- Bugscope Team sample is pumping down
- Bugscope Team now we're making presets
- Student morning scott
- Bugscope Team hello!
- Bugscope Team welcome to Bugscope!
- Student things are working well here
Bugscope Team sweet!
- Bugscope Team Year6 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.
- Student kids are starting to arrive here slowly but surely
Bugscope Team awesome
- Bugscope Team stinger does not look good, sorry
- Student looks good to us
- Bugscope Team Cate wrote 'headless wasp' on her drawing...
- Student hello its alyssa and chealsea and indi
Bugscope Team hello! Welcome to Bugscope!
- Student is that the head of a spider
Bugscope Team yes it is!
- Bugscope Team I think there are enough presets. Kind of a strange selection today.
- Bugscope Team so we are ready to roll
- Student thats realy cool how u can get real close to something
Bugscope Team we are so lucky to have equipment like this to play around with
- Student is that hair
Bugscope Team yes, in insects and similar arthropods we're s'posed to call hair setae, bristles, spines, trichae, microsetae, etc. but yes it's hair
- Student can we zoom in
Bugscope Team yes if you wish
- Bugscope Team year6 you actually have control of the 'scope and should be able to change mag, select from the presets, etc.
- Student thanks
- Bugscope Team if 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 Team please let me know if for some reason it doesn't work
- Bugscope Team I can drive if necessary
- Student its not working you drive
- Bugscope Team spiders have lots of sensory setae, often to help them sense vibration
- Student what r those 3 little holes?
Bugscope Team haha I am not sure -- we are so close; they may help pick up chemical scents
- Bugscope Team hello
- Bugscope Team now you can see that same seta, right in the middle of the eyes
- Bugscope Team Hi Cate!
- Bugscope Team Cate can you see this?
- Student hi Cate......
- Student yes
- Student whats that?
Bugscope Team this 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 Team now you can see its eight eyes
- Bugscope Team the two things in front, curved downward, are the chelicers, or chelicerae
- Student thats interesting
- Bugscope Team the chelicerae hold the fangs, which curve inward toward each other
- Student are they the fangs
Bugscope Team I just went looking for the fangs but could not see them
- Bugscope Team the chelicerae in spiders are hollow, and house a venom gland
- Student it is really hairy
- Bugscope Team okay I am on another confuser now
- Student whats that
Bugscope Team this is an aphid
- Bugscope Team aphids are true bugs -- Hemiptera
- Bugscope Team ladybugs like to eat these pests
- Bugscope Team they have piercing/sucking mouthparts
- Student they look so weird
- Bugscope Team they have piercing sucking mouth parts, which the use to feed on plants
- Bugscope Team sometimes ants are nice to them, in a way, and treat them like cattle
- Bugscope Team they kind of look like weird rabbits with their antenna-ears
- Student zoom in on the sucking mouth part please
- Bugscope Team see the compound eyes on either side of the head?
- Bugscope Team the ants eat the excretion of the aphids, also called honeydew
- Bugscope Team some ants will aggressively protect them
- Student what do you mean they treat them like cattle
Bugscope Team they kind of farm them and feed on the honeydew, like Jose said
- Student can you please zoom in on the mouth
- Bugscope Team like a rancher protecting cows from coyotes
- Bugscope Team this is it, the mouthpart
- Bugscope Team but some aphids, instead of secreting honeydew from their cornicles, secrete this stuff that's like hotmelt glue
- Bugscope Team the proboscis is in the top half, right down the middle
- Bugscope Team yes sorry it has a limb crossing in front of the tip
- Bugscope Team there is a leg in the way of seeing it really well i think
- Student how do the ants aggressively protect them
Bugscope Team they keep other ants and ladybugs from feeding on them
- Bugscope Team I 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.
- Student yes please
- Student can you tell if it is male or female
Bugscope Team sometimes you cannot tell unless you dissect them
- Student what on earth is that
- Student what are these?\
Bugscope Team so this is another aphid. we are looking at the ventral side, and this is the tip of the proboscis
- Bugscope Team these are probably special hairs that help it taste
- Bugscope Team it has chemosensors, like taste buds (D'Oh Cate beat me to it) at the tip
- Bugscope Team the actual piercing part is smaller and inside the sheath we see now
- Student whats that
Bugscope Team um frass
- Student whats frass
- Bugscope Team frass is another term for insect poop
Bugscope Team exactically
- Bugscope Team do you recognize this?
- Bugscope Team of course you can read what it is above the window
- Bugscope Team this is the deadliest insect
- Bugscope Team with mosquitoes it is easier to tell the boys from the girls
- Student is that another isect on its nose
Bugscope Team no that is if I see the same thing you're talking about, one of its palps and also its proboscis
- Student how do you tell
Bugscope Team the antennae of males are ornate, and those of females are not
- Bugscope Team so many diseases spread
- Bugscope Team they both have a proboscis, but only the female uses hers to suck blood; males either don't eat at all or live on nectar
- Student what is palp
Bugscope Team they help the insect to taste or move food around.
Bugscope Team it's just a term to identify the elongated segments near the mouth parts.
- Bugscope Team this pillow like thing is a pedicel, the base of the antenna
- Student whats this
Bugscope Team those are the ommatidia -- the eye facets -- which are desiccated
- Bugscope Team not very exciting antenna -- female
- Bugscope Team the ommatidia are the units that compose the compound eye
- Student is that hair
Bugscope Team yes it is -- mostly chemosensory setae
- Bugscope Team this is the antenna, it's covered in setae that help increase surface area for chemosensing.
- Bugscope Team *setae = fancy term for hair in insects
- Student whats that
Bugscope Team these are scales
- Bugscope Team they look like the end of a paddle
- Bugscope Team scales are found on moths, butterflies, mosquitoes, silverfish, and very few other insects
- Student oh
- Student which part has scales???
Bugscope Team this is on the thorax, but they are all over
- Bugscope Team scales on wings have the effect of reducing friction.
- Bugscope Team insects have a head, a thorax, two antennae, six legs, and an abdomen
- Student why do they have scales do they help them to move
Bugscope Team yes, they help reduce the effects of friction
- Student is that one scale we can see?
- Bugscope Team the hairs we see now are microsetae -- they are not sensory but likely help with thermoregulation and also recognition by other mosquitoes
- Student Whats Friction mean
Bugscope Team friction is when things stick when the rub together rather than sliding easily off of each other
- Bugscope Team it's the force resisting a motion along a surface
Bugscope Team Cate is a physicist and gets to use it, for a change.
- Bugscope Team ice skating has little friction, or when you play air hockey
- Student how many scales cover the mosquito
Bugscope Team probably a few thousand
- Bugscope Team scales come off very easily, and that is good when you are an insect that flies into a spider web
- Bugscope Team hahaha
- Student thats so ugly
Bugscope Team yeah mosquitos aren't the prettiest kind of insect...
- Bugscope Team moths can be kind of scary looking too
- Student Whats that??????????????????
- Bugscope Team underside of filter w bacteria -- on the other side
- Student very interesting
- Bugscope Team this is like the rave scene in the 2nd Matrix movie
- Bugscope Team partying bacteria
- Student what bacteria is that
Bugscope Team this is what e. coli looks like, but not sure if this is e. coli
- Bugscope Team these are not jellybeans you would want to eat haha
- Student these look like jellybeans what is that
Bugscope Team haha yeah that's it
- Bugscope Team these are bacilli -- the rod-shaped bacteria
- Bugscope Team those are the bacteria, lot's of different kinds of bacteria are cylindrical like this though
- Bugscope Team *lots
- Bugscope Team there are three basic shapes of bacteria: rods, round dudes (the cocci), and spiral dudes (the spirochetes)
- Student what the most magnified it can go
Bugscope Team when 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
- Student whats the fluff around it
Bugscope Team probably dust or environmental particles?
Bugscope Team some of it is the remnants of the biofilm some bacteria use to protect themselves; they swim in it
- Student what are we looking at right now
Bugscope Team lots of bacteria
- Student is a tooth
- Bugscope Team these 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
- Student i was wrong
- Student what is that
- Bugscope Team now we are looking at the surface of a starfish
- Bugscope Team it has these mouthlike elements all over it
- Bugscope Team totally creepy
- Bugscope Team awesome
- Student is this where it eats from
Bugscope Team we were going to ask you! we live far inland
- Bugscope Team you know what else is creepy? the fact that they eat with the stomachs everted
- Bugscope Team *everted = inside out
- Student is it a hairy starfish
Bugscope Team in this case, we are looking at crystals that precipitated on the surface when the starfish dried out
- Bugscope Team and they have an eye at the end of each arm
- Student we have 5mins left
Bugscope Team no!
- Bugscope Team tube foot
- Student what is that??????????????
- Bugscope Team this is the meaning of the universe, inside the starfish's tube foot
- Student ok when ever something weird comes up tell me
Bugscope Team haha
- Student stink insect
Bugscope Team could be, because it seems to have the same kind of vent that larger stinkbugs have
- Bugscope Team something comparable
- Student what is that???????????????
Bugscope Team sorry have never seen anything quite like this before
- Student oh
- Student how many insects do you have to magnify at this point?
Bugscope Team we have shown you most of what is on the stub today
- Student wow
- Bugscope Team sorry i got distracted by hunger
- Student why do stink bugs stink?
Bugscope Team they can excrete a liquid from a gland located on either side of the body
- Bugscope Team what might i know?
Bugscope Team what that strange network was on the ventral side of the junior stinkbug
- Bugscope Team oh i have no idea what that was
- Student is this a fly
Bugscope Team this is a leafhopper
- Student could you show us the glan?
Bugscope Team the gland is on the inside
- Bugscope Team this is another true bug
- Student what is that????
Bugscope Team the compound eye of the leafhopper
- Student cool
- Student what do the hairs do
Bugscope Team they are almost always sensory in some way; for smell, touch, wind, hot/cold, proprioception...
- Student is that its leg
Bugscope Team yea the two things that look like elephant tusks are the tarsal claws at the end of the leg
- Student what is proprioception...
- Bugscope Team proprioception is self-sensing; often with insects we see bristles that help the insect sense when its limb is overextended, for example
- Student is that a ant
Bugscope Team yes! a lot of ants doing cannonballs
- Bugscope Team almost all ants we see are females
- Student is that an eggsack
Bugscope Team its the compound eye
- Bugscope Team all 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
- Student is anything eating or doing something to eachother
Bugscope Team no the ants were cold and curled up; I need to find a better way to preserve them
- Bugscope Team time for me to shut down...
