- Bugscope Teamsample is pumping down
- 4:15 pm
- 4:21 pm
- 4:28 pm
- 4:38 pm
- 4:44 pm
- Bugscope Teamnow we're making presets
- Studentmorning scott
- Bugscope Teamhello!
- Bugscope Teamwelcome to Bugscope!
- 4:50 pm
- Studentthings are working well here
- Bugscope TeamYear6 I just gave you control. But if you can hold off on driving for a few minutes I can find some more critters for you.
- Studentkids are starting to arrive here slowly but surely
- Bugscope Teamstinger does not look good, sorry
- Studentlooks good to us
- 4:55 pm
- Bugscope TeamCate wrote 'headless wasp' on her drawing...
- Studenthello its alyssa and chealsea and indi
Bugscope Teamhello! Welcome to Bugscope!
- Studentis that the head of a spider
Bugscope Teamyes it is!
- Bugscope TeamI think there are enough presets. Kind of a strange selection today.
- Bugscope Teamso we are ready to roll
- Studentthats realy cool how u can get real close to something
Bugscope Teamwe are so lucky to have equipment like this to play around with
- 5:01 pm
- Studentis that hair
Bugscope Teamyes, in insects and similar arthropods we're s'posed to call hair setae, bristles, spines, trichae, microsetae, etc. but yes it's hair
- Studentcan we zoom in
Bugscope Teamyes if you wish
- Bugscope Teamyear6 you actually have control of the 'scope and should be able to change mag, select from the presets, etc.
- Bugscope Teamif you click on the lefthand arrow you can see the presets, and if you click on one, the 'scope will drive to that stored position on the stub
- Bugscope Teamplease let me know if for some reason it doesn't work
- Bugscope TeamI can drive if necessary
- Studentits not working you drive
- Bugscope Teamspiders have lots of sensory setae, often to help them sense vibration
- Studentwhat r those 3 little holes?
Bugscope Teamhaha I am not sure -- we are so close; they may help pick up chemical scents
- Bugscope Teamhello
- Bugscope Teamnow you can see that same seta, right in the middle of the eyes
- Bugscope TeamHi Cate!
- Bugscope TeamCate can you see this?
- Studenthi Cate......
- 5:06 pm
- Studentwhats that?
Bugscope Teamthis is the cephalothorax of the spider -- the head combined with the thorax. one thing it does is tell us that this is not an insect
- Bugscope Teamnow you can see its eight eyes
- Bugscope Teamthe two things in front, curved downward, are the chelicers, or chelicerae
- Studentthats interesting
- Bugscope Teamthe chelicerae hold the fangs, which curve inward toward each other
- Studentare they the fangs
Bugscope TeamI just went looking for the fangs but could not see them
- Bugscope Teamthe chelicerae in spiders are hollow, and house a venom gland
- Studentit is really hairy
- Bugscope Teamokay I am on another confuser now
- Studentwhats that
Bugscope Teamthis is an aphid
- Bugscope Teamaphids are true bugs -- Hemiptera
- 5:11 pm
- Bugscope Teamladybugs like to eat these pests
- Bugscope Teamthey have piercing/sucking mouthparts
- Studentthey look so weird
- Bugscope Teamthey have piercing sucking mouth parts, which the use to feed on plants
- Bugscope Teamsometimes ants are nice to them, in a way, and treat them like cattle
- Bugscope Teamthey kind of look like weird rabbits with their antenna-ears
- Studentzoom in on the sucking mouth part please
- Bugscope Teamsee the compound eyes on either side of the head?
- Bugscope Teamthe ants eat the excretion of the aphids, also called honeydew
- Bugscope Teamsome ants will aggressively protect them
- Studentwhat do you mean they treat them like cattle
Bugscope Teamthey kind of farm them and feed on the honeydew, like Jose said
- Studentcan you please zoom in on the mouth
- Bugscope Teamlike a rancher protecting cows from coyotes
- Bugscope Teamthis is it, the mouthpart
- Bugscope Teambut some aphids, instead of secreting honeydew from their cornicles, secrete this stuff that's like hotmelt glue
- Bugscope Teamthe proboscis is in the top half, right down the middle
- Bugscope Teamyes sorry it has a limb crossing in front of the tip
- Bugscope Teamthere is a leg in the way of seeing it really well i think
- Studenthow do the ants aggressively protect them
Bugscope Teamthey keep other ants and ladybugs from feeding on them
- Bugscope TeamI can likely find another aphid if you'd like, since I'm in the lab. Jose and Cate are in the Outer World, like you.
- Studentyes please
- Studentcan you tell if it is male or female
Bugscope Teamsometimes you cannot tell unless you dissect them
- 5:17 pm
- Studentwhat on earth is that
- Studentwhat are these?\
Bugscope Teamso this is another aphid. we are looking at the ventral side, and this is the tip of the proboscis
- Bugscope Teamthese are probably special hairs that help it taste
- Bugscope Teamit has chemosensors, like taste buds (D'Oh Cate beat me to it) at the tip
- Bugscope Teamthe actual piercing part is smaller and inside the sheath we see now
- Studentwhats that
Bugscope Teamum frass
- Studentwhats frass
- Bugscope Teamfrass is another term for insect poop
- Bugscope Teamdo you recognize this?
- Bugscope Teamof course you can read what it is above the window
- Bugscope Teamthis is the deadliest insect
- Bugscope Teamwith mosquitoes it is easier to tell the boys from the girls
- 5:22 pm
- Studentis that another isect on its nose
Bugscope Teamno that is if I see the same thing you're talking about, one of its palps and also its proboscis
- Studenthow do you tell
Bugscope Teamthe antennae of males are ornate, and those of females are not
- Bugscope Teamso many diseases spread
- Bugscope Teamthey both have a proboscis, but only the female uses hers to suck blood; males either don't eat at all or live on nectar
- Studentwhat is palp
Bugscope Teamthey help the insect to taste or move food around.
Bugscope Teamit's just a term to identify the elongated segments near the mouth parts.
- Bugscope Teamthis pillow like thing is a pedicel, the base of the antenna
- Studentwhats this
Bugscope Teamthose are the ommatidia -- the eye facets -- which are desiccated
- Bugscope Teamnot very exciting antenna -- female
- Bugscope Teamthe ommatidia are the units that compose the compound eye
- Studentis that hair
Bugscope Teamyes it is -- mostly chemosensory setae
- Bugscope Teamthis is the antenna, it's covered in setae that help increase surface area for chemosensing.
- Bugscope Team*setae = fancy term for hair in insects
- 5:27 pm
- Studentwhats that
Bugscope Teamthese are scales
- Bugscope Teamthey look like the end of a paddle
- Bugscope Teamscales are found on moths, butterflies, mosquitoes, silverfish, and very few other insects
- Studentwhich part has scales???
Bugscope Teamthis is on the thorax, but they are all over
- Bugscope Teamscales on wings have the effect of reducing friction.
- Bugscope Teaminsects have a head, a thorax, two antennae, six legs, and an abdomen
- Studentwhy do they have scales do they help them to move
Bugscope Teamyes, they help reduce the effects of friction
- Studentis that one scale we can see?
- Bugscope Teamthe hairs we see now are microsetae -- they are not sensory but likely help with thermoregulation and also recognition by other mosquitoes
- StudentWhats Friction mean
Bugscope Teamfriction is when things stick when the rub together rather than sliding easily off of each other
- Bugscope Teamit's the force resisting a motion along a surface
Bugscope TeamCate is a physicist and gets to use it, for a change.
- Bugscope Teamice skating has little friction, or when you play air hockey
- 5:32 pm
- Studenthow many scales cover the mosquito
Bugscope Teamprobably a few thousand
- Bugscope Teamscales come off very easily, and that is good when you are an insect that flies into a spider web
- Bugscope Teamhahaha
- Studentthats so ugly
Bugscope Teamyeah mosquitos aren't the prettiest kind of insect...
- Bugscope Teammoths can be kind of scary looking too
- StudentWhats that??????????????????
- Bugscope Teamunderside of filter w bacteria -- on the other side
- Studentvery interesting
- Bugscope Teamthis is like the rave scene in the 2nd Matrix movie
- Bugscope Teampartying bacteria
- Student what bacteria is that
Bugscope Teamthis is what e. coli looks like, but not sure if this is e. coli
- Bugscope Teamthese are not jellybeans you would want to eat haha
- Studentthese look like jellybeans what is that
Bugscope Teamhaha yeah that's it
- 5:37 pm
- Bugscope Teamthese are bacilli -- the rod-shaped bacteria
- Bugscope Teamthose are the bacteria, lot's of different kinds of bacteria are cylindrical like this though
- Bugscope Team*lots
- Bugscope Teamthere are three basic shapes of bacteria: rods, round dudes (the cocci), and spiral dudes (the spirochetes)
- Studentwhat the most magnified it can go
Bugscope Teamwhen we work with researchers and also go to a shorter working distance than we are using today, we can take useful, publishable images at 200,000x
- Studentwhats the fluff around it
Bugscope Teamprobably dust or environmental particles?
Bugscope Teamsome of it is the remnants of the biofilm some bacteria use to protect themselves; they swim in it
- Studentwhat are we looking at right now
Bugscope Teamlots of bacteria
- Studentis a tooth
- Bugscope Teamthese are bacteria sitting on a filter. The bacteria was immersed in a liquid and then someone pushed the liquid with the bacteria against the filter so that all that the liquid would pass through, but the bacteria would be caught on the filter
- Studenti was wrong
- Studentwhat is that
- Bugscope Teamnow we are looking at the surface of a starfish
- 5:43 pm
- Bugscope Teamit has these mouthlike elements all over it
- Bugscope Teamtotally creepy
- Bugscope Teamawesome
- Studentis this where it eats from
Bugscope Teamwe were going to ask you! we live far inland
- Bugscope Teamyou know what else is creepy? the fact that they eat with the stomachs everted
- Bugscope Team*everted = inside out
- Studentis it a hairy starfish
Bugscope Teamin this case, we are looking at crystals that precipitated on the surface when the starfish dried out
- Bugscope Teamand they have an eye at the end of each arm
- Studentwe have 5mins left
- Bugscope Teamtube foot
- Studentwhat is that??????????????
- Bugscope Teamthis is the meaning of the universe, inside the starfish's tube foot
- Studentok when ever something weird comes up tell me
- 5:48 pm
- Studentstink insect
Bugscope Teamcould be, because it seems to have the same kind of vent that larger stinkbugs have
- Bugscope Teamsomething comparable
- Studentwhat is that???????????????
Bugscope Teamsorry have never seen anything quite like this before
- Studenthow many insects do you have to magnify at this point?
Bugscope Teamwe have shown you most of what is on the stub today
- Bugscope Teamsorry i got distracted by hunger
- Studentwhy do stink bugs stink?
Bugscope Teamthey can excrete a liquid from a gland located on either side of the body
- Bugscope Teamwhat might i know?
Bugscope Teamwhat that strange network was on the ventral side of the junior stinkbug
- Bugscope Teamoh i have no idea what that was
- Studentis this a fly
Bugscope Teamthis is a leafhopper
- Studentcould you show us the glan?
Bugscope Teamthe gland is on the inside
- Bugscope Teamthis is another true bug
- Studentwhat is that????
Bugscope Teamthe compound eye of the leafhopper
- 5:53 pm
- Studentwhat do the hairs do
Bugscope Teamthey are almost always sensory in some way; for smell, touch, wind, hot/cold, proprioception...
- Studentis that its leg
Bugscope Teamyea the two things that look like elephant tusks are the tarsal claws at the end of the leg
- Studentwhat is proprioception...
- Bugscope Teamproprioception is self-sensing; often with insects we see bristles that help the insect sense when its limb is overextended, for example
- Studentis that a ant
Bugscope Teamyes! a lot of ants doing cannonballs
- Bugscope Teamalmost all ants we see are females
- Studentis that an eggsack
Bugscope Teamits the compound eye
- 5:59 pm
- Bugscope Teamall the workers that we see bustling about are females, males will usually have wings and are only good for mating when the colony grows and splits off
- Studentis anything eating or doing something to eachother
Bugscope Teamno the ants were cold and curled up; I need to find a better way to preserve them
- Bugscope Teamtime for me to shut down...
