- Bugscope Team getting ready to load sample
- Bugscope Team sample is in 'scope and pumping down
- Bugscope Team this is a CCD camera view of the inside of the chamber, just now
- Bugscope Team now we're making adjustments to the microscope
- Bugscope Team and soon, we'll be making the presets for today's session
- Bugscope Team welcome to Bugscope!
- Bugscope Team we just finished the presets
- Bugscope Team we are ready to roll
- Teacher Thanks! Students will be arriving in about 5 minutes and we are starting up laptops right now.
- Bugscope Team cool
- Bugscope Team let us know if you have any questions
- Bugscope Team you have control and are welcome to try driving as soon as you'd like
- Bugscope Team the presets are to the left -- you can click the left arrow there to see them. and if you click on one of them the 'scope will drive to that location on the stub
- Bugscope Team you can also change the mag, focus, contrast and brightness
- Bugscope Team and if you click on the screen, the 'scope will center the sample where you clicked
- Guest Hi everyone - great samples! Hello everyone in Alaska - from California :)

- Student so, do you know what specimen this is?
Bugscope Team this is the head of a male mosquito
- Student that is a cool picture
Bugscope Team awsomes I just gave you control of the 'scope
- Student this is the head of a male mosquitoe
- Student hey
- Student so does SEM stand for scanning electron microscope??
Bugscope Team yes that is right!
- Student What are facets?
Bugscope Team they are the individual components of the eye. Facets are also like the different sides to a diamond
- Student hello scot!
Bugscope Team hello!
- Student cool masqueto head

- Student y is it moving
- Student and what is that a picture of what bug??
Bugscope Team this is the head of a spider; you can see the eyes
- Student thats cool!
- Student i dont no
- Student how many insects have been discovered?
Bugscope Team hundreds of thousands, and there are still more
- Student how do u get a pic of a spider head?
- Student hey when was the microscope invented
Bugscope Team the electron microscope was invented in about 1931
- Student what is the stuff on the head
Bugscope Team there are bug hairs on it around this sphere/eye. Those are called setae (see-tee)
- Student what are the hairs coming off of it?
- Student what exactly do you do at your job?
- Student how big is the brain
- Student can i take control
- Student what type of bugs are we going to learn about?
- Student What Type of Spider is this
Bugscope Team sorry we are often not sure at all about spiders
- Student what is your favorite thing about science?
- Student why is there only spider heads?
- Student why do spiders have multiple eyes?
Bugscope Team the ocelli are good at seeing movement, but not at actually getting a very clear picture of things
- Student Who has the control over the microscope
Bugscope Team Jordy
- Student who has control? because this is really complicated!!!
Bugscope Team dude you can do it
- Student im super confused!!!!!!!!!!!!!!
- Student how many specinens
Bugscope Team there are 12 or 15 specimens today
- Student why does it look rinkly
- Student awsome
- Student what are all of your names?
- Student that is a really cool looking bug! :)
- Student how long does it take for the specinens to get damageed
Bugscope Team you mean by the electron beam? they will dry and fall apart before the beam hurts them badly
- Student y do the legs looks like a stike
- Student why do some spiders have lots of hairs & others dont have any?
- Student thanks for the reply
- Student how big is a spiders brain?
- Student Are the other 4 legs on the spider ripped off?
Bugscope Team Cate probably took a few legs off so she could get the spider to mount flat on the stub today
- Student going off bye
Bugscope Team Peace out
- Student who is evil oreos people
- Student why is it so blury?
Bugscope Team someone who is driving needs to focus
- Student approximately how many bugs do you look at under the scope in 1 day?
- Student bye
- Student noooooooooowwwww
- Student put ms.chin in charge please.
Bugscope Team Ms Chin is now the supreme ruler
- Student how do the eat?
Bugscope Team they inject their prey with venom that liquifies the prey's inside, then the spider drinks the insides like a milkshake
- Teacher I think we are going to have students shut their laptops so we can all focus on one screen and more questions
- Student bye scot and cate
Bugscope Team Bye! Thank You!
- Student what type of spider is that?
Bugscope Team we are not sure what kind it is, sorry
- Bugscope Team this is the butterfly claw
- Bugscope Team it is pretty interesting for a butterfly
- Bugscope Team you can see one of the two curved claw elements to the left
- Teacher Why do butterflies have claws?
Bugscope Team pretty much the same reason we have hands -- to grasp and hold things
- Guest Hi students in Alaska - this is a teacher in California (yes it is warm here today). I hear you are studying about characteristics of insects. What kinds of features do you see here today?
- Bugscope Team Michele I'm not sure the students are using their laptops anymore.
- Bugscope Team be sure and try some of the other presets. the more you go to, the more will show up in your database at the end of the session so you will have them to look at later
- Teacher Hi, they shut their laptops down but are anwering the quesions here. They would like to know what the hair like strand is near the claw
- Bugscope Team well this right here is a mite on the spider
- Bugscope Team those hairs are called setae, and they are often sensory -- they feel touch but also, sometimes they smell and sometimes they sense hot/cold
- Bugscope Team yeah I moved to that, sorry
- Bugscope Team 'cause I love mites
- Bugscope Team but I can put us back
- Teacher We just talked about mites living off of other artropods yesterday.
- Guest Hi Ms. Chin - I like their questions :)
- Bugscope Team some butterflies can smell with their feet, and the setae we see help them to that
- Bugscope Team the things streaming down like hair are actually hairs, bug hairs called setae
- Bugscope Team when a Monarch lands on a flower, it scrapes the surface with bristles on its feet, and the scent that arises from that scrape is sensed but some of the chemosensory setae that are also on the feet
- Bugscope Team often there is also a pad called a pulvillus or an arolium that helps the insect stick to a surface; claws are not always helpful when an insect wants to stick to something
- Teacher Why do ticks and mites live off of other arthropods?
Bugscope Team it's their niche, in a way
- Bugscope Team we find that mites are often on dirty insects, or insects that can't easily clean themselves. The mites might actually help clean them
- Bugscope Team insects and other similar arthropods are very opportunistic, and they find many ways of eating/surviving
- Bugscope Team we have found that some large centipedes may have hundreds of mites living on them
- Bugscope Team there are also many parasitic wasps that are tiny -- to us they look like flies
- Teacher How are ticks and mites related?
Bugscope Team they may both be arachnids
- Bugscope Team some mites may not be arachnids
- Bugscope Team this is a click beetle!
- Teacher We looked at some pictures of mites yesterday and it was difficult to tell how many body segments they have
Bugscope Team i think they are similar to ladybugs- they have a big shelled body and their head kind of pokes out with some legs
- Bugscope Team dustmites are softbodied, so they are hard to image
- Bugscope Team yes- did they get extra credit for doing that?
- Bugscope Team they are a good source of protein
- Teacher No extra credit!! Ha! We did read an article today about insects being high in iron and calcium and protein and low fat
- Bugscope Team click beetles, if you sit on them, will click their bodies, politely asking you to get off
- Guest Alaskan students are brave :)
- Bugscope Team pretty healthy, but it's usually the healthy stuff that doesn't taste good!
- Bugscope Team mmm
- Bugscope Team this is the head of some kinda aquatic insect larva
- Teacher If students open their laptops up again- how can we delegate control?
Bugscope Team you can ask us to have a certain student control and we can delegate the control to them
- Bugscope Team you can see the palps, which are like little limbs that help insects feed -- taste and manipulate their food into their mouths
- Bugscope Team caterpillars have six legs, because they are insects, and the things that look like extra legs are called 'prolegs.'
- Guest In my classes here, I had two to three students at a time come to the teacher computer to drive and ask questions. just a thought.
- Bugscope Team the prolegs often have lots of tiny hooks in them that help the caterpillars cling to surfaces
- Bugscope Team caterpillars may also produce web from spinnerets that are on the head
- Teacher Okay- we will have students com up and ask questions off of my computer.
- Guest Meanwhile, other students can take notes and come up with a list of questions in their notes :)
- Bugscope Team cool!
- Bugscope Team you can see the edge of the known world now
- Bugscope Team the specimens are all mounted on a 1.75-inch-diameter stub
- Bugscope Team the surface of the stub, which is aluminum, has doublestick carbon on it to hold the insects down
- Bugscope Team and there's also, often, silver paint to help attach them to the stub and also help make them conductive
- Teacher What are the petal-like things coming from the bottom?
Bugscope Team on the caterpillar/larva? those are folds of the exoskeleton where it shriveled after it died
- Bugscope Team the caterpillar is very scrunced up from being dried. It is very soft bodied.
- Bugscope Team we think this is an aquatic larva, like a stonefly or mayfly larva, that someone sent us. the heads and jaws are hardened shells (chitin, the exoskeleton), but the rest of the body is usually soft, as Cate says
- Teacher Under captivity, how long would a aqutic catterillar live?
Bugscope Team it depends on what kind it is; if you fed it well it would eventually metamorphose into its adult terrestrial form
- Bugscope Team some larva, once they become adults, have very short lives, some just a few hours
- Teacher what kind of bug is this?
Bugscope Team this is some type of true bug. we aren't sure what type
- Bugscope Team true bugs have piercing mouthparts they use on either plants for sap for bugs for bug blood
- Bugscope Team you can tell it is a true bug because it has those D'Oh Cate
- Bugscope Team I am so slow
- Guest :)
- Bugscope Team it looks like a Klingon
- Bugscope Team the central part of its head is a hydraulic pump that helps it suck liquids up from leaves, or limbs, or from other insects if it feeds on insects
- Bugscope Team or the queen from Aliens
- Bugscope Team a true bug can often be mistaken for a beetle
- Teacher what is the true bug like is it a beetle or if not what is it?
Bugscope Team they're not beetles although they resemble them, and they are not the Family Hemiptera, as I had said, but the Order Hemiptera, which includes cicadas, leafhoppers, stinkbugs, and aphids
- Bugscope Team yes cicadas are true bugs
- Bugscope Team assassin bugs and ambush bugs, which suck the juice out of other insects, are also Hemiptera
- Bugscope Team cicadas also have that kind of Klingon-looking central pump on their face
- Bugscope Team you can see the compound eyes on either side, and the antennae
- Bugscope Team I am going to have to slip out...
- Bugscope Team it was good to work with you today
- Bugscope Team bye from me!
- Teacher Thank you for all your help today Scot
- Guest Goodbye Scot
- Bugscope Team Thanks Scott, Chas, Cate! Thanks to Andrea and her bright students!
- Teacher We are wondering which part of the head has the hydrolic pump
Bugscope Team it's the ridged part between the eyes
- Bugscope Team this is a pinhole from the insect being mounted on a board
- Bugscope Team we thought the kids might like to see it
- Teacher They think that is pretty cool
- Guest That is amazing!
- Bugscope Team insects are a lot hairier than they seem!
- Bugscope Team here are some old looking pollen grains that are unfurling (at least the middle one is)
- Bugscope Team or the top one, I can't really tell
- Teacher Is this pollen found on a spider?
Bugscope Team yes it was found on the spider, but I'm not sure what kind the pollen grains are
- Teacher this is fifth period thank you for all the help and answers it was pretty cool
- Guest You all did a great job!
- Bugscope Team thanks for using bugscope with us today
- Bugscope Team We hope you all had a great time-- you all asked wonderful questions
- Bugscope Team you can go back to your chat and text at anytime from your member page-- https://bugscope.beckman.illinois.edu/members/2010-119
- Teacher This is Andrea- Thank you guys very much- we really enjoyed the session!
- Guest Talk to you soon! It was a pleasure to join you!
- Bugscope Team Thanks!
- Bugscope Team Andrea: You can elaborate on your experience in the evaluation form.
- Bugscope Team Bye Michele, Chas, and Cate!
- Guest Bye, Umesh!
- Guest Bye Bugscope team!
