- Bugscope Team waiting for the sample to pump down
- Bugscope Team not too slow, yet
- Bugscope Team 1.4...
- Bugscope Team hello!
- Teacher See you in about 20 minutes
- Bugscope Team see you :)
- Bugscope Team this is really interesting, Dr K
- Bugscope Team we found either baby sowbugs or some kind of alien
- Bugscope Team or perhaps they are mites -- we've nevair seen mites on roly polys
- Bugscope Team they're inside the torn part of the sowbug rolypoly woodlouse
- Teacher What is the bug hanging out of the bug? HUH?
Bugscope Team never seen anything quite like that before
- Bugscope Team this looks like a mite, to the left center
- Bugscope Team oops I mean right center
- Bugscope Team nudist coveries every day
- Bugscope Team these are mold spores
- Bugscope Team fairly high mag for Bugscope
- Bugscope Team they're resting on an insect scale, with the ridges on it
- Teacher nudist coveries every day?
- Bugscope Team new discoveries yeah
- Teacher funny.funny.
- Bugscope Team sorry
- Bugscope Team now you can see where we were
- Bugscope Team the flat strands on the surface of the body are fungal hyphae
- Bugscope Team Miles! Where are you?
- Bugscope Team this is a female earwig
- Bugscope Team you can tell because its cercopods, which we can't see yet (to the south) are straight, not curved
- Guest In class at CSUEB on my own computer
Bugscope Team totally cool
- Bugscope Team earwigs often have mites on them as well, but we haven
- Bugscope Team 't see any yet
- Guest What are these hairs and why does it need them?
- Bugscope Team the hairs are called 'setae,' pronounced see-tee, and they are often sensory
- Guest Are they on the whole body, or just the legs?
- Teacher canyou give scope control to Miles?
- Bugscope Team they help with proprioception, sensing touch and wind/air currents, sensing chemicals in the air, thermosensing...
- Bugscope Team the setae help insects sense their environment
- Bugscope Team this is the head of a honeybee
- Bugscope Team bees wasps and ants are related
- Bugscope Team Hymenoptera
- Guest what ar?
Bugscope Team ?
- Bugscope Team this is the compound eye of the honeybee
- Bugscope Team covered with setae
- Guest what are the curly things on the left?
Bugscope Team out of the image now?
- Bugscope Team they cover the proboscis
- Guest Please give control back to csueb
- Guest Is the probiscis its jaw?
Bugscope Team the proboscis is the tongue
- Bugscope Team mandibles are jaws, and I believe this has separate mandibles
- Guest why do they need it to be covered?
- Teacher this a new group
- Bugscope Team this is kind of cool
- Bugscope Team you can see why isopods are called 'isopods'
- Teacher hello
Bugscope Team Hello!
- Guest is the bee covered in dust particles?
Bugscope Team yeah there is a lot of juju on it
- Bugscope Team insects 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
- Teacher whats a sowbug?
Bugscope Team it's a crustacean, actually
- Bugscope Team sowbug, pillbug, rolpoly, woodlouse
- Bugscope Team they're not always the same species, however
- Bugscope Team insects 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 Team This 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.
- Teacher what makes it a crustacean?
Bugscope Team it has gills, for one; and it is not an insect since it has more than six legs as an adult
- Bugscope Team of course not being an insect does not automatically make you a crustacean
- Bugscope Team what is interesting about this one is that it seems to have some other critters coming out of it
- Bugscope Team ah this is cool
- Bugscope Team these are hooks called hamuli that connect the fore- and hindwings in flight
- Bugscope Team bees and wasps both have four wings
- Teacher what part of a honeybee is that?
Bugscope Team the wings
Bugscope Team they hook the two wings together, so that when the bees fly the fore and hind wings are in sync
- Teacher are the wings attached to those rings?
Bugscope Team the hamuli are on the leading edge of the hindwings and attach to the trailing edge of the forewing
- Bugscope Team it 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
- Teacher didn't know such intricate physical mechanism was involved in moving the wings
Bugscope Team it'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 Team this is one of the housefly's claws, one set of claws for each of the six legs
- Teacher How many claws does a housefly have?
- Teacher 6 I got it
- Teacher are the clas attached to the legs? or are they separate?
Bugscope Team they're at the distal ends of the legs
- Bugscope Team some but not all insects have working claws that open and close, and a tendon called an unguitractor that makes that work
- Bugscope Team this is totally cool as well
- Bugscope Team stinkbugs have two of these openings on the ventral side of the body that let the 'stink' out
- Teacher so what is the web thing
Bugscope Team part of that is to keep particles from going into the opening
- Bugscope Team the 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 Team the 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)
- Teacher do the gland regulate something?
Bugscope Team the glands in this case produce the stink that discourages birds and mice and other insects from eating them'
- Bugscope Team now you can see where we were, between I think the 1st and 2nd legs on each side
- Bugscope Team it's a girl!
- Bugscope Team you can see the compound eyes, which cover the head
- Teacher how do you know it's a girl?
Bugscope Team males have ornate and frilly antennae, whereas those of females are plain
- Bugscope Team the things that look like donuts are called pedicels, and they are the bases of the antennae
- Bugscope Team mosquitoes, moths, butterflies, and silverfish, along with few other insects, have scales
- Teacher why does it look smushed?
Bugscope Team it dried after it died, and the normally bulbous eyes kind of deflated
- Bugscope Team here you can see some scales
- Teacher is this the eye?
Bugscope Team yup
Bugscope Team the larger portion that looks like a collapsed dome is the compound eye.
Bugscope Team the compound eye is made of many ommatidium
- Bugscope Team oops not now
- Bugscope Team this is the face of the sowbug
- Bugscope Team you can barely make out the eye on one side
- Teacher where is its eye at?
Bugscope Team I will drive there
- Bugscope Team there.
- Teacher can you also help us center it?
Bugscope Team there!
- Bugscope Team they have less complex compound eyes
- Bugscope Team it's peering through that small slit.
Bugscope Team exactically!
- Teacher is the eye in between the crevices?
Bugscope Team yes it is!
- Bugscope Team when we mount critters for Bugscope we almost always mount them ventral side up
- Teacher how many eyes does a sow bug have?
Bugscope Team 2 compound eyes.
- Teacher We are going to log out in a few - anything else to share?
- Teacher Hello = Dr. Korb here again. The students did a great job today! Hello to Jose too :) Are you a new Bugscope member?
Bugscope Team Hi! i'm an entomology student here at the U of I
Bugscope Team i'm in and out because of field work and work scheduling.
- Bugscope Team Jose has been around for a while but is a genuine entomologist, often quite busy
- Teacher Oh very cool , Jose!! Thanks for chatting with us!!
Bugscope Team no problem it was fun!
Bugscope Team bye!
- Bugscope Team Cate made today's sample and helped set up but had to retrieve her kids.
- Bugscope Team and the sowbugs eyes mostly face the dorsal side
Bugscope Team if 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 Team yeah they're actually on the sides, as Joe says
- Teacher Take care~! Tahnks to Cate too! Talk to you later! MK
- Teacher Fuuny!
- Teacher What does a busy entomologist do?
Bugscope Team get covered in ticks and mosquito bites.
Bugscope Team I work with longhorned beetles and their pheromones and other olfactory senses.
- Bugscope Team usually 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 Team dude you could save some of those ticks for us... I know it's not the first thing you're thinking of
Bugscope Team i have a bunch of stuff for you actually. just been lazy in bringing them up.
Bugscope Team awesome
- Bugscope Team Thank You!
- Bugscope Team Thanks, Joe!
- Bugscope Team Good to see you. Over and out..
