Team this is back to the owlfly larva. this has a very simple looking claw
- Bugscope Team we also have a preset for the wasp claw so you can compare if you want
- Teacher why does a larva need to have claws
- Bugscope Team Mrs Phelps we are working with a school in Mahomet IL
- Bugscope Team they make it able to grasp onto things so it can get around and also position what it might be eating a little better
- Bugscope Team we ffind claws of some sort on almost all 'bugs'
- Guest we allredy did this in our school
- Bugscope Team this wasp came from Mahomet
- Bugscope Team from Ana
- Bugscope Team we were able to put one of your samples on the stub today, very quickly, and this was it
- Bugscope Team the potter wasp
- Bugscope Team it is a pretty nice looking insect
- Teacher thank;l,;
- Guest yes
- Teacher 'thanks
- 2:18pm
- Teacher we will see you later
- Bugscope Team you can see one of its forearms, which are called tarsi
- Teacher bye
- Bugscope Team Bye!
- Bugscope Team ok see you soon
- Teacher my next class will be in here in a few minutes
- Teacher We will get started around 2::25.....thanks!
- Bugscope Team Cool.
- Guest We are enjoying look at your insects. I gave my class a preview of our upcoming session on Tuesday.
- Bugscope Team great, Mrs Phelps
- Bugscope Team oh cool, im sure you are all excited
- Bugscope Team thank you for logging in
- Bugscope Team we really like doing this
- Bugscope Team it is always a little different
- Bugscope Team will your students be driving?
- Bugscope Team (the 'scope?)
- Guest Yes, I'll let them drive.
- Bugscope Team yay!
- Guest what are we looking at now?
- Bugscope Team thisis the wasp claw
- Bugscope Team the flat part, whoops, was the pulvillus
- Guest yuk
- Guest the kids are grossed out
- Bugscope Team Cate is resetting a couple of the presets that had moved slightly since she set them up earlier
- 2:23pm
- Bugscope Team this is a spiracle
- Bugscope Team like a nose
- Bugscope Team to a bug
- Bugscope Team for breathing, though, not smelling
- Guest what grade levels are at your school?
- Bugscope Team Mrs Clark's school?
- Bugscope Team we are doing a session with a high school in mahomet, illinois
- Bugscope Team 9th 10th 11th grade
- Bugscope Team Mrs Clark will be back on shortly, but this is good since we get to talk to you
- Teacher hi where here
- 2:28pm
- Bugscope Team yay!
- Bugscope Team welcome back!
- Teacher thank you
- Guest awesome!
- Bugscope Team this is a mystery bug with a big forehead
- Bugscope Team this is a closeup of the jaw
- Bugscope Team it is pretty smooth here
- Bugscope Team many ibsects are much '
- Bugscope Team d'oh
- Bugscope Team that one gort away
- Bugscope Team many insects are much hairier than this
- Bugscope Team below we see the edge of a palp
- Teacher what is a palp
Bugscope Team the insect uses them to manipulate its food or to taste/smell food
- Guest thanks for letting us join in
- Teacher sure
- Guest we'll see you next week
- Teacher enytime
- Teacher anytime
- 2:34pm
- Bugscope Team you can try focusing if you want
- Student what school is mrs phelps from?
- Student where are the presets?
- Bugscope Team Mrs C can you try F5?
- Bugscope Team We just gave you, as Clark1, control
- Bugscope Team nice imaging
- Student what is that in the eye?
- Student can we be published?
- Bugscope Team you mean in the paper?
- Bugscope Team sure!
- Bugscope Team mrs phelps was form a school in ulysses, ks
- Student the news gazette would be nice
- Student haha
- 2:39pm
- Bugscope Team we need to get back on the map with the News Gazette
- Student why is there a hair growing out of the eye?
- Bugscope Team this is high mag work!
- Bugscope Team sometimes the insect needs to be able to feel things that might be touching its eye
- Student do humans have hairs in there eyes?
- Bugscope Team and sometimes, like with fruit flies, it is helpful to be able to gauge windspeed
- Student our eyes*
- Bugscope Team no but humans do have nerves and can feel when something is touching their eyes
- Bugscope Team you would think so since there is the whole "hairy eyeball" thing
- Bugscope Team insects do not have nerves on the surface of their bodies because that surface is chitin -- the exoskeleton
- Student whats that? the hairy eyeball thing?
- Bugscope Team so they have to have, instead, setae that project through the cuticle, sense the environment, and report back to the nerves beneath
- Bugscope Team sometimes people will give you the hairy eyeball or to someone else
- Bugscope Team you have done something they did not like
- 2:44pm
- Bugscope Team Hi all!
- Student is that like a sucction cup?
- Bugscope Team yay annie is here
- Bugscope Team this is a really nice view of the potter wasp claw
- Bugscope Team it has lots of tiny setae on it that help it adhere to vertical surfaces
- Bugscope Team the tiny setae are called 'tenent' setae
- Bugscope Team Spiracle
- Bugscope Team Annie is here and may be able to help us with the mystery bugs
- Bugscope Team An insect nostril!
- Bugscope Team it is similar to a person's nose
- Student where is the spiracle located? and is it used for breathing
Bugscope Team can you see the 2 small holes along the side? those are each a spiracle
- Bugscope Team and yes it is used for breaking, or as a pathway for air to get inside the body
- Student what is the mystery bug
- Bugscope Team breathing
- Bugscope Team Annie is working on it
- Bugscope Team This is a termite!
- Student why is there no color
- 2:49pm
- Bugscope Team we are using electrons to collect these images
- Student what is this
- Bugscope Team this is the part of the mosquito that pokes you
- Bugscope Team the electrons from the microscope knock electrons out of the surface of the sample -- or the conductive coating on the surface of the sample
- Student the sucking part like a straw?
Bugscope Team yes exactly
- Bugscope Team and those 'secondary electrons' are collected as a signal that gives us the image we see
- Bugscope Team the electrons are collected as a signal and there is no color to the signal
- Student how can it pierce are skin
- Bugscope Team just gray scale imaging
- Student our*
- Bugscope Team you can see those serrated edges to the stylet
- Bugscope Team that is how it pierces your skin -- it is very sharp and can cut into your skin
- Bugscope Team owlfly larva
- Bugscope Team It is thin and the tip is sharp, just like a tiny needle. The mosquito injects a chemical into your skin that keeps your blood from coagulating. It is this chemical that makes mosquito bites itch
- Bugscope Team you can see that this guy's jaws are set up like a trap
- Bugscope Team like heparin
- Student what are those on the back of the bug
- Bugscope Team it has lots of tiny hairs
- Student awsome
- 2:55pm
- Bugscope Team in real life, when it is alive, the body would not be so small and sort of shriveled
- Bugscope Team this is the underside of the head
- Bugscope Team and this is the middle portion of the jaw
- Bugscope Team looks like a desert
- Bugscope Team with lots of little cacti on it
- Bugscope Team Cya guys!
- Student Thank you!!!! See you next year.!! we learned alot
- Bugscope Team Thank You!
- Bugscope Team See you next year!
- Student we thought the same thing about the cacti!
- Bugscope Team thank you for all your questions and your cool insects
- Bugscope Team Thank you all!!!
- Bugscope Team your member page has your chat and the saved images form today's sesion http://bugscope.beckman.uiuc.edu/members/2008-082/
