- 5:02 pm
- Bugscope Teamventing the 'scope...
- Bugscope Teamsample is in and pumping down
- Bugscope Teamas soon as the vacuum is good enough, we'll make some adjustments and start finding presets
- 5:19 pm
- 5:24 pm
- Bugscope TeamHi Mikayla!
- Bugscope Teamwhere are you?
- Guestat haome
- Guestat home sorry
- Guestin Clermont, FL
- Bugscope TeamCool. We're setting up for a session at 6 our time, 7 your time. I'm making presets for that session.
- Bugscope Teamlet me know when you have questions.
- Guestawesome, thanks
- Bugscope Teamexcept about this because I am not sure what it is; it is kind of like an ant or wasp but it's not...
- 5:30 pm
- Bugscope Teamit has some serious mandibles
- Bugscope Teamand this is bacteria, on the eye
- Bugscope Teama lot of bacteria and some debris
- Bugscope Teamthis is a piece of a butterfly wing
- Guestthats really interesting
- Bugscope Teamthe scales are what feels like powder, seems like powder, when you rub a butterfly or moth wing
- 5:35 pm
- Bugscope Teamthey're responsible for color, both pigmented and structural (due to the width of the lattice, etc. they refract light in different colors)
- Bugscope Teamif your body was covered with scales like that and you flew into a spider web, there's a chance the scales would stick to the web but you could get away
- Bugscope Teamsilverfish have them too, and so do mosquitoes
- Guestwould that harm the butterfly
Bugscope Teamyes if the butterfly loses enough scales it cannot fly; they are also kind of like tiny feathers
- Bugscope Teamthis is a bunch of pollen from a lily
- 5:40 pm
- Bugscope Teamthis is the head of a cranefly, one of those flying insects that looks like a huge mosquito
- Bugscope Teamthe haltere, here has something on it, at the end, to the right
- 5:46 pm
- Bugscope Teamwhen the cranefly was alive the end of the haltere would have been more bulbous; it is now kind of dried out
- Bugscope Teamflies have two wings and two halteres that beat opposite the beat of the wings and provide stability in the air
- Guestthat is cool
- Bugscope Teamthis is a spiracle, which is what insects breathe through
- TeacherHello is anyone there yet
- Guestthis is all so interesting
- Bugscope TeamHey Jude
- Bugscope Teamthis is Scott, on three computers
- Bugscope Teamand Mikayla
- Bugscope TeamMikayla is in Clermont, FL
- 5:51 pm
- TeacherCool. We are global.
- Bugscope Teamalso, Joe is on. He's an entomologist here.
- TeacherI am here with 7 pre service teachers.
Bugscope Teamdo you have just one computer? can they log in?
- TeacherWe share this with two computers right?
Bugscope Teamyou can have as many as maybe 25 computers without causing too much lag
- Bugscope Teamwe can confer control to anyone who'd like it, one at a time
- Bugscope Teampresently you have control, Jude
- Bugscope Teambut I'm at the SEM and can drive directly
- TeacherSorry, I read the tutorial but don't recall how I give control over to others
Bugscope Teamyou just ask us. Joe can give you control, or I can.
- Bugscope Teamthis you can see did not work -- the fruitfly got covered with silver paint
- Bugscope Teamthese came out well, though
- StudentHi everyone what a cool site!
- Bugscope TeamHi Kirst!
- 5:56 pm
- Bugscope TeamHello.
- Studentwhat is the dark spot above the lower bug
Bugscope Teamthat is where the antennae are loose, and the area is charging up with electrons
- Studentooooo we like the eye...it looks fake!
- Studentgo closer on the eye
- Bugscope Teamwhen a sample is not well coated with gold-palladium, from the sputter coater, it can charge up with electrons when the electron beam passes over it
- Studentcan you put it on the other bug?
Bugscope Teamit's not gonna be so pretty...
- Bugscope Teamthose are the pedicels of the antennae
- Bugscope Teamthe bases, and they have an organ inside them that helps capture the vibrations from other flies
- Bugscope Teamthe branches parts of the antennae are called the aristate antennae
- Studentdo you have any of the insects we sent?
Bugscope TeamI am sorry --- I don't know. Cate made the sample earlier, and I am not sure if she used your samples
- 6:02 pm
- StudentIs the stuff that looks like hair really hair?
Bugscope Teamit's not really hair but it is convenient to call it hair. we call them 'setae' (see-tee)
- Studentwhat is the purpose of the little tiny hairs?
Bugscope Teamthe tiny hairs are mostly for mechanosensing. since insects have an exoskeleton, they use these hairs to sense changings in the environment about them, particularly small movements in the air, or something closeby touching them.
Bugscope Teamthese hairs are called setae, (pronounced: see-tee)
- Bugscope TeamJude is it alright to give someone else control?
- Bugscope Teamcompound eyes also give the insects an advantage because they are very sensitive to changes in the visual field, as Joe said...
- GuestI am a guest
- StudentMikayla, are you a student, teacher, or part of the team?
Bugscope Teamshe is one of our friends from FL
- TeacherYes, give others control
- Bugscope TeamKirst I just gave you control.
- Bugscope Teammaybe Joe can tell us what this is
- GuestIs that why it is almost impossible to swat a fly?
Bugscope Teamyea, that's one of the reasons. although it is possible once you learn that they tend to fly backwards a bit when they take off.
Bugscope Teamthey also have fairly good vision, that allows them to sense any sudden movements very well.
Bugscope Teamsry, fly backwards when you are coming from the front. (the direction they takeoff in depends on the angle you're coming in at)
- Studentwhat is this?
- Bugscope Teamwow
- Bugscope Teamant?
- Bugscope Teami'd have to see the antennae more
- Bugscope Teamhere we see where the mandible attaches to the head, and we see the compound eye
- Bugscope Teamit's not quite like an ant or wasp
- 6:07 pm
- Bugscope Teamthis is some kind of borer
- Bugscope Teamyou can see its many-jointed forearm -- all of the tarsi
- Bugscope Teamoooh is this a buprestid?
Bugscope TeamI think so, not sure.
- Studentare those teeth?
Bugscope Teamthey don't really have teeth, but sometimes the mandibles are hardened
- Studentwhat are those 2 small white thingys?
Bugscope Teamthose are palps, one pair of palps
Bugscope Teamthese are used for tasting (gustatory senses)
- Bugscope Teampalps are accessory mouthparts that help insects taste and also manipulate their food
- StudentWe all laughed!
- Studentdo you have lice or bed bugs?
Bugscope Teamnot today, not in this sample
- Bugscope Teamwe've had bedbugs in the 'scope in the past, and also lice
- Bugscope Teamthankfully none at home
- Studentcan you give Tim control? I'm computer shy...
Bugscope TeamTim is the Supreme Ruler
- 6:12 pm
- Studentcan you tell by looking at different kinds of insects that bore what they bore into? (does that ? make sense?)
Bugscope Teamyes, to a degree. the mouthparts often depend more on what order the particular insects belong to. but within an order, you can make pretty good guesses as to what their food/host may be.
- Studentwe're in trouble now!
- StudentKing of the ant hill!
Bugscope Teamdude it means you have a lot of responsibility
- StudentIn our class too!
- Bugscope Teamthis is a true bug, not sure what kind
- Bugscope Teamtrue bugs have piercing/sucking mouthparts
- Bugscope Teamassassin bugs and ambush bugs have three-segmented probosces that stick into other bugs
- StudentI thought so, sorry about my spelling
Bugscope Teamwe have more practice with those words, of course
- StudentSo Joe, what does this sample bore in to?
Bugscope Teamprobably wood. it's got pretty large/stout mandibles for a beetle
Bugscope Teamand if it is a jewel beetle, then wood for sure.
- StudentOops I phrased that wrong
- Studentis that a mosquito then?
Bugscope Teammosquitoes are not true bugs; I didn't tell you the whole definition. mosquitoes are flies (mosca = fly and -ito = small)
- StudentThat wasn't an accident Kirsten!
- StudentSorry Mikayla.
- StudentDo you have male or female genetaila that we can see?
Bugscope Teamwe can move to the tip of the abdomen of this or the buprestid
- 6:17 pm
- StudentSo is this a boy or girl?
Bugscope Teamnot sure about this
- Studentwhat are some of those differences?
- Bugscope Teamwhen you see an earwig, the ones with bowlegged cercopods (the pincers) are males
- Bugscope Teamfemale earwigs are more demure
- Bugscope Teamoften the genitalia are on the inside; often you cannot distinguish sexes, although we can tell you how to spot some differences
Bugscope Teamyea, this is definitely true, sometimes they get bloated and the genitalia comes out, but not always
- Bugscope Teamwith houseflies and some other flies, the eyes of the males are close together, kind of like Mikhail Baryshnikov.
- Bugscope TeamFemale fly eyes are often farther apart, like Uma Thurman.
- Bugscope Teamwith spiders there is often a big disparity in size, and the males have these kind of boxing glove pedipalps compared to the female pedipalps, which are smaller
- StudentYou have used these jokes before
Bugscope Teamsorry DaddyO
- Studentdo any have horse faces like Julia Roberts?
- 6:22 pm
- Bugscope Teamalso, with moths and mosquitoes, the antennae are more frilly in the males
- Studentare the pedipalps on the foot?
Bugscope Teamthey'e the palps on the head closest to the chelicerae, which hold the fangs
- Bugscope Teamthe boxing gloves in male spiders deliver sperm packets
- Bugscope Teamthis preset had moved a bit since we made it
- Bugscope Teamsee the bacilli?
- Teacherplease give control cuw class ....thanks
- Studentdo you have any samples that would show a chelicerae, pedipalp, etc?
Bugscope Teamlet me see if I can find the spider; I'd forgotten about it
- StudentI think is that what we see?
Bugscope Teamit's actually almost all bacteria, not frass
- Bugscope Teamcan I drive for a sec?
- Studentyes please!
- StudentJulie's drunk off jello shots so she shouldn't be driving anyway
- Bugscope Teamhaha sorry the spider is a disaster
- Bugscope Teamwow
- Bugscope Teamyou can't see anything on this except legs
- 6:28 pm
- Bugscope Teamwell CU Class you can have the controls back now
- StudentDo you use this same language with elementary students?
Bugscope Teamwe use the technical names for the features, yes
Bugscope Teambut this is also accompanied by definitions in simpler terms
- StudentHow many computers can view at once?
Bugscope Team25 to 30 before it starts to lag
- Bugscope Teamthe little indentations have setae in them, not sure why, but the indentations make the exoskeleton look shiny
- StudentHow long has this site been up?
Bugscope Team14 years; we are older than Facebook, older than Google I think
- StudentHow much does it cost on your end to put on a session like this? Supplies and Time?
Bugscope Teamyeah, time on the 'scope, sputtercoating, silver paint
- Bugscope Teamwhen we started out we had a more primitive user interface
- Studentwhat is the purpose of its ridges?
- Bugscope Teamurticating means 'itching'
- 6:33 pm
- StudentIrritant???...sounds like my husband
- StudentDo you work on the site as a volunteer?
Bugscope Teamyea, this is mostly volunteer/outreach for us
- Bugscope TeamI was hired to help start Bugscope at the end of 1998
- Bugscope Teamspiders, some spiders, have what are called urticating hairs that they can release when, for example, a dog is sniffing them
Bugscope Teammoths also have these, some of them are really bad
- Bugscope Teamour first official session was March 19, 1999
- Studentwhat is a spiracle?
Bugscope Teamthat is what insects breathe through; there are two on each segment, on either side, usually
- Studentwhats the best elementary question?
Bugscope Teamkids always want to know what the hairs do, what the claws are for, about the same as big people
- StudentWhat are some questions that usually arise when you do this with younger students?
Bugscope Teama lot of times they ask about the size of these things, and definitely function of different structures
- StudentIf scheduling a time with our students, how far in advance should we plan? How many sessions can we schedule in a day?
Bugscope Teamwe can schedule only two sessions per week because we share the 'scope with researchers. we also need an hour to set up, often a little less than that
- StudentYou guys are fun, would we always get you?
Bugscope TeamI am almost always on.
Bugscope Teami try to be here often, but i have trouble waking up early, so....
- 6:38 pm
- Bugscope Teamwe have connected with Australia, Ireland, Tanzania, Sri Lanka...
- Bugscope Teamwhen we connect with adults we are sometimes a little more radical, but we want the kids to have fun
- StudentIf we wanted to use this in a class how far in advance do you need to know?
Bugscope Teamit is good to plan at least a month in advance and sometimes more because we get busy
- Bugscope TeamThank you!
- StudentThanks a lot for the session! This is going to be a great tool to use with our future classes.
Bugscope Teamyou're welcome. this is pretty fun for us, and i think a really good resource for bringing technology otherwise no available to children
- Studenthow can we support you?
- StudentHow could we support you to maintain your site?
- StudentWhere do you get your funding?
- StudentChloe's mom always copies me...
- Bugscope Teamwe self fund; this is good publicity, at least we think it is, for the U of Illinois and for the Beckman Institute
- StudentSure newbie aka Kirst!
- StudentThank you. We had fun!!
- Bugscope Teamwe started with a grant from the NSF and several smaller grants from a variety of places, including the Lumpkin Foundation.
- TeacherThank you for the session tonight and having good humor about the over tired adults in this classroom :0
- StudentThis session might not be good publicity
Bugscope Teamhaha it'll be fine
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2012-133
- Bugscope Teamthanks! see you all in the future.
- TeacherWe really appreciate it. Please approve my next session....
Bugscope TeamI think Kendra will take care of it.
- TeacherThank you and good night.
- TeacherFor sure I have requested a session for another college course.
Bugscope TeamI think I saw it in email.
- 6:43 pm
- Bugscope TeamThank You, Everyone!
- Bugscope Teamover and out...
- TeacherCool. Michelle Korb has asked us to participate in her research project.
- Bugscope Teamnight!
