- Bugscope Teampresets done, we are ready
- Bugscope Teamhi mrs. b!
- Bugscope Teamwelcome to bugscope
- Bugscope Teami've just unlocked the session
- Bugscope Teamyou now have complete control of the scope-aroni
- Bugscope TeamGood idea Holmes.
- TeacherHi all...Gaye-Lynn here again, Bernie is still out. The girls should be here shortly...
- Bugscope Teamokay, hi gaye-lynn
- Bugscope TeamThis beetle lost the tip of one of his/her antennae.
- TeacherWe are on a mission to find insect adaptations today...
- Bugscope Teamewww, sounds interesting
- Bugscope Teamgaye-lynn, just let us know if you have any questions or comments, we are here to help...
- 3:26 pm
- Bugscope TeamPete! Yay!
- Bugscope TeamThanks for getting on.
- GuestSweet presets
- GuestHi, yeah, this looks cool
- Bugscope Teamcate made the presets today
- Bugscope Teamwith your helpalex
- Bugscope TeamPete, in the lower right corner of the screen there is a little scroll bar with presets...including mystery wasp
- Bugscope TeamThanks you guys. We want to know what the spider bombs are -- they look like balls of web, sort of.
- TeacherWhat is in the center of the screen right now?
- Bugscope TeamHi Suzi!
- Bugscope Teamthe busted antenna
- GuestHi Scott
- Bugscope Teamthe busted antenna on the face of a june bug
- Bugscope Teamwe are looking at the underside of a beetle head
- Bugscope Teamthe beetle antenna is missing its last segments, on that side
- Bugscope TeamNow we are looking at a close up of the side of the beetle's mouth
- Teacherwhat are the thorns?
Bugscope TeamThose are not thorns, they are setae. Setae is what we call the "hairs" on insects. The setae help the beetle to sense its environment
Bugscope Teamthorns are most likely "setae" or hair-like structures that stick out from the exoskeleton of the insect. setae (SEA-TEE) help the insect to sense it's enviornment.
- Bugscope TeamThose are probably mechanosensory setae.
- Bugscope TeamThey certainly do look like thorns though!
- 3:32 pm
- Bugscope TeamOh this scale didn't maintain its focus.
- Bugscope Teamim sad ;_;
- Bugscope Teamnice view
- Bugscope Teamyou can see how the scales are 3D.
- Teacherwhat kind of butterfly is this
Bugscope Teami think it was a moarch
- Bugscope Teammonarch*
- Bugscope Teamthis may have been from a Monarch.
- Bugscope TeamBut when we see scales that have openings like this in the past they have been from white wings.
- Teacherdo the scales on the wings make the butterfly waterproof?
Bugscope TeamNot necessarily. The scales make the butterfly slippery--so that it can escape predators. It just loses a lot of scales and is able to escape when a predator grabs it
- Bugscope TeamAnd of course you will need to focus a little.
- Bugscope Teamfocus can be tricky, if it's not working try the other direction...
- 3:38 pm
- Bugscope Teamspiders sometimes do not like the taste of butterflies and will just cut them out of their webs if they do not escape by themselves.
- Bugscope TeamDeus ex machina focussing.
- Bugscope Teamthere is still a little charging from the electron beam because we are at pretty high mag and putting a lot of energy in this one place.
- Teacherhow long do butterflies live?
Bugscope TeamMost butterflies will live from the beginning to spring to the end of the summer.
- Bugscope Teamsee how the scale is drifting?
- Teacheryes
- Teachertell me more
- Bugscope Teamthe electron beam is impinging on the scale, and we are at pretty high mag...
- Bugscope TeamThere are several species of butterflies and more species of moths that can have two generations per summer
- Bugscope Teamthis is the claw of a ladybug
- 3:43 pm
- Bugscope Teambelow the claw, there is the pulvillus where tenent setae are found
- Teacherwhat are the bumby things
Bugscope Teamthere are ridges, and then there is dirt or some other sort of debris
- Bugscope Teamladybugs are more commonly called ladybeetles by scientists (entomologists), right annie?
- Bugscope Teamscott calls the debris juju
- Bugscope TeamThe juju can be dirt, fungus, or oils and lipids that are naturally present on the insect's cuticle
- Teacherwhat do lady bugs eat?
Bugscope Teamladybugs feed on other insects like aphids or scale insects, because of that they are considered to be a "useful" insect
- Teacherare their claws poisonous?
Bugscope Teamnot that I'm aware of, but they can secrete a substance that makes them taste/smell bad
Bugscope TeamNope...I don't know of any insect with poisonous claws. Sometimes the claws can scratch skin, but genreally thye are pretty harmless
- Bugscope TeamLady bugs eat other bugs.
- 3:49 pm
- Bugscope Teamother smaller bugs
- Bugscope Teamnice imaging
- Bugscope Teamyeah this looks good, nice job
- Teacherare the thorney things setae?
Bugscope Teamyes!
- Bugscope Teamthose are also setae, and you can tell that they go through the cuticle to the nervous system.
- Bugscope Teamsome setae are chemosensory and some are mechanosensory
- TeacherWhat do the round things thAT LOOK LIKE OVALS DO FOR THE INSECT
- 3:54 pm
- Bugscope TeamDrive us to them?
- TeacherdID YOU POZITIN THER LIGES THAT WAY
- Bugscope Teamthe legs folded that way naturally
- Bugscope Teamokay now we are imaging the head.
- Bugscope Teamyou can see lots of palps, mandibular and maxillary
- Bugscope Teamand you can see the eyes, on either side, and the mouth, and the jaws
- Bugscope Teamand notice the compound eyes on the far left and right
- Bugscope Teamthe palps are kind of like tiny limbs that help the ladybug feed and also taste its food
- Bugscope Teamyou can see now that the head can pivot a little
- Bugscope Teamyeah like a turtle as Cate says
- Bugscope Teamlooks like a turtle hehe
- Bugscope TeamBe sure to try some of the other presets today...
- 3:59 pm
- TeacherdOES THE WASP STINGER FALL OF WHEN IT STINGS
Bugscope TeamThis is a parasitic wasp, that lays its eggs in the eggs or larvae of other insects
- Bugscope Teamno they can sting again
- Bugscope Teamyeah thats whats bad about wasps, they can sting you multiple times
- Bugscope Teamand you can tell by the shape of the part that cuts into your skin -- the wasp can get it back out easily.
- Bugscope Teamyou cansee the serrations, like a steak knife
- Bugscope Teamso really this is an ovipositor/stinger
- TeacherThat is cool
- Bugscope TeamThe serrations help the stinger/ovipositor to stick in the host while the wasp is laying and egg in it
- Bugscope Teamyup. Wasps like this are considered beneficial because they can kill harmful insects that damage crops
- Bugscope Teamif it had heavily recurved serrations it would be harder to remove
- Teachertell me more about this image...
- Bugscope Teamthe ball that was in the image was a seed
- Bugscope Teamwe are on a small beetle right now
- Bugscope Teamwell, this is a beetle with a small seed on it. we often find small things on insects like pollen or mold spores, sometimes seeds and such.
- 4:04 pm
- Bugscope Teamyou are at pretty high magnification now, if you lower the mag you might get a better look at the whole insect
- Teacherdo you know what kind of seed this one was.
- Bugscope Teamno, that would be really hard to ID
- Bugscope Teamhave to be some kind of seed specialist
- Bugscope Teamwe don't know; we see a lot of things like this that we are not equipped to recognize
- Bugscope Teamoh and here is another one...
- Bugscope Teamnow this is a cool image
- Bugscope Teamtake the mag lower so we can see where we are, please...
- Bugscope Teamscott calls them spider bombs, thinking this is wht some spiders throw at prey
- Bugscope Teamthese are spider silk balls, web bombs!
- Bugscope Teamwow thanks!
- Bugscope Teamawesome driving
- Bugscope Teamnice looking spider Cate found in the collection today
- Bugscope Teamyou can see the spinnerets
- Bugscope Teamand the head to the NE
- Bugscope Teamyou can drive up there if you want
- Bugscope Teamwow, notice how it's front legs are so much longer than it's rear ones.
- Bugscope Teamspiders eat their web and recycle it
- Bugscope Teamthe spinnerets are what the web silk come out of
- Bugscope TeamI have not noticed Spiderman doing that
- Bugscope Teamweb silk is made primarily out of protein
- Teacherhow do they do that.
- Bugscope Teamwell spiderman doesnt shoot webs from his abdomen
- Bugscope Teamif spiders get stuck in their own web they can eat their way out
- Bugscope Teamyeah that's another thing -- Spiderman does not have spinnerets
- Bugscope Teamsometimes you can see the fangs and at the tips, the poison pores
- Bugscope Teamspiderman had handerets
- 4:09 pm
- Teachercan other animals eat their way out
Bugscope Teamsome can...or they can struggle long enough to escape or they can lose body parts
- Bugscope Teamor eight legs or eight eyes
- Bugscope Teamhmm, good question
- Bugscope Teamspiders can jettison their limbs if they want to, like if they feel poison seeping into a leg they can autotomize that leg -- just let it go before the poison reaches the body
- Teacheris thisthe spineret
- Bugscope Teamyep!
- Bugscope Teamthat's why it is helpful to have tiny loose scales if you get caught in a web.
- Bugscope Teamit's an odd spelling: spinnerete
- Bugscope Teamspiders can spoin silk that is not sticky
- Bugscope Teampsin
- Bugscope Teamspin
- Bugscope Teamgot it
- Bugscope Teamthey can choose whether it will be sitcky or not
- Bugscope Teamsticky
- Bugscope Teamthe brochosome is to the far left
- Teachertell us more
Bugscope Teamsome spiders live underwater, in little air bubbles that they make themselves
- 4:15 pm
- Bugscope Teambrochosomes are made by leafhoppers
- Bugscope Teambrochosomes are tiny soccerball-like waxy pellets that are produced, as far as we know, onlyby leafhoppers
- Bugscope Teamwhich means this spider ate some leafhoppers as a snack
- Bugscope Teamspiders almost always have those cool-looking 3D setae
- Bugscope TeamLeafhopper dust their egg masses with brochosomes to protect them from drying out
- Bugscope Teamit's called an 'anointing' behavior
- Bugscope Teamthe bumps are its compound eye
- Bugscope Teamoops one antenna is gone...
- Bugscope Teamsome spiders show social behavior and make webs together and live in large colonies
- Teacherpoor ant
- 4:20 pm
- Bugscope TeamI have a friend that studies social spiders...and black widows
- Bugscope Teamif you look at the legs, a couple of the forelegs will have combs on them
- Bugscope Teamthe most common social spider is the tangle web spider, which can live in colonies of up to 50 thousand spiders! think of that, 50 thousand spiders all over the place...
- Bugscope Teamblack widows look like plastic -- they are shiny and pretty. one of my friends picked one up and brought it to her mother, when she was little, 'cause it was so pretty
- Teacher i thought we were tlking about an ant
- Bugscope Teamalex likes spiders
- Bugscope Teamyeah, sorry, took me a long time to type, i was stuck on stella, i mean spiders...
- Bugscope Teamants are much more social than spiders
- Teacherit has a polp
- Bugscope Teamyes, i go out to dinner with ants all the time scott
- Bugscope Teamall ants are social, only a few species of spiders are social
- Bugscope TeamAlex takes a personal interest in the insectss
- Bugscope TeamYeah Annie I was going to ask if there were solitary ants
- Bugscope Teamants are cool, their mouths look so busy, like they are in the middle of a snack
- Bugscope Teamnope, none.
- Bugscope Teammaybe they are solitary and secretive...
- Bugscope Teammaybe....
- Bugscope Teamyou are kind to let me think it would be possible
- Bugscope Teamthis is the fruit fly mouth
- Bugscope Teamit is a little dry
- Bugscope TeamI guess it is possible
- 4:25 pm
- Teacherwhat makes a fruit fly different from a fly.
- Bugscope Teamfruit flies are much smaller than house flies
- Bugscope TeamYou can see both halteres.
- Teacherhow much fruit would a fruit fly fly if a fruit fly could fly fruit
- Bugscope Teamnone
- Bugscope Team;)
- Teacherlol
- Bugscope Teamthe halteres are the modified second set of wings in dipterans that balance the motion of the two wings
- Bugscope Teamhow much chocolate would an alex eat chocolate if alex could eat as much chocolate as he could
- Bugscope Teamhalteres look like tiny boxers' speedbags
- Bugscope Teamand they move opposite the movement of the wings
- Bugscope Teamyou can see them if you take the mag up closer
- Bugscope Teamlike a speedbag moves the oposite way from your fist
- TeacherHi guys...Gaye-Lynn here thank you for the great session we are going to have to go now.
