- 3:19pm
- Bugscope Team presets done, we are ready
- Bugscope Team hi mrs. b!
- Bugscope Team welcome to bugscope
- Bugscope Team i've just unlocked the session
- Bugscope Team you now have complete control of the scope-aroni
- Bugscope Team Good idea Holmes.
- Teacher Hi all...Gaye-Lynn here again, Bernie is still out. The girls should be here shortly...
- Bugscope Team okay, hi gaye-lynn
- Bugscope Team This beetle lost the tip of one of his/her antennae.
- Teacher We are on a mission to find insect adaptations today...
- Bugscope Team ewww, sounds interesting
- Bugscope Team gaye-lynn, just let us know if you have any questions or comments, we are here to help...
- 3:26pm
- Bugscope Team Pete! Yay!
- Bugscope Team Thanks for getting on.
- Guest Sweet presets
- Guest Hi, yeah, this looks cool
- Bugscope Team cate made the presets today
- Bugscope Team with your helpalex
- Bugscope Team Pete, in the lower right corner of the screen there is a little scroll bar with presets...including mystery wasp
- Bugscope Team Thanks you guys. We want to know what the spider bombs are -- they look like balls of web, sort of.
- Teacher What is in the center of the screen right now?
- Bugscope Team Hi Suzi!
- Bugscope Team the busted antenna
- Guest Hi Scott
- Bugscope Team the busted antenna on the face of a june bug
- Bugscope Team we are looking at the underside of a beetle head
- Bugscope Team the beetle antenna is missing its last segments, on that side
- Bugscope Team Now we are looking at a close up of the side of the beetle's mouth
- Teacher what are the thorns?
Bugscope Team Those 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 Team thorns 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 Team Those are probably mechanosensory setae.
- Bugscope Team They certainly do look like thorns though!
- 3:32pm
- Bugscope Team Oh this scale didn't maintain its focus.
- Bugscope Team im sad ;_;
- Bugscope Team nice view
- Bugscope Team you can see how the scales are 3D.
- Teacher what kind of butterfly is this
Bugscope Team i think it was a moarch
- Bugscope Team monarch*
- Bugscope Team this may have been from a Monarch.
- Bugscope Team But when we see scales that have openings like this in the past they have been from white wings.
- Teacher do the scales on the wings make the butterfly waterproof?
Bugscope Team Not 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 Team And of course you will need to focus a little.
- Bugscope Team focus can be tricky, if it's not working try the other direction...
- 3:38pm
- Bugscope Team spiders 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 Team Deus ex machina focussing.
- Bugscope Team there 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.
- Teacher how long do butterflies live?
Bugscope Team Most butterflies will live from the beginning to spring to the end of the summer.
- Bugscope Team see how the scale is drifting?
- Teacher yes
- Teacher tell me more
- Bugscope Team the electron beam is impinging on the scale, and we are at pretty high mag...
- Bugscope Team There are several species of butterflies and more species of moths that can have two generations per summer
- Bugscope Team this is the claw of a ladybug
- 3:43pm
- Bugscope Team below the claw, there is the pulvillus where tenent setae are found
- Teacher what are the bumby things
Bugscope Team there are ridges, and then there is dirt or some other sort of debris
- Bugscope Team ladybugs are more commonly called ladybeetles by scientists (entomologists), right annie?
- Bugscope Team scott calls the debris juju
- Bugscope Team The juju can be dirt, fungus, or oils and lipids that are naturally present on the insect's cuticle
- Teacher what do lady bugs eat?
Bugscope Team ladybugs feed on other insects like aphids or scale insects, because of that they are considered to be a "useful" insect
- Teacher are their claws poisonous?
Bugscope Team not that I'm aware of, but they can secrete a substance that makes them taste/smell bad
Bugscope Team Nope...I don't know of any insect with poisonous claws. Sometimes the claws can scratch skin, but genreally thye are pretty harmless
- Bugscope Team Lady bugs eat other bugs.
- 3:49pm
- Bugscope Team other smaller bugs
- Bugscope Team nice imaging
- Bugscope Team yeah this looks good, nice job
- Teacher are the thorney things setae?
Bugscope Team yes!
- Bugscope Team those are also setae, and you can tell that they go through the cuticle to the nervous system.
- Bugscope Team some setae are chemosensory and some are mechanosensory
- Teacher What do the round things thAT LOOK LIKE OVALS DO FOR THE INSECT
- 3:54pm
- Bugscope Team Drive us to them?
- Teacher dID YOU POZITIN THER LIGES THAT WAY
- Bugscope Team the legs folded that way naturally
- Bugscope Team okay now we are imaging the head.
- Bugscope Team you can see lots of palps, mandibular and maxillary
- Bugscope Team and you can see the eyes, on either side, and the mouth, and the jaws
- Bugscope Team and notice the compound eyes on the far left and right
- Bugscope Team the palps are kind of like tiny limbs that help the ladybug feed and also taste its food
- Bugscope Team you can see now that the head can pivot a little
- Bugscope Team yeah like a turtle as Cate says
- Bugscope Team looks like a turtle hehe
- Bugscope Team Be sure to try some of the other presets today...
- 3:59pm
- Teacher dOES THE WASP STINGER FALL OF WHEN IT STINGS
Bugscope Team This is a parasitic wasp, that lays its eggs in the eggs or larvae of other insects
- Bugscope Team no they can sting again
- Bugscope Team yeah thats whats bad about wasps, they can sting you multiple times
- Bugscope Team and you can tell by the shape of the part that cuts into your skin -- the wasp can get it back out easily.
- Bugscope Team you cansee the serrations, like a steak knife
- Bugscope Team so really this is an ovipositor/stinger
- Teacher That is cool
- Bugscope Team The serrations help the stinger/ovipositor to stick in the host while the wasp is laying and egg in it
- Bugscope Team yup. Wasps like this are considered beneficial because they can kill harmful insects that damage crops
- Bugscope Team if it had heavily recurved serrations it would be harder to remove
- Teacher tell me more about this image...
- Bugscope Team the ball that was in the image was a seed
- Bugscope Team we are on a small beetle right now
- Bugscope Team well, 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.
- 4:04pm
- Bugscope Team you are at pretty high magnification now, if you lower the mag you might get a better look at the whole insect
- Teacher do you know what kind of seed this one was.
- Bugscope Team no, that would be really hard to ID
- Bugscope Team have to be some kind of seed specialist
- Bugscope Team we don't know; we see a lot of things like this that we are not equipped to recognize
- Bugscope Team oh and here is another one...
- Bugscope Team now this is a cool image
- Bugscope Team take the mag lower so we can see where we are, please...
- Bugscope Team scott calls them spider bombs, thinking this is wht some spiders throw at prey
- Bugscope Team these are spider silk balls, web bombs!
- Bugscope Team wow thanks!
- Bugscope Team awesome driving
- Bugscope Team nice looking spider Cate found in the collection today
- Bugscope Team you can see the spinnerets
- Bugscope Team and the head to the NE
- Bugscope Team you can drive up there if you want
- Bugscope Team wow, notice how it's front legs are so much longer than it's rear ones.
- Bugscope Team spiders eat their web and recycle it
- Bugscope Team the spinnerets are what the web silk come out of
- Bugscope Team I have not noticed Spiderman doing that
- Bugscope Team web silk is made primarily out of protein
- Teacher how do they do that.
- Bugscope Team well spiderman doesnt shoot webs from his abdomen
- Bugscope Team if spiders get stuck in their own web they can eat their way out
- Bugscope Team yeah that's another thing -- Spiderman does not have spinnerets
- Bugscope Team sometimes you can see the fangs and at the tips, the poison pores
- Bugscope Team spiderman had handerets
- 4:09pm
- Teacher can other animals eat their way out
Bugscope Team some can...or they can struggle long enough to escape or they can lose body parts
- Bugscope Team or eight legs or eight eyes
- Bugscope Team hmm, good question
- Bugscope Team spiders 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
- Teacher is thisthe spineret
- Bugscope Team yep!
- Bugscope Team that's why it is helpful to have tiny loose scales if you get caught in a web.
- Bugscope Team it's an odd spelling: spinnerete
- Bugscope Team spiders can spoin silk that is not sticky
- Bugscope Team psin
- Bugscope Team spin
- Bugscope Team got it
- Bugscope Team they can choose whether it will be sitcky or not
- Bugscope Team sticky
- Bugscope Team the brochosome is to the far left
- Teacher tell us more
Bugscope Team some spiders live underwater, in little air bubbles that they make themselves
- 4:15pm
- Bugscope Team brochosomes are made by leafhoppers
- Bugscope Team brochosomes are tiny soccerball-like waxy pellets that are produced, as far as we know, onlyby leafhoppers
- Bugscope Team which means this spider ate some leafhoppers as a snack
- Bugscope Team spiders almost always have those cool-looking 3D setae
- Bugscope Team Leafhopper dust their egg masses with brochosomes to protect them from drying out
- Bugscope Team it's called an 'anointing' behavior
- Bugscope Team the bumps are its compound eye
- Bugscope Team oops one antenna is gone...
- Bugscope Team some spiders show social behavior and make webs together and live in large colonies
- Teacher poor ant
- 4:20pm
- Bugscope Team I have a friend that studies social spiders...and black widows
- Bugscope Team if you look at the legs, a couple of the forelegs will have combs on them
- Bugscope Team the 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 Team black 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 Team alex likes spiders
- Bugscope Team yeah, sorry, took me a long time to type, i was stuck on stella, i mean spiders...
- Bugscope Team ants are much more social than spiders
- Teacher it has a polp
- Bugscope Team yes, i go out to dinner with ants all the time scott
- Bugscope Team all ants are social, only a few species of spiders are social
- Bugscope Team Alex takes a personal interest in the insectss
- Bugscope Team Yeah Annie I was going to ask if there were solitary ants
- Bugscope Team ants are cool, their mouths look so busy, like they are in the middle of a snack
- Bugscope Team nope, none.
- Bugscope Team maybe they are solitary and secretive...
- Bugscope Team maybe....
- Bugscope Team you are kind to let me think it would be possible
- Bugscope Team this is the fruit fly mouth
- Bugscope Team it is a little dry
- Bugscope Team I guess it is possible
- 4:25pm
- Teacher what makes a fruit fly different from a fly.
- Bugscope Team fruit flies are much smaller than house flies
- Bugscope Team You can see both halteres.
- Teacher how much fruit would a fruit fly fly if a fruit fly could fly fruit
- Bugscope Team none
- Bugscope Team ;)
- Teacher lol
- Bugscope Team the halteres are the modified second set of wings in dipterans that balance the motion of the two wings
- Bugscope Team how much chocolate would an alex eat chocolate if alex could eat as much chocolate as he could
- Bugscope Team halteres look like tiny boxers' speedbags
- Bugscope Team and they move opposite the movement of the wings
- Bugscope Team you can see them if you take the mag up closer
- Bugscope Team like a speedbag moves the oposite way from your fist
- Teacher Hi guys...Gaye-Lynn here thank you for the great session we are going to have to go now.
- Bugscope Team Ohhh....
- Bugscope Team Thank You!
- Bugscope Team gaye-lynn, thank you for a great session!
- 4:30pm
- Bugscope Team hope to see you again sometime
- Bugscope Team Please say HI to Bernadette.
- Bugscope Team Thank you all for the good questions!
- Bugscope Team we will see you next time!
- Teacher WE will...
