- Bugscope Teamsample is pumping down...
- 6:13 pm
- Bugscope Teamstill waiting for vacuum
- Bugscope Teamwhich is creeping down
- 6:19 pm
- Bugscope Teamlooks like it will be ready in 10-15 minutes, and I'll be racing to make presets
- 6:27 pm
- 6:34 pm
- 6:41 pm
- Bugscope Teamhello! welcome back to Bugscope!
- TeacherHI all - we are still getting ready here - probably 20 minutes until we are ready to interact :)
- TeacherSo much fun!!
- Bugscope Teamtotally cool
- TeacherGreat images!!
- Bugscope TeamGracias
- 6:47 pm
- Bugscope Teamhello Casey!
- GuestHi there:)
- Bugscope Teamwe're finishing setup for today's Bugscope session with California State University -- East Bay.
- 6:53 pm
- Bugscope Teambrb
- 6:59 pm
- TeacherHi there - we are ready!
- Bugscope Teamokay I think we are ready to roll
- Bugscope Teamgood timing
- Bugscope Teamthis is the odd little fly's left haltere, beneath a wing
- 7:05 pm
- Bugscope Teamthis is one set of mechanoreceptors that keep track of the position of the haltere
Bugscope Teamha Yeah!
- TeacherTell us what a haltere is oh wise one.
- TeacherWho is casandra?
- Bugscope TeamSEM is driving the 'scope now.
- Guestsorry I logged in twice im casey
Bugscope Teamno problem
- Bugscope Teamhalteres are modified hindwings (evolution!) that beat opposite the way the two wings in a fly (Diptera -- two wings) beat.
- Bugscope Teamthey function to balance the fly as it flies, kind of like gyroscopes
- Bugscope Teambees and wasps, for example, have four wings, as do dragonflies
- Bugscope Teambees and wasps both clip their fore- and hindwings together when they fly, so they fly with essentially two wings
- Bugscope Teambut having four wings is not a huge problem for dragonflies, which can maneuver very quickly to prey on other flying insects
- 7:11 pm
- Bugscope Teamha! it's a disembodied scorpion sting
- TeacherIs there a venom pore?
- Bugscope Teamif you take the mag up on the venom pore (yes!) you can see crystals of dried venom
- GuestI wanna see
- Bugscope Teamthis was in the sample yesterday, and I put it on this stub as well
- Bugscope Teamnow you can see the pore a bit better...
- Bugscope TeamCSUEB is driving
- Bugscope Teampretty rad
- Bugscope Teamflat little crystals
- TeacherWho is driving?
- 7:16 pm
- TeacherAre there bacteria on this view?
- Bugscope TeamSEM was driving, and also correcting the astigmatism we were seeing
- Bugscope Teambetter now
- Guestwhat are the other things that aren't shaped like crystals?
Bugscope Teamthere are other dried liquid components; just seeing the crystals was a surprise
- Teacherhey marley here from csueb
- Bugscope Teamscorpion venom has a lot of components init
- Teacherand brian and elspeth
- Teacherwe are fascinated by mites
Bugscope Teamwell you hit the jackpot here
- Bugscope Teamthey're living in a colony on the 'shoulder' of the earwig, where he cannot scrape them off
- Teacherhow are they attaching to the earwig??!?!?!?!?!
- Bugscope Teamthey needa be able to move around a bit
- Teacherpast tense: WERE they eating him?
- Teacherare they eating him?
Bugscope TeamI am not sure if they eat debris that lands on him or -- if they feed on hemolymph
- TeacherWHAT is hemolymph?
- Bugscope Teamhemolymph is insect 'blood'
- Teacherjust in time for Halloween
- Teacherthey look like crabs
Bugscope TeamI think they are arachnids, like spiders, but I am not sure. I want to buy the definitive book on them but it is expensive
- 7:21 pm
- Bugscope Teamthe spoonlike thing at the top is one of the tips of one of the limbvs
- Bugscope Teamlimbs
- TeacherAh, I understand. We too are on student budgets.
Bugscope Teamit's like $170
- Teacherhow many limbs do they have?
Bugscope Teamnot sure maybe 6 or 8
- Teacherthis is Brian now
- Bugscope Teamyou can see the head, barely
- Teachersay WHHAAAAAT?!?!?!? $170 dollars for a book on mites?
- TeacherMarley is embarrased for me
- Teacherwhat are those little spines on its legs?
Bugscope Teamthey're sensory spines that help it feel what it is touching or what is touching it
- Bugscope Teamthe head is between those two big legs we see in the foreground
- Teacherfollow up question: about how many mites are in this particular colony? If you had to guess
Bugscope Teamthere are 15 or so on this part of the body
- Bugscope Teamthis is the head
- TeacherOMG XOXOSKELETON
- TeacherAre these the same mites that are on us on a microscopic level?
- Teacherthank goodness
- Bugscope Teamno eyes on these guys
- 7:26 pm
- Teacherit's easier to see the whole mite when we are zoomed out
- Bugscope Teamthese are one of my favorite things to look at
- TeacherHOW DO MITES REPRODUCE?!
Bugscope Teamthis is a copout: I need to buy the book to find out, I'm afraid
- Bugscope TeamI imagine they do it the same way many other critters do
- TeacherOk we're signing off!
- Teacheroh just kidding!!!
- Bugscope Teamwhat?
- TeacherWe have a new group coming up!!!!
- Guestthis was really neato! but gotta head to class planning on checking in tomorrow thanks!
- Teacheris that the fungus?
Bugscope Teamthere is fungus in here -- yeah it is rotting
- 7:32 pm
- TeacherThis is Jennifer Tim and Martha
- Bugscope Teammoths, and also butterflies, can extend their probosces when they want to feed
- Bugscope Teamthey're like those New Year's party favor things
- Bugscope Teamthis is a portion of the antenna
- Bugscope Teamthis is a female antenna, much less ornate than that of a male
- Bugscope Teamthe antennae are covered with chemoreceptors
- Bugscope Teamthis looks like an empty socket
- TeacherVery interesting
- Bugscope TeamJes! The school is driving the 'scope. $600,000 microscope.
- TeacherHello this is a new group-The SPIDER group
Bugscope Teamum what would you like to see?
Bugscope Teammaybe a fly?
- 7:37 pm
- TeacherCan you take us to the Black Widow picture please
Bugscope Teamyou are driving.
Bugscope Teambut let me know if for some reason it is not working
- TeacherWe are having troubles getting to the Black Widow picture
- Bugscope Teamthe black widow is covered with mold
- TeacherWHat part is the eye?
- Teacheris that one eye ?
- Bugscope Teamthe two things in the background, bulbous
- Bugscope TeamCaptain Beefheart would say Fast and Bulbous, or actually he did say that.
- Bugscope Teamnow you can see the chelicerae, but they are covered with mold
- Bugscope Teamthe chelicerae, or chelicers, are what drive the fangs into the spider's prey
- Bugscope Teamlet
- Bugscope Teamd'og
- Teacherok you drive
- Bugscope Teamheh let's look at the other spider
Bugscope Teamsince I'm driving
- Bugscope Teamthis is a boy spider
- Bugscope Teamsee where we are now?
- Bugscope Teamyou can see the crossed fangs in the center, and a drop of venom
- Teacherhow can you differentiate the gender?
Bugscope Teammales have larger palps, and I already looked there to see
- Bugscope Teamsee the cool plumose setae?
- Bugscope Teamdrop of venom
- Bugscope Teamand a little better focus...
- Teacherhow dangerous
- 7:42 pm
- Bugscope Teamyou can see that the fang has tiny pores in it
- Bugscope Teamthis is something I have never seen before
- Bugscope Teamsweet
- Bugscope Teamtiny scratches on it from piercing insects
- Teacherwhat are the big dots?
- Teacherare those pores too?
Bugscope TeamI don't think so.
- Teacherbattle scars
- Bugscope Teamthere is likely some mineral component to the fangs, like calcium or zinc
- TeacherA new group is coming up
- Teacherthank you for the info
- Bugscope Teamuh oh
- Teacherwe are the bee group
Bugscope Teamthere is a yellowjacket on the stub
- Teachercan you take us there please
- Teacherwe are having trouble getting to the yellow jacket slide
Bugscope Teamit's not a slide, just to let you know; you are really driving a scanning electron microscope, and the images you see, that you generate, are live
- 7:47 pm
- Teacheroh, ok
- Bugscope Teamthis is the yellowjacket; you can see its eye, covered with graffiti
- Bugscope Teamsomeone else got here first and tagged the yellowjacket's right eye
- Teacherwith what?
- Teachera bug? a human?
- Bugscope Teamnow that we get up close, it looks like there were no taggers here; those are scales from another insect
- Bugscope TeamI thought we might've nailed them...
- Bugscope Teamlike, maybe Shepherd Fairey was here.
- Bugscope Teamthere can be as many as 17,000 ommatidia in one large compound eye
- Bugscope Teamyou are doing a good job driving
- Bugscope Teamthe yucky things are moth or butterfly scales
- Bugscope Teamthe hexagons are the ommatidia, yes!
- Bugscope Teamommatidia are the facets of the compound eye
- Teacherdo you think they got there from shipping? or in nature/life?
Bugscope Teamyeah prob'ly from the insects all being in the same container
- Teacherthank you for your time
Bugscope TeamThank You!
- Teachera new group is here
- 7:52 pm
- Bugscope Teamthis is really beautiful
- Bugscope Teama chain of bacilli on an insect scale
- Teacherhi new group
- Bugscope Teamsee the rod shapes?
- Bugscope Teamthe rod shaped bacteria in a chain?
- TeacherWhat insect is the scale on?
Bugscope TeamI'm sorry we can take the mag down to find out
- Bugscope Teamthis is pretty amazing considering they were not fixed in any way
- Bugscope Teamthis is what E coli look like, and anthrax, etc.
- Bugscope Teamnow we are pushing the capability of imaging at this working distance
- Bugscope Teamif we were doing research on these we would change a few settings we cannot change now
- 7:58 pm
- Bugscope Teamif you now take the mag down you can perhaps see where we are
- Bugscope Teamactually I think this scale is stuck to a rotting click beetle
- GuestOr how beautiful anthrax is.
- Bugscope Teamscales are the fine powder you feel when you rub a butterfly's wings
- TeacherThis is M Korb again here. We LOVED this session. We are going to read from Amy Stewart's book in a bit - wish you could join us!
- Bugscope TeamHey Thanks, Michele.
- TeacherSigning off - THANK YOU FROM ALL OF us - seriously!!

- Bugscope TeamHey Kid are you still there?
- Bugscope TeamJes!
- 8:04 pm
- Bugscope Teamis anyone still paying attention?
- Bugscope Team...
- Bugscope TeamThank you for signing on this evening!
