• 8:37 am
• Bugscope TeamGood morning Kristen!
• Guestgood morning!
• Guestwhat are we looking at?
• Bugscope Teamthis is milkweed floss
• Bugscope Teamgood morning, Joe!
• TeacherGood morning!
• Bugscope TeamWelcome to Bugscope!
• TeacherWhat should we be doing
• Teacher10 oclock right?
• Bugscope TeamJoe you should see presets to the right of this chat box. You can click (single click) on one to move to that place on the stub.
• Bugscope Teamwe have you on our schedule from 9 to 10 our time.
• Teacheractually...I had a picture...now I have a red X in the top left
• Bugscope Teamyou can also control the microscope using the controls you see to the right of the image
• Teacherright....10 oclock....just logging in....is this okay?
• Bugscope Teamhit refresh (F5) if you do not see an image
• Teachergot it
• Bugscope Teamyeah if you do not want to drive now we can ask Kristen if she would like to try controlling
• Guestoh yea! how do I do it?
• 8:42 am
• Bugscope Teamthings should have just changed on your control interface -- you should see controls now
• Guestok
• Bugscope Teamwhen you click to do something, one click should do it
• Teachermy controls are gone!
• Bugscope Teamyou can, for example, select one of the presets
• Bugscope TeamJoe I gave control to Kristen for now
• Teacherokay
• Teachernow....how exactly does this work?
• Bugscope Teamonly one person can drive the 'scope at a time
• Bugscope Teamwhen you connect, Joe, you can have your students log in, as students, and they can ask us questions
• Bugscope Teamwe can confer control to anyone you wish or you can keep it
• Bugscope TeamKristen please try clicking on a preset, or change the mag, if you would like
• Bugscope Teamif you have trouble let me know
• Guesti have tried that and also have tried to click and then center but i keep getting this message that says Admins have locked the controls
• Bugscope Teamd'oh! sorry now try...
• Bugscope Teamyay!

• TeacherOkay...I have to log off for a second and log onto the differnet compter....we will be back in a minute!
• Bugscope Teamthis is a wild-looking fly claw
• TeacherScott....do you have any milkweed bugs? You mentioned that you may have a couple
• 8:47 am
• Bugscope Teamthis is all stuff Cate found for us. the samples we got from Joe were completely totally smooshed.

• Bugscope TeamWe didn't have any; at the end of the winter it's slim pickin's for us.
• Guestso when we send our bugs we need to make sure we package them well!
• Bugscope Teamon this stub we have the fly, a large assassin bug, some aphids, two owlfly larvae, milkweed, a mosquito...
• Bugscope TeamYeah it is good if they are in pill containers -- something like that.

• Bugscope Teamand folded gently into Kleenex
• Bugscope Teamthis is a cerambycid beetle
• TeacherI am logged in....the teacher will be with you in less than 10 minutes...students are getting ready!
• Bugscope Teama longhorned beetle, like the Emerald Ash Borer
• Bugscope TeamJoe do you have workstations for students or will there be only one computer? We can work any which way...

• 8:53 am
• Bugscope TeamKristen I am going to turn control back over to PropelEast, to Joe.
• Guestok! Thank you so much for letting us try it - we can't wait for our turn!!!!
• Bugscope TeamUnless he does not want to drive.
• Bugscope TeamKristen when will we be working with you?
• Guestjust signed up, haven't got the confirmation yet!
• Bugscope TeamCool it should be coming soon. Kendra will take care of it.

• 8:58 am
• Bugscope Teamthese are tiny chemosensory setae on a palp on the longhorned beetle's head

• Bugscope Teamnow we are back to a lowmag view of the head

• Bugscope Teamand now we are looking at the antenna
• Bugscope TeamI am driving, just for fun

• Bugscope Teamthis is some sort of sensory pit on the antenna
• Bugscope Teamwith deflated mold spores in it
• 9:04 am

• Bugscope TeamKristen I just saw your application come in.

• Guestgood!

• Teacherwe are here and ready to go
• Guestmy students are really enjoying these pictures - they are already asking so many question
• Bugscope TeamYou have control of the 'scope PropelEast.
• Teacherjoe are you somewhere in the buidling
• Bugscope TeamYou are driving a $600,000 scanning electron microscope.
• Bugscope TeamPropel let us know when you have questions.

• Bugscope TeamYou can select from among the presets on the right or drive, change mag, whatever you would like.
• TeacherWhat are we looking at now
• Bugscope Teamthis is part of the longhorned beetle antenna, and we also see milkweed floss

• Bugscope Teamthe background is silver paint and doublestick carbon tape.
• Teacherwhat is milkweed floss
• 9:09 am

• Bugscope TeamIt's the fluff that comes out of milkweed pods.

• Bugscope Teamit helps carry the tiny seeds through the air
• Teacherwhy are items covered in silver
• Bugscope Teamthe sivler paint is only in the background -- the things we are looking at are actually covered with a super thin coat of gold-palladium that you cannot see at low mag.
• Bugscope Teamsilver, sorry

• Bugscope Teambut -- the reason we use silver paint and gold-palladium and carbon tape is so that the electrons that hit the sample and give us the images we see can go to ground -- so they can follow an electrically conductive pathway to ground
• Bugscope Teamif we did not coat the samples with gold-palladium they would charge up with electrons
• Bugscope Teamplease be sure to click on one of the presets

• Bugscope Teamthis is the compound eye of a mosquito -- just a few facets of the eye
• Teacherwe cannot see anything
• Bugscope Teamhit refresh (F5)
• Bugscope Teamdoes that work?
• Teacherthank you
• 9:14 am
• Bugscope Teamthese are ommatidia
• Teacherdo you like bugs
• Bugscope Teamif you take the mag down you can see where you are

• Bugscope Teamwe like bugs -- they are really interesting, diverse, quite different life forms

• Bugscope Teamnow you can see both eyes, and the base of the mouthparts, and some of the limbs
• Bugscope Teamthe mosquito is on its back -- its dorsal side
• Bugscope Teamit is mounted with its ventral side up
• Bugscope Teamyou can take the mag down further if you wish

• Bugscope Teamnow you can also see the antennae

• Bugscope Teamand now the wings!
• Teacherwhat is the blood sucking part of the mosquito called
• Bugscope Teamyou can see at the lower left, a micron bar that lets you now how large the field is
• Bugscope Teamit is called a fascicle
• Bugscope Teamonly the females bite
• Teacherthank you
• Bugscope Teamyou can see the fascicle at the top right
• Bugscope Teamit has a scale sitting on it
• Teacheris this a female
• Bugscope Teamthe fascicle is covered with scales
• Bugscope Teamyes this is a female
• Bugscope Teamthe males have, often, very ornate antennae
• Teacherwhy is it covered in scales
• Bugscope Teamscales are like tiny feathers
• Bugscope Teamthey can provide lift, for flying, and they can help insects that have them get out of spider webs
• 9:19 am
• Bugscope Teamscales are what make butterflies and moths feel so smooth
• Bugscope Teamthey look to us like powder

• Teacherwe are going to now look at salt from wendys

• Bugscope Teamthis salt apparently has an anticaking agent added to it that gives it that cool intricate geometric shape
• Bugscope Teamnormal salt just looks like cubes

• Teacherwe are now going to look at the caterpillar prolet
• Bugscope Teamthis is cool too

• Bugscope Teamthese are little claws called crochets
• Bugscope Teamon the proleg of the caterpillar
• Bugscope Teamthe caterpillar is softbodied
• Bugscope Teamyou can use click to center if you wish to look at another part of the caterpillar
• Bugscope Teamyou can see lots of tiny hairs called setae all over the body

• Bugscope Teamsetae help insects and other arthropods sense their environment
• Teacherwe learned about cabbage white this year
• Bugscope Teamit was a small white caterpillar and I am sorry I don't know what kind it is
• 9:24 am
• Bugscope Teamcool!

• Bugscope Teamnow you can see something else!
• Teacherwhat is in the lower right hand cover
• Bugscope Teamto the lower right
• Teacherconner
• Bugscope Teamyou can drive over to take a look

• Bugscope Teamif you use click to center you can center it on the screen
• Bugscope Teamgood job

• Bugscope Teamit is an aphid
• Teacherwe are getting better:)

• Bugscope Teamyes you are getting better
• Teacherdoes an aphid live on a captapillar

• Bugscope Teamthe tube on the right is a cornicle
• Bugscope Teamthey live on plants
• Teacherare they on a leaf together
• Bugscope Teamthat is a good point -- they could be on a leaf together
• Teacherscot what is your job?
• Teacherdo you like it
• Bugscope Teamants might protect the aphids from the caterpillar, but the caterpillar would not want to eat them
• Bugscope Teamyes I love what I do
• 9:30 am

• Bugscope TeamI am an electron microscopist.
• Bugscope Teamnow you have found the compound eye of the fly, which is likely a female.

• Bugscope Teamin flies, the males often have their eyes close together, and those of the females are further apart.
• Teacherwhy do they need compuond eyes

• Bugscope Teamit is helpful to have compound eyes if you want to have very good peripheral vision

• Bugscope Teamalso, having compound eyes makes it so that you can detect motion very quickly -- you get better updates
• Teacherwhat degree do you have
• Bugscope Teamsome insects can also see ultraviolet light using their compound eyes, but I am not sure it is compound eyes that lets them do that

• Bugscope TeamI have a degree in English and Biology and have been doing this for more than 25 years

• 9:35 am
• Bugscope TeamI started out doing transmission electron microscopy, looking at pigment cells in frogs and axolotls.
• Teacherhow did you learn to use an electron micro?
• Teacherwhat is axolotis
• Bugscope Teamtransmission electron microscopy (TEM) is how you see inside of cells

• Bugscope Teamaxolotls are neotenic salamanders

• Bugscope Teama neotene is a larva that acts like an adult
• Teacheris it true that when a fly lands on you, they throw up

• Bugscope Teamsometimes they throw up digestive juices to dissolve their food and then suck it up again

• Teacherwhat are we looking at now
• Bugscope Teamthis is the abdomen of the fly -- its belly
• Bugscope Teamyou can see the segments of the abdomen

• Bugscope Teamand the little black dots toward the center are spiracles, through which insects breathe
• Bugscope Teamthis is the head of an assassin bug
• Teacherwhat is this
• Teacherwhat is an assassin bug? where are they from
• Bugscope Teamit uses its proboscis to pierce its prey and suck the hemolymph out of it

• Bugscope Teamthey are found almost everywhere there are insects to eat

• 9:41 am
• Teacherwhat is on the left hand side

• Bugscope Teamthat is the hole the pin went through when someone had put this in a collection
• Teacheroutstanding
• Teacherthank you scot. we really enjoyed this!!!!! we do need to go now.
• Bugscope TeamThank You!
• Bugscope TeamYour images are stored as part of your database with bugscope.
• Bugscope Teamsession 2009-010 if you want to revisit them
• 9:48 am

• 9:59 am
• Bugscope TeamMark!
• Bugscope TeamI was hoping this guy would get on from Oklahoma
• 10:13 am
• Bugscope TeamNicky!
• Guesthello?
• Bugscope TeamHello!
• Bugscope TeamWhere are you from?
• Bugscope TeamDo you want to drive?
• Guestsorry
• Bugscope Teamhey where are you?

• Bugscope Teamha you are driving already
• Bugscope Teamthis is an aphid
• Bugscope Teamyou can choose from among a bunch of other insects/arthropods in the presets along the right side of the chat box

• Bugscope Teamthis is debris that comes, in part, from the critical point drying process
• Bugscope Teamoops

• Bugscope Teamthere you are

• 10:18 am

• Bugscope TeamI was watching the bottom of the chat window, not the top =(
• Bugscope Teamthat's ok mark, you'll get the hang of it, you can also admin talk using the tilda button

• 10:23 am
