- 3:12 pm
- 3:18 pm
- Bugscope Teamhi gerri, welcome to bugscope!
- Teacherhi there!
- Teacheri am nervous about this...haven't done this before and i decide to do a demo. am i crazy?
- 3:23 pm
- Bugscope Teamwe just finished setting up presets
- Bugscope Teamno no no, it's not a problem.
- Bugscope Teamthings will go fine, please don't worry, we are here to help
- Bugscope Teamlet's talk a bit, and get you feeling better
- Teachersounds good
- Bugscope Teamso, first thing, you can control the scope via the controls on the right. if you really don't want to control, we can control for you
- Teacheri am actually connecting via live videoconferencing to schools across the state
- Bugscope Teamwow, cool
- Teacheri'll be talking to them live while they see my screen
- Teacheri would like them to be able to login as well. i can do that, correct? by sending them to the\live screen?
- Bugscope Teamare people going to be logging in as guests or students?
- Bugscope Teamoh, yes, totally, others can login
- Teacherwhat should they be? guests or students?
- Bugscope Teamif they are from your same network, they can login as students, if not, then they can login as guests
- Teacherok...they will be guests
- Bugscope Teamyep, anyone in the world can login as guest, no password, just visit /live
- Bugscope Teamyou got it
- Bugscope Teamnow, about how many are planning on logging in?
- Teacherwe officially start at 4:00, right?
- Bugscope Teamif we have more than 20-30, then it gets way too much chat
- Bugscope Teamyes, 4PM start time
- Bugscope TeamHello!
- Teacheri don't think we will have that many login
- Bugscope Teamso, if we can have 10-20 logins, the session will go perfect
- Teachersounds good
- Teacherhow do i drive this thing :)
- Bugscope Teamyou want to pratcice? yeah, just try it out
- Bugscope Teamclick on "click to center"
- Bugscope Teamwait, there ya go!
- Bugscope Teamokay, sorry bout that, that was scott moving the scope
- Bugscope Teamok, now give it a try
- Bugscope Teamclick on any of the mavicgation controls
- Bugscope Teamthe easiest is magnify, you can zoom in or out
- Bugscope Teamwhen using navigation, try click to center, that is much easier than click to drive
- 3:28 pm
- Teacherhow do i get back to a preset?
Bugscope Teamyou can click on any preset at any time and it'll take you there
- Bugscope Teamjust click on it
- Teachernevermind! see them now
- TeacherWhat are we looking at?
- Bugscope Teamthis is a fly, a smashed fly head
- Bugscope Teamoh wait, it's a mosquito, not a fly
- Bugscope Teamthe compound eye is the bumpy thing
- Teacheris it a smashed mosquito?
- Bugscope Teamthose bumps are the individual facets of the eye, called ommatidia
- Teacherthe crater looking things are on the eye?
Bugscope Teamyep, those are the facets, ommatidia, each one has a lens in it
- Bugscope Teamand as you can see, insects are very very harry. those hairs are called setae (pronounced see-tee), they help insects the feel their environment
- Bugscope TeamThe eye is caved in because the skeeter is dried out.
- Bugscope Teamnormally the eyes are bulbous.
- Teacherhow interesting!
- Bugscope Teamthis is a female mosquito -- the ones that bite
- Teacherwhat is the gauze looking thing?
- Teacherlooks like an upside down U
- Bugscope Teamum one of the palps, maybe?
- Bugscope Teamoh, that's the eye - the compound eye
- Bugscope Teamtake the mag and see!
- Bugscope Teamyeah, increase the mag, give it a try
- Bugscope Teammag up and see. that is
- Bugscope Teamsry meant to say that's the eye, but already answered
- Bugscope Teamhey man no problem
- 3:33 pm
- Bugscope Teamcheck it out now
- Teacherhow strange
- Bugscope Teamthe ommatidia look like little baby marshmallows
- Bugscope Teamwe moved the scope a bit for ya, now you can see those ommatidia, each one (ommatidium) has a lens in it
- Bugscope Teamand you can see one of the scales
- Bugscope Teamsome ommatidia look like hexagons too, although these are move like spheres
- Bugscope Teamtry zooming in on the scale near the top, scales are cool, way cool
- Bugscope Teamthe scales look like palm fronds and indicate that the mosquito is a martyr. it's a saint
- Bugscope Teamlike in religious paintings...
- Teacherdo i center it first?
Bugscope Teamgood idea, yeah
- Bugscope Teamsounds great!
- Bugscope Teamcenter it first, then zoom in
- Bugscope Teamthere you centered the scale
- Bugscope Teamyeah, there ya go, it's not too hard huh?
- Bugscope Teamgood job, Gerri
- Teacherno, it is good :)
- Teacherwhat part am i looking at now?
Bugscope Teamthe scale is centered
- Bugscope Teamif the focus is out of wack, try to change it, that can be hard though, go one way and if it gets worse go the other way
- Bugscope TeamGerri there are 25 presets on the stub, so far, so you can choose from among any of them, and you can drive around from wherever you are
- Bugscope Teamoh look it magically focussed!
- Teacherthis is really amazing
- Bugscope Teamthe scale gets really interesting when you get even closer
- Teacheri am getting ready to get the sites from around the state connected
- Teacherwill do an overview of Bugscope
Bugscope Teamokay cool, just let us know when you need us for anything
- Bugscope Teamgerri, also, make sure to keep in mind, we can give control of the scope to ANYONE who is logged in, a guest, a student, anyone who is logged in
- Bugscope TeamGerri try any of the presets, when you feel like it; you can scroll through them
- Teacherand then will be back right at 4:00
- Bugscope Teamcool we will be making a few more presets
- Teachercan i go ahead and log out and then just come back?
- Bugscope Teamsure, see you in a bit
- 3:38 pm
- Bugscope Teamchow
- Bugscope Teamsee ya
- 3:47 pm
- Bugscope Teami'm in larry hanks' lab
- Bugscope Teamworking on cerambycids
- Bugscope Teamgetting a project started on a genus endemic to the hawaiian islands
- Bugscope Teamjust started this past fall
- Bugscope Teamthat sounds like a good plan
- Bugscope Teammight have to do a few field trips
- Bugscope Teambut you won't need an electron microscope 'cause they should be really huge dudes, right?
- Bugscope Teamyea money is the problem writing some grant proposals now
- Bugscope Teamlike industrial sized cerambycids?
- Bugscope Teamthey're sort of medium sized
- Bugscope Teamare they nice colors?
- Bugscope Teaman sem would help to see if they have these gland pores that annie had found
- Bugscope Teamon cerambycids in the same tribe
- Bugscope TeamDude you're gonna be looking at prothoraces.
- Bugscope Teamyup
- Bugscope Teamprofessional thoraxes
- Bugscope Teamthey're actually kind of drab surprisingly
- 3:52 pm
- Bugscope Teamawww
- Bugscope Teammost of them do have a light coloured stripe to them
- Bugscope Teamand they look somewhat streamlines
- Bugscope Team*streamlined
- Bugscope Teamso racecars?
- Bugscope Teamcool
- Bugscope Teamare they found only in Hawaii?
- Bugscope Teamas far as i know
- Bugscope Teamthere's another grad student interested in joining in
- Bugscope Teamis there room or would that clog up the system
- Bugscope Teamnvm
- 3:57 pm
- Bugscope TeamSorry I hadda go help someone for a sec
- Bugscope Teamcertainly there is room
- Bugscope Teamah it's ok, she was actually just interested in joining at another time
- Bugscope Teami misunderstood
- Bugscope Teamhi gerri, welcome back to bugscope!
- Bugscope Teamhi Gerri!
- Bugscope TeamHi Ponder!
- Teacherhi guys
- Bugscope TeamHi small g gerri!
- Bugscope Teamhi
- Teacheri just gave an overview of who bugscope is
- GuestHello Gerri from New Caney ISD :)
- Teacherlet's give them a minute
- Bugscope Teamwelcome to bugscope everyone
- Bugscope TeamWelcome to Bugscope!
- Bugscope Teamawesome. let us know when you have questions. Gerri is driving now, and we can let other people drive, one at a time, as you wish
- Teachergiving them another 30 seconds or so
- Bugscope Teamon this end we can confer control to whomever we wish
- GuestI'm a guest now :)
- Bugscope Teamfor example if a teacher wants us to give a certain student control, we can
- Teacherscot...you can give control to students as well, correct?
Bugscope Teamyes we can, one at a time, but we ensure that it is alright with their teacher
- Bugscope TeamPonder we can give you control as a guest no problem
- Bugscope Teamthis is a fruit fly and it looks particularly good because it was not airdried
- 4:02 pm
- Bugscope Teamthis fruit fly was critical point dried from ethanol, which we can do when we have time
- Teacherscott...one of my participants was having problems....all is good now
- Teacheri can drive and move around, right
Bugscope Teamyep, you have control gerri
- Bugscope TeamGerri let us know if you want anyone else to drive. Yes you can!
- Teacherthis is a fruit fly?
- Bugscope Teamyep, a fruit fly's head
- Bugscope Teamyou can see the compound eye
- Teacheri want to look at his eyeball...so let's see if i can do that now
- Bugscope Teamit's mouth parts are pointing to the upper left
- Bugscope Teamalso, all those hair like things are not actually hairs, they are called setae (pronounced see-tee)
- Bugscope Teamand you can see the antennae and the palps, and the sponging mouthparts
- Bugscope Teamhi Becca!
- Bugscope Teamgive it a try, just zoom in
- Bugscope TeamBecca and Joe are entomology students who are helping us today
- Bugscope TeamHi everyone!
- Bugscope Teamgood driving gerri
- Bugscope Teamyou can see that the compound eye has lots of tiny bristles on it.
- Bugscope Teamzoom in every more, yeah, there ya go
- Teacheri am going to focus a little
- Bugscope Teamthose are mechanoreceptors, and they help the fruit fly gauge windspeed
- Bugscope Teamyou can tell that focus is either up or down, one way or the other
- Bugscope Teamnotice that even this compound eye has the setae (hairs ) on it. we think those setae air in the flying in that they sense wind direction and speed, so that helps the fly to make sudden changes in direction
- Bugscope Teamyou can kick the mag up if you want, as well
- Teacherhow do you know that they help the fly gauge windsepped?
Bugscope Teamgood question. i don't think anyone knows for certain. but, we do know about setae on other parts of the insect, setae have different functions, and many setae are mechanosensory in that they sense movement. these are mechanosensory, so they sense movement
- Teacheri think alex just answered me
- Bugscope Teamapparently people have determined that experimentally
- Teacheron the left, you are keeping track of our questions, right?
Bugscope Teamyes, when we specifically answer a question, it gets moved to the left side
- Bugscope Teamwhenever we grab a question and answer it that way it goes over there
- Teacherlet's zoom out and look at something else on this fly
- 4:07 pm
- Bugscope Teamsome setae are mechanosensory, some are chemosensory, and some are hot/cold sensors
- Bugscope Teamspiracle
- Teacherwhat is in the center now?
- Bugscope Teamthe sponging mouthparts
- Bugscope Teamand a couple of palps
- Bugscope Teamthere is some kind of juju on the mouth
- Bugscope Teamlike the fly spit up, sorry
- Teacherwhere is the juju?
- Bugscope Teamjuju is just our name for dirt, grime, stuff like that
- Teacherbut where is it in this picture?
- Teacheri see what looks like a clam with spikes
- Bugscope Teamif you zoom in near the hairs, that looks like dirt there, some of it maybe
- Bugscope Teamnormally this part of the mouth would actually look spongy, with pores in it, but there is a bunch of oily stuff at the base of the setae
- Teacheri am going to go to one of the presets
Bugscope Teamtotally cool
Bugscope Teamokay, sounds good
- Teacherin the bottom right
- Bugscope Teammosquito head!
- GuestI'll drive
Bugscope Teamokay, ruiz, you have control now
- Bugscope Teamthis is a female mosquito
- Bugscope TeamPonder you are the supreme ruler.
- 4:12 pm
- Bugscope Teamone thing to remember about driving: if you use click to drive, click once to drive and once to stop
- Bugscope Teamthese are scales
- Teacherscales on what?
Bugscope TeamI think that is the facsicle
- Teacheri know the mosquito, but where are they located on the mosquito?
- Bugscope Teammosquitoes, moths, butterflies, silverfish, and some weevils and few beetles have scales
- Bugscope Teamthe scales are all over the place, they look like think leaves maybe?
- Bugscope Teamthe tube that holds the biting apparatus
- Bugscope Teamright in the center of the image, those are scales
- Teacherkind of look like pantry moths stuck on a wall :)
- Bugscope TeamSo the hypothesis that those short hairs are used to detect wind speeds and current flow during flight comes from the fact that they are short and highly organized, and also singularly innervated.
- Guestwhat are the round things in the background
Bugscope Teamthose are bumps in hte tape that we stick the bugs to
Bugscope Teamon the upper left?
- Bugscope Teamif you didn't know this was a female you could also tell that it is female from the antennae
- Teacherhow do you know it is a female?
Bugscope Teambecause it has a non-frilly antenna, and because it has a fascicle that it uses to suck blood; males do not bite
Bugscope Teammales have a smaller mouth part, and the antennae will be feathery looking
- Bugscope Teamthis is a crater in the sticky tape
- 4:18 pm
- Bugscope Teamplease be sure, anyone, to ask us questions if you want
- Teachersorry...was talking to a site via videoconferencing
- Bugscope Teamthere is another skeeter in here as well
- Guestanyone else want to drive?
- Teacherwhere is the other skeeter?
Bugscope Teamit is to the north and west
- Bugscope TeamJoe what is the base of the antenna called? I always forget.
- Teacherwho wants to drive next?
- Bugscope Teamno the scape is part of the antenna; I mean the pad at the bottom
- GuestI'd love to drive
Bugscope Teamgot it
- Bugscope Teamjennden, you've got control of the scope now
- Bugscope Teamthis is a $600,000 electron microscope you all are controlling
- 4:23 pm
- Teacherwhat are we looking at now?
- GuestThis is too cool! Who wants to drive now! Love It
- Bugscope Teamthis is part of the mosquito
- Bugscope Teamthe base of the antenna, or maybe a palp, hard to tell
- Teacherlet's look at a different critter
- Bugscope Teamif you zoom out we could see it better
- Guestare there any bugs on the endangered species list?
Bugscope TeamThere are several endangered insects, for example, there is a beetle in Nebraska that is only found in a salt creek. I don't know if we have any to look at.
- GuestThank you for the drive
- TeacherI would like to try!
Bugscope TeamGuest you have control now.
- Teacheri'll drive again for a bit until someone else wants to
- Bugscope Teamlet us know anytime you have questions
- Bugscope Teamthe edge of the world
- 4:28 pm
- Bugscope Teamwe drove off the edge there, i fixed it, should be working again
- Bugscope Teamusing "click to center" is much easier than click to drive.
- Bugscope Teamyou can see two of the spiracles
- Bugscope Teamthe little black pores
- Teacherthey are pretty hairy, right?
Bugscope Teamyes they are!
Bugscope Teamwell, yeah, but not really hairs, those are called setae
- Bugscope Teamthe round thing is one of the halteres
- Teachergot it
- Bugscope Teamsetae stick through the exoskeleton, to nerves underneath. that's how the insect feels things
- Bugscope Teamthe haltere that scott is referring to is the thing between the second and third leg
- Teacherwhy is it important for scientists to be able to magnify these guys?
Bugscope Teamthey would like to be able to compare characteristics between and among species
Bugscope TeamThere are a lot of things going on with the insect structure that can be used to help technology along too, so we can get an idea of how to build spider silk, for example.
Bugscope Teamit's also useful in that some structures can't be seen unless they're under such high magnification, for example in my work, you can't really see the gland pores that are on the prothorax of the beetles with your naked. eye
- Bugscope TeamThere are even bigger hairs we call bristles that can be used for either sensing things or for defense.
- Bugscope Teamthere are many things that can be discovered by using an electron microscope. for example, brochosomes (tiny excretions from the leafhopper insect) were not even know to exist until someone put a leafhopper in an electron microscope in 1958.
- GuestWhat is the turn around time from when you receive the bugs that we send for us to be able to see them on the bugscope
Bugscope Teamwe ask that the teacher send us the bugs well in advance, so we have up to a week to prep the bugs. but often we'll get the bugs 1-2 days before the session and we have to rush the sample together. either way works. we can probably prep a sample in 1-2 hours if we had to
- TeacherThank you!
- Teacherwhat is the most unusual thing you have discovered
Bugscope Teamlots of cool things -- like earwigs often have mites on them
- Bugscope Teaminsects are pretty cool because they do many of the things we do, but differently. and they have their skeleton on the outside, which is why they have all of those tiny setae, and bristles, and spines, and trichae sticking through
- 4:33 pm
- Teacherwow! this is cool
- Teacherwhat are we looking at now?
- TeacherSpider Eyes!
- Bugscope Teamthe big things in the front are the chelicers, or chelicerae
- Teacheranyone else want to drive?
- Bugscope Teamthey open left and right and at the base are the fangs, which point inward
- Bugscope Teamspiders are soft bodied and often shrivel up quite a bit
- Teacheri was telling them at the beinning that you have very good hints on what specimans are good to collect
Bugscope Teamthe best samples for Bugscope are small, and also we think the more interesting insects/athropods are specialists, as opposed to roaches or crickets, for example
- Guesti will drive
Bugscope Teamokay, you've got control now
- Teacherany other drivers out there?
- Guestmy p presets are gone
Bugscope Teamhit refresh
- Bugscope Teamif your screen goes black or you lose the preset, try to refresh your browser, using F5
- Bugscope Teamrefresh fixes a lot of stuff. F5.
- Bugscope Teamthis is the head of a hawk moth, I think it was
- Bugscope Teamthe compound eye is as big as another moth on the stub above it
- 4:38 pm
- Bugscope Teamclick to stop!
- GuestThanks for the info on endangered bugs - it;'s hard to imagine that!
Bugscope TeamYeah, there are so many of the more annoying insects it's weird to think some might actually go instinct. There may be more endangered than we think - there may be more insects almost extinct in places like the rain forest where we don't have as much information.
- Bugscope Teamcool good save
- Bugscope Teamthis is the wing, part of the wing, of the hawk moth
- Bugscope Teamwhen using click to drive: click once to start moving, then you MUST click again to stop, or else it'll keep moving
- Bugscope Teamusing click to center is much easier
- Bugscope Teamif you get lost, just click on any preset and it'll move there
- Teachersomehow, you are capturing all of this, correct?
Bugscope Teamyep, your bugscope member page has all the images and chat from this session: http://bugscope.beckman.illinois.edu/members/2009-144
- Bugscope Teamthe stub is only 1.75 inches in diameter, which is why we like small critters.
- Teachervery nice!
- Teacheri'll share it with the teachers
- Bugscope Teamwe keep a database of all the images and chat, for every single session, and that is available to the teacher and class anytime after their session
- Bugscope Teamthis is the claw of one of the fruit flies
- Teachertell us about your research and now you got interested in your field
Bugscope TeamI was always interested in biology, and after taking a course in undergrad, insects seem like they are really cool and do a lot of neat things while also serving as a great model for biological studies. Then after a couple of internships and jobs, I decided not only did I enjoy the lab portions, the outdoor field work is also really awesome, and here i am~
Bugscope TeamI'm still figuring out what I want to do, but I am planning to look at mating behavior of longhorned beetles. I got interested from a high school class about insects. They're so weird, almost like little aliens, I was just fascinated by it.
- Bugscope Teamthere are brochosomes on the tip of the claw
- Bugscope Teamyeah Becca and Joe...
- 4:44 pm
- Bugscope Teamscott is going to get a good view of the brochosomes now
- Teachertell us what is the best way for the teachers to send/ship the bugs
Bugscope Teamit's all documented on our website, in complete detail. but bascially: freeze the bugs in an airtight jar of some kind, then ship in a film canister in some toilet paper or something like that
- Bugscope Teamscott is an electron microscopist, he's an expert at using the scope
- Guestwhat is an Ommatidia
- Bugscope Teamthese are some of the ommatidia -- the indivdual facets of the eye
- Bugscope Teamour website contains everything a teacher should need to know: bugscope.beckman.illinois.edu, however we will answer any questions they might have as well: firstname.lastname@example.org
- Bugscope Teamthis is the other skeeter
- Bugscope Teama compound eye is made up of hundred of individual facets, each with a lens in it. those facets are called ommatidia
- Bugscope Teamthis is one of the palps
- Guestanyone want to drive
- Teachercan you show us a few more things?
- Bugscope TeamThis is cool. This is one of the true bugs (Hemiptera) on the stub today
- 4:49 pm
- Teacherhe needs a cool name :)
- Guestare the large circles to the side the eyes
- Bugscope Teamtrue bugs have piercing/sucking mouthparts like this, and they have a particular arrangement or orientation of the wings/elytra that characterizes them as well
- Bugscope Teamyes
- Teacherany other questions from the group?
- Bugscope Teamcompound eyes
- Bugscope Teamand you can see the bases of the antennae
- Bugscope Teamthis shows part of the piercing/cutting part of the mouthparts
- Guestwhat are we looking at
- Bugscope Teamoh and a little hole there...
- Teacherwhat is the dark hole area?
Bugscope Teamheh, that's where a pin was stick into the bug to hold it down
Bugscope Teamlooks like it's been pinned?
- Bugscope Teamthis is the thorax of the true bug.
- Teacherany final questions from the group?
- GuestI see a preset called Aztec salt?
Bugscope Teamyep, it's salt from Wendy's, it has a cool structure to it
- Bugscope Teamit's one of those 'Terminator' wounds
- Teacheras in the fast food Wendy's?
Bugscope Teamyep, the "where's the beef" place
- 4:54 pm
- Bugscope Teamwe think it looks like cool Aztec carving
- Bugscope Teamit does!
- Bugscope Teamquality is their recipe!
- Bugscope TeamI've never looked at salt before - does salt from different places look different?
- Bugscope Teamwe put it in there for kids, just to give them something different. and most can ID with wendy's
- Bugscope Teamthe sodium chloride crystals are cubic, but from Wendy's they have that particular shape
- GuestWhat would be a good number of bugs to send for a class?
Bugscope Team11 or 12, depends on the size
Bugscope Teamwell, it depends on the size, we have a 1.5 inch stub to put bugs on. so 5-8 small bugs would work fine
- Teacherthanks for doing this session! pretty fascinating
- Bugscope Teamthis is an aphid!
- Bugscope TeamThank you Gerri!
- Bugscope Teamremember your member page, all the chat and images are stored there: http://bugscope.beckman.illinois.edu/members/2009-144
- Bugscope TeamNo problem, I had fun, too!
- Bugscope TeamYou can see the cornicles.
- Bugscope Teamlike little jet exhausts
- Bugscope Team1.75-inch stub...
- Teacherthanks so much
- Teacheri'll get my evaluation done
- Bugscope TeamSee you next time!
- Bugscope TeamThank You Everyone!
- Bugscope Teambye!
- Teacherget ready for more texas teachers to sign up!
- Bugscope Teamyou are very welcome gerri
- 4:59 pm
- Bugscope Teamover and out!
- Bugscope TeamBye!
- Bugscope Teamokay, closing down the session, nice session everyone
