- 2:42 pm
- Bugscope Teamwaiting for the sample to pump down
- Bugscope Teamnot too slow, yet
- 2:56 pm
- Bugscope Team1.4...
- 3:03 pm
- 3:08 pm
- Bugscope Teamhello!
- TeacherSee you in about 20 minutes
- Bugscope Teamsee you :)
- 3:14 pm
- 3:19 pm
- 3:25 pm
- 3:32 pm
- 3:37 pm
- Bugscope Teamthis is really interesting, Dr K
- Bugscope Teamwe found either baby sowbugs or some kind of alien
- Bugscope Teamor perhaps they are mites -- we've nevair seen mites on roly polys
- Bugscope Teamthey're inside the torn part of the sowbug rolypoly woodlouse
- 3:43 pm
- TeacherWhat is the bug hanging out of the bug? HUH?
Bugscope Teamnever seen anything quite like that before
- Bugscope Teamthis looks like a mite, to the left center
- Bugscope Teamoops I mean right center
- Bugscope Teamnudist coveries every day
- Bugscope Teamthese are mold spores
- Bugscope Teamfairly high mag for Bugscope
- Bugscope Teamthey're resting on an insect scale, with the ridges on it
- Teachernudist coveries every day?
- Bugscope Teamnew discoveries yeah
- 3:48 pm
- Bugscope Teamsorry
- Bugscope Teamnow you can see where we were
- Bugscope Teamthe flat strands on the surface of the body are fungal hyphae
- Bugscope TeamMiles! Where are you?
- Bugscope Teamthis is a female earwig
- Bugscope Teamyou can tell because its cercopods, which we can't see yet (to the south) are straight, not curved
- GuestIn class at CSUEB on my own computer
Bugscope Teamtotally cool
- Bugscope Teamearwigs often have mites on them as well, but we haven
- Bugscope Team't see any yet
- GuestWhat are these hairs and why does it need them?
- 3:53 pm
- Bugscope Teamthe hairs are called 'setae,' pronounced see-tee, and they are often sensory
- GuestAre they on the whole body, or just the legs?
- Teachercanyou give scope control to Miles?
- Bugscope Teamthey help with proprioception, sensing touch and wind/air currents, sensing chemicals in the air, thermosensing...
- Bugscope Teamthe setae help insects sense their environment
- Bugscope Teamthis is the head of a honeybee
- Bugscope Teambees wasps and ants are related
- Bugscope TeamHymenoptera
- Guestwhat ar?
- Bugscope Teamthis is the compound eye of the honeybee
- Bugscope Teamcovered with setae
- Guestwhat are the curly things on the left?
Bugscope Teamout of the image now?
- Bugscope Teamthey cover the proboscis
- GuestPlease give control back to csueb
- 3:59 pm
- GuestIs the probiscis its jaw?
Bugscope Teamthe proboscis is the tongue
- Bugscope Teammandibles are jaws, and I believe this has separate mandibles
- Guestwhy do they need it to be covered?
- Teacherthis a new group
- Bugscope Teamthis is kind of cool
- Bugscope Teamyou can see why isopods are called 'isopods'
- Guestis the bee covered in dust particles?
Bugscope Teamyeah there is a lot of juju on it
- Bugscope Teaminsects cannot help but get covered with stuff after they die, and when they are kept in enclosed spaces when they're still damp, they'll get mold. they'll get mold anyway
- 4:04 pm
- Teacherwhats a sowbug?
Bugscope Teamit's a crustacean, actually
- Bugscope Teamsowbug, pillbug, rolpoly, woodlouse
- Bugscope Teamthey're not always the same species, however
- Bugscope Teaminsects do not have skin, like we do, with nerve endings in it, nor do they have noses, and they usually do not have ears
Bugscope TeamThis is true. Insects don't have what we think of as ears, but they do usually can sense sound to a degree. Some use tympanal organs (which is akin to our ear drums), and other sense changes to the vibrations in the air with setae. The sound is then processed in the Johnston's organ.
- Teacherwhat makes it a crustacean?
Bugscope Teamit has gills, for one; and it is not an insect since it has more than six legs as an adult
- Bugscope Teamof course not being an insect does not automatically make you a crustacean
- Bugscope Teamwhat is interesting about this one is that it seems to have some other critters coming out of it
- Bugscope Teamah this is cool
- Bugscope Teamthese are hooks called hamuli that connect the fore- and hindwings in flight
- Bugscope Teambees and wasps both have four wings
- 4:09 pm
- Teacherwhat part of a honeybee is that?
Bugscope Teamthe wings
Bugscope Teamthey hook the two wings together, so that when the bees fly the fore and hind wings are in sync
- Teacherare the wings attached to those rings?
Bugscope Teamthe hamuli are on the leading edge of the hindwings and attach to the trailing edge of the forewing
- Bugscope Teamit means that when you fly you have the benefit of two wings but when you crawl into a hive or other small space you don't have these mondo bigboy wings to deal with
- Teacherdidn't know such intricate physical mechanism was involved in moving the wings
Bugscope Teamit's really cool -- insects have to do some of the same things we do but in a different way. we have to collect frequent flier miles...
- Bugscope Teamthis is one of the housefly's claws, one set of claws for each of the six legs
- TeacherHow many claws does a housefly have?
- Teacher6 I got it
- Teacherare the clas attached to the legs? or are they separate?
Bugscope Teamthey're at the distal ends of the legs
- Bugscope Teamsome but not all insects have working claws that open and close, and a tendon called an unguitractor that makes that work
- 4:14 pm
- Bugscope Teamthis is totally cool as well
- Bugscope Teamstinkbugs have two of these openings on the ventral side of the body that let the 'stink' out
- Teacherso what is the web thing
Bugscope Teampart of that is to keep particles from going into the opening
- Bugscope Teamthe claws, which are tarsi, or the final tarsomere, also have a pad called a pulvillus on them that has sticky setae (tenent setae) that make it possible for the fly to walk on the ceiling, for example
Bugscope Teamthe way they are able to attach to things is pretty cool, it's partly due to adhesive substances, and also van der waals forces (which is a relatively weak type of molecular bond)
- Teacherdo the gland regulate something?
Bugscope Teamthe glands in this case produce the stink that discourages birds and mice and other insects from eating them'
- Bugscope Teamnow you can see where we were, between I think the 1st and 2nd legs on each side
- Bugscope Teamit's a girl!
- 4:19 pm
- Bugscope Teamyou can see the compound eyes, which cover the head
- Teacherhow do you know it's a girl?
Bugscope Teammales have ornate and frilly antennae, whereas those of females are plain
- Bugscope Teamthe things that look like donuts are called pedicels, and they are the bases of the antennae
- Bugscope Teammosquitoes, moths, butterflies, and silverfish, along with few other insects, have scales
- Teacherwhy does it look smushed?
Bugscope Teamit dried after it died, and the normally bulbous eyes kind of deflated
- Bugscope Teamhere you can see some scales
- Teacheris this the eye?
Bugscope Teamthe larger portion that looks like a collapsed dome is the compound eye.
Bugscope Teamthe compound eye is made of many ommatidium
- Bugscope Teamoops not now
- Bugscope Teamthis is the face of the sowbug
- Bugscope Teamyou can barely make out the eye on one side
- Teacherwhere is its eye at?
Bugscope TeamI will drive there
- Bugscope Teamthere.
- Teachercan you also help us center it?
- 4:24 pm
- Bugscope Teamthey have less complex compound eyes
- Bugscope Teamit's peering through that small slit.
- Teacheris the eye in between the crevices?
Bugscope Teamyes it is!
- Bugscope Teamwhen we mount critters for Bugscope we almost always mount them ventral side up
- Teacherhow many eyes does a sow bug have?
Bugscope Team2 compound eyes.
- TeacherWe are going to log out in a few - anything else to share?
- TeacherHello = Dr. Korb here again. The students did a great job today! Hello to Jose too :) Are you a new Bugscope member?
Bugscope TeamHi! i'm an entomology student here at the U of I
Bugscope Teami'm in and out because of field work and work scheduling.
- Bugscope TeamJose has been around for a while but is a genuine entomologist, often quite busy
- TeacherOh very cool , Jose!! Thanks for chatting with us!!
Bugscope Teamno problem it was fun!
- Bugscope TeamCate made today's sample and helped set up but had to retrieve her kids.
- 4:30 pm
- Bugscope Teamand the sowbugs eyes mostly face the dorsal side
Bugscope Teamif you look from the top down, it looks like someone stuck a couple of mulberries to the side of their heads. those are the eyes.
Bugscope Teamyeah they're actually on the sides, as Joe says
- TeacherTake care~! Tahnks to Cate too! Talk to you later! MK
- TeacherWhat does a busy entomologist do?
Bugscope Teamget covered in ticks and mosquito bites.
Bugscope TeamI work with longhorned beetles and their pheromones and other olfactory senses.
- Bugscope Teamusually I am Scot and he is Joe but at some point our names were sucked away by the software and we haven't recovered them yet.
- Bugscope Teamdude you could save some of those ticks for us... I know it's not the first thing you're thinking of
Bugscope Teami have a bunch of stuff for you actually. just been lazy in bringing them up.
- Bugscope TeamThank You!
- Bugscope TeamThanks, Joe!
- Bugscope TeamGood to see you. Over and out..
