- Bugscope Team sample is pumping down...
- Bugscope Team still waiting for vacuum
- Bugscope Team which is creeping down
- Bugscope Team looks like it will be ready in 10-15 minutes, and I'll be racing to make presets
- Bugscope Team hello! welcome back to Bugscope!
- Teacher HI all - we are still getting ready here - probably 20 minutes until we are ready to interact :)
- Teacher So much fun!!
- Bugscope Team totally cool
- Teacher Great images!!
- Bugscope Team Gracias
- Bugscope Team hello Casey!
- Guest Hi there:)
- Bugscope Team we're finishing setup for today's Bugscope session with California State University -- East Bay.
- Bugscope Team brb
- Teacher Hi there - we are ready!
- Bugscope Team okay I think we are ready to roll
- Bugscope Team good timing
- Bugscope Team this is the odd little fly's left haltere, beneath a wing
- Bugscope Team this is one set of mechanoreceptors that keep track of the position of the haltere
- Guest crazy!
Bugscope Team ha Yeah!
- Teacher Tell us what a haltere is oh wise one.
- Teacher Who is casandra?
- Bugscope Team SEM is driving the 'scope now.
- Guest sorry I logged in twice im casey
Bugscope Team no problem
- Teacher Haltere?
- Bugscope Team halteres are modified hindwings (evolution!) that beat opposite the way the two wings in a fly (Diptera -- two wings) beat.
- Bugscope Team they function to balance the fly as it flies, kind of like gyroscopes
- Bugscope Team bees and wasps, for example, have four wings, as do dragonflies
- Bugscope Team bees and wasps both clip their fore- and hindwings together when they fly, so they fly with essentially two wings
- Bugscope Team but having four wings is not a huge problem for dragonflies, which can maneuver very quickly to prey on other flying insects
- Bugscope Team ha! it's a disembodied scorpion sting
- Teacher Is there a venom pore?
- Bugscope Team if you take the mag up on the venom pore (yes!) you can see crystals of dried venom
- Teacher Sweet!
- Guest I wanna see
- Bugscope Team this was in the sample yesterday, and I put it on this stub as well
- Bugscope Team now you can see the pore a bit better...
- Bugscope Team CSUEB is driving
- Bugscope Team pretty rad
- Bugscope Team flat little crystals
- Teacher focus?
- Teacher Who is driving?
- Teacher Are there bacteria on this view?
- Bugscope Team SEM was driving, and also correcting the astigmatism we were seeing
- Bugscope Team better now
- Guest what are the other things that aren't shaped like crystals?
Bugscope Team there are other dried liquid components; just seeing the crystals was a surprise
- Teacher hey marley here from csueb
- Bugscope Team scorpion venom has a lot of components init
- Teacher and brian and elspeth
Bugscope Team hello!
- Teacher we are fascinated by mites
Bugscope Team well you hit the jackpot here
- Bugscope Team they're living in a colony on the 'shoulder' of the earwig, where he cannot scrape them off
- Teacher how are they attaching to the earwig??!?!?!?!?!
- Bugscope Team they needa be able to move around a bit
- Teacher past tense: WERE they eating him?
- Teacher are they eating him?
Bugscope Team I am not sure if they eat debris that lands on him or -- if they feed on hemolymph
- Teacher WHAT is hemolymph?
- Bugscope Team hemolymph is insect 'blood'
- Teacher just in time for Halloween
- Teacher they look like crabs
Bugscope Team I think they are arachnids, like spiders, but I am not sure. I want to buy the definitive book on them but it is expensive
- Bugscope Team the spoonlike thing at the top is one of the tips of one of the limbvs
- Bugscope Team limbs
- Teacher Ah, I understand. We too are on student budgets.
Bugscope Team it's like $170
- Teacher how many limbs do they have?
Bugscope Team not sure maybe 6 or 8
- Teacher this is Brian now
- Bugscope Team you can see the head, barely
- Teacher say WHHAAAAAT?!?!?!? $170 dollars for a book on mites?
Bugscope Team exactically
- Teacher Marley is embarrased for me
Bugscope Team heh
- Teacher what are those little spines on its legs?
Bugscope Team they're sensory spines that help it feel what it is touching or what is touching it
- Bugscope Team the head is between those two big legs we see in the foreground
- Teacher follow up question: about how many mites are in this particular colony? If you had to guess
Bugscope Team there are 15 or so on this part of the body
- Guest ewww!
- Bugscope Team this is the head
- Teacher OMG XOXOSKELETON
- Teacher Are these the same mites that are on us on a microscopic level?
Bugscope Team no
- Teacher thank goodness
- Bugscope Team no eyes on these guys
- Teacher it's easier to see the whole mite when we are zoomed out
- Bugscope Team these are one of my favorite things to look at
- Teacher HOW DO MITES REPRODUCE?!
Bugscope Team this is a copout: I need to buy the book to find out, I'm afraid
- Bugscope Team I imagine they do it the same way many other critters do
- Teacher Ok we're signing off!
- Teacher oh just kidding!!!
- Teacher OOPS!
- Bugscope Team what?
- Teacher We have a new group coming up!!!!
- Teacher sorry
- Guest haha
- Guest this was really neato! but gotta head to class planning on checking in tomorrow thanks!
- Teacher is that the fungus?
Bugscope Team there is fungus in here -- yeah it is rotting
- Teacher This is Jennifer Tim and Martha
Bugscope Team hello!
- Bugscope Team moths, and also butterflies, can extend their probosces when they want to feed
- Bugscope Team they're like those New Year's party favor things
- Bugscope Team this is a portion of the antenna
- Bugscope Team this is a female antenna, much less ornate than that of a male
- Bugscope Team the antennae are covered with chemoreceptors
- Bugscope Team this looks like an empty socket
- Teacher Very interesting
- Bugscope Team Jes! The school is driving the 'scope. $600,000 microscope.
- Teacher Hello this is a new group-The SPIDER group
Bugscope Team um what would you like to see?
Bugscope Team maybe a fly?
- Teacher Can you take us to the Black Widow picture please
Bugscope Team you are driving.
Bugscope Team but let me know if for some reason it is not working
- Teacher We are having troubles getting to the Black Widow picture
Bugscope Team ok
- Teacher WHOA
- Bugscope Team the black widow is covered with mold
- Teacher WHat part is the eye?
- Teacher is that one eye ?
- Bugscope Team the two things in the background, bulbous
- Bugscope Team Captain Beefheart would say Fast and Bulbous, or actually he did say that.
- Bugscope Team now you can see the chelicerae, but they are covered with mold
- Bugscope Team the chelicerae, or chelicers, are what drive the fangs into the spider's prey
- Bugscope Team let
- Bugscope Team d'og
- Teacher ok you drive
- Bugscope Team heh let's look at the other spider
Bugscope Team since I'm driving
- Bugscope Team this is a boy spider
- Bugscope Team see where we are now?
- Bugscope Team you can see the crossed fangs in the center, and a drop of venom
- Teacher wow
- Teacher how can you differentiate the gender?
Bugscope Team males have larger palps, and I already looked there to see
- Bugscope Team see the cool plumose setae?
- Bugscope Team drop of venom
- Bugscope Team and a little better focus...
- Teacher how dangerous
- Bugscope Team you can see that the fang has tiny pores in it
- Bugscope Team this is something I have never seen before
- Bugscope Team sweet
- Teacher nice
- Bugscope Team tiny scratches on it from piercing insects
- Teacher what are the big dots?
- Teacher are those pores too?
Bugscope Team I don't think so.
- Teacher battle scars
- Bugscope Team there is likely some mineral component to the fangs, like calcium or zinc
- Teacher A new group is coming up
- Teacher thank you for the info
Bugscope Team sure!
- Bugscope Team uh oh
- Teacher wea
- Teacher we are the bee group
Bugscope Team there is a yellowjacket on the stub
- Teacher can you take us there please
- Teacher we are having trouble getting to the yellow jacket slide
Bugscope Team it'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
- Teacher oh, ok
- Bugscope Team this is the yellowjacket; you can see its eye, covered with graffiti
- Teacher graffiti?
- Bugscope Team someone else got here first and tagged the yellowjacket's right eye
- Teacher tagged?
- Teacher with what?
- Teacher a bug? a human?
- Bugscope Team now that we get up close, it looks like there were no taggers here; those are scales from another insect
- Bugscope Team I thought we might've nailed them...
- Bugscope Team like, maybe Shepherd Fairey was here.
- Bugscope Team there can be as many as 17,000 ommatidia in one large compound eye
- Bugscope Team you are doing a good job driving
- Bugscope Team the yucky things are moth or butterfly scales
- Teacher ommatidia?
- Bugscope Team the hexagons are the ommatidia, yes!
- Bugscope Team ommatidia are the facets of the compound eye
- Teacher do you think they got there from shipping? or in nature/life?
Bugscope Team yeah prob'ly from the insects all being in the same container
- Teacher thank you for your time
Bugscope Team Thank You!
- Teacher a new group is here
Bugscope Team Hello!
- Bugscope Team this is really beautiful
- Bugscope Team a chain of bacilli on an insect scale
- Teacher hi new group
- Bugscope Team see the rod shapes?
- Bugscope Team the rod shaped bacteria in a chain?
- Teacher What insect is the scale on?
Bugscope Team I'm sorry we can take the mag down to find out
- Bugscope Team this is pretty amazing considering they were not fixed in any way
- Bugscope Team this is what E coli look like, and anthrax, etc.
- Bugscope Team now we are pushing the capability of imaging at this working distance
- Bugscope Team if we were doing research on these we would change a few settings we cannot change now
- Bugscope Team if you now take the mag down you can perhaps see where we are
- Bugscope Team actually I think this scale is stuck to a rotting click beetle
- Guest Or how beautiful anthrax is.
- Bugscope Team scales are the fine powder you feel when you rub a butterfly's wings
- Teacher This 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 Team Hey Thanks, Michele.
- Teacher Signing off - THANK YOU FROM ALL OF us - seriously!!
- Bugscope Team Thank You!
- Bugscope Team Hey Kid are you still there?
- Bugscope Team Jes!
- Bugscope Team is anyone still paying attention?
- Bugscope Team ...
- Bugscope Team Thank you for signing on this evening!
- Bugscope Team Over and out!
