- 10:32 am
- Bugscope Teamplease let us have control of the 'scope until we have the presets done
- Bugscope Teamoh Good morning!, sorry
- TeacherSorry, I was just checking things out before my class gets here.
- Bugscope Teamno probe,\\
- Bugscope Teamhaha cannot type -- this is Scott using Cate's login
- Bugscope Teamwe're a bit late setting up 'cause it took a while to pump down
- 10:37 am
- Teachermy students will not be here until 10:50
- Bugscope Teamcool we should be good
- Teachercan I have them all logged in individually or do you want us just as one group?
- Bugscope Teamthey can be logged in individually or two to a computer; we can handle up to 20 or so logins at once; then we might start to have lag
- Bugscope Teamfor us it is much more fun, and we think it is better for the students, if they get to chat individually
- 10:43 am
- 10:49 am
- Bugscope Teamkids can log in anytime of course
- 10:55 am
- Bugscope Teamhey good morning!
- Bugscope Teamwelcome to Bugscope!
- Bugscope Teamplease let us know when you have questions
- Bugscope Teamthis is a cute little borer
- Bugscope Teamsee its compound eyes?
Bugscope TeamHello Cake Face!
- Bugscope Teamwe can see its jaws (mandibles) as well, and its antennae
- StudentWow it's eyes are cool!
- StudentI am excited
- StudentMe to
- StudentThe mandibles are cool
- StudentI like bugs
- Bugscope Teamyour teacher can control the microscope now; she can change mag, focus, and also she can choose from among the presets and make the 'scope drive to a new one
- 11:00 am
- Bugscope Teamnow we can see one antenna, and we're centered on one of the compound eyes
- Bugscope Teamsee the facets of the compound eye?
- StudentThis is cool
- Bugscope TeamI'm driving from my desk, but your teacher can do this as well...
- StudentRight I knew that lol
- StudentThey have exoskeletons not bone
Bugscope TeamYes! The exoskeleton is much like a shell, or a suit or armor
- StudentThe jaws are awesome
- StudentHow many cells do they have
Bugscope Teamprobably thousands upon thousands
- StudentDoes it have hair
Bugscope Teamyes it has hair all over its body. when you see hair on insects, you call the hairs setae, because they aren't mammals. the hairs help them sense what is going on around it
- StudentWow a lot of cells!!!!
- StudentThat's cool
- StudentWow thAts awesome!
- Bugscope Teamso it has super sharp, fork-like mandibles that open like a gate
- StudentHow long have you been studing this subject?
- Bugscope Teamand below the mandibles are palps, which are accessory mouthparts
- StudentWhat part of the body is that
Bugscope Teamthis is a closeup of the face of a small beetle
- StudentWhat is your favorite insect?
Bugscope Teamsometimes weevils are my favorite
- 11:05 am
- StudentAre the long things antennae
Bugscope Teamwe cannot see them right now, but yes
- StudentI want to see another bug
- StudentWe are.
- StudentBe patient guys
- StudentHow do you know
- Bugscope Teamhere's a big wasp
- StudentAre the bugs gross to look at up close.
Bugscope TeamI think they look cool
- StudentThey use the hairs as sensors basically like a radar
- StudentCan we see the legs
Bugscope Teamthe best way to see the legs is to take the mag down as low as possible and then move south on the body -- or go to a preset that shows claws
- StudentWhat is the claw shaped thing in its mouth
Bugscope Teamthat is its mandibles
- StudentCan we see the abdomen
- StudentAre all the bugs going to be in black and white?
Bugscope Teamyes because we are using electrons to image and not light. sometimes you might see an electron image in color, but that was done artificially
- StudentAre the bugs cool.
- StudentWhat is your favorite bug to view
Bugscope TeamI like earwigs, too, because they often have mites living on them
- StudentAre those the teeth under the eyes?
Bugscope Teamsort of, they have similar function, but are called mandibles in insects
- StudentOk. Thanks
- StudentCan we see the abdomen of the wasp?
- StudentCan we see the body?
- StudentWhy do they need hair on their head
Bugscope Teambecause they do not have skin, they need to be able to sense things touching them anywhere, including on the head
- StudentDoes it have a small head
- Bugscope Teamthorax
- Bugscope Teamoh okay this is the head of the cranefly
- StudentWhy do bugs have mandibles
Bugscope Teamthey don't all have them, but for the ones that do, they use them to chew and also to carry things
- 11:10 am
- StudentAre those the antennae?
Bugscope Teamyes they are -- we can see that one is broken
- StudentWhy does it have tube like structures on its head
Bugscope Teamthose are the antennae
- Bugscope Teamsee the cranefly kind of has a hump back
- StudentDo all bugs have compound eyes?
Bugscope Teamnot all, but many
- Bugscope Teamsome flying insects, especially, also have three simple eyes on the top of their heads, called ocelli
- Studentcan it sting yoU?
Bugscope TeamThe crane fly? nope.
- StudentHow did the antennae get broken
Bugscope Teamafter insects die, they dry out and get brittle, which makes it easy to break off a limb or other body piece
- StudentDo they have n
- StudentWhy do insect's eyes look like nets
Bugscope Teamup close they look like multifaceted hexagonal arrays
- StudentDo crane flys live in swampy areas?
Bugscope Teamyes they do. they are often mistaken for giant mosquitos
- StudentDoes a broken antennae hurt the bug?
Bugscope Teammost likely not. insects don't feel pain the way that we do.
- StudentOh ok!
- StudentDo they have noses
- StudentYa why?
- StudentCan you zoom in on the eye
- StudentWhy does the mouth stick out
Bugscope Teamnot sure -- I am not sure how much they eat as adults
- StudentWhat's the flat surface behind the bug
Bugscope Teamthat's the surface that the insects are stuck on, it's a stick surface so they won't move while we look at them under the scope.
- StudentDo they stil sting after they die
Bugscope Teamcraneflies do not sting; was it something else you were referring to?
- StudentThat's creepy!
- StudentDoes this one have compound eyes then?
Bugscope Teamyes this grasshopper does
- StudentThanks scot!!
- StudentHow long have you been studying this topic?
Bugscope Teamwe have been doing bugscope since 1999
- StudentWhat's your favorite insect?
- StudentIs the grass hopers antenna broken
Bugscope Teamyes it is. almost fell off all the way
- StudentYeah I mean bees and wasps
Bugscope Teamthey don't sting after they die; the reason honeybees die when they sting us is that the barbs on their stingers get caught in our skin. uh -- so I take that back, in a way: once the stinger is in your skin, it has a little venom pump with it that keeps pumping venom into your skin
- StudentHow long does it take you to identify
- 11:15 am
- StudentAre those the legs at the bottom???
- StudentWhere is its mouth mandibles?
Bugscope Teamthey are near the top of the screen. the ant is looking up
- StudentDo they have feet
- StudentIs a kricket bigger than a grasshopper
Bugscope Teamjust depends on which kind of each; generally I think we could say that grasshoppers are bigger
- StudentWhy are the legs hairy?
- StudentCan you show the body more
- StudentWhat are the little antennae type thing called?
Bugscope Teamthe small things around the mouth are called palps
- Student I can actually tell it is an ant!
- StudentWhy does it have a long line down the middle of its head
Bugscope Teamits a kind of seam -- that's how it grew
- StudentOh cool!
- StudentDoes it have hair
Bugscope Teamyes tiny sensory setae that look to us like hair
- StudentThat's côôl
- StudentIt's abdomen
- StudentIt is cool to see a bug at this level
- StudentWhy does its eyes have bumps on them?
Bugscope Teamthe bumps are the individual lenses -- the facets of the eye. each facet and its extension into the eye is called an ommatidium
- StudentI have it is cool though.
- StudentIt's weird
- StudentCan we look at the abdomonen
Bugscope Teamin an ant, we now know from talking with the entomologists, the abdomen is called a 'gaster'
- StudentSo they have a million miniature eyes basically
Bugscope Teamthey can. usually ants have much less. flies or other flying insects would have much more
- StudentHow much weight can an ant carry?
Bugscope TeamThere are various estimates as to how much it can carry based on its body weight
- StudentCan that bite me
Bugscope Teamtheir claws are so small it would not hurt you
- StudentWhat are the rice shaped things in the background?
Bugscope Teamthose are scales on the beetle
- StudentIs it poisoners
- StudentOh! Thanks Cate!
- StudentWhy do the ants butt look
Bugscope Teamthe butt is the gaster, and it looks like a bunch of shells, or kind of like armor
- 11:21 am
- StudentIs that it's head
- StudentThat is awesome!!
- StudentWhat insect does the claw belong to?
Bugscope Teamit was a type of beetle. i wasn't sure what kind
- StudentThese are the spider eyes!!!
- StudentWhat spider is this
- StudentWhat are the things below the eyes?
- StudentAre the hairy things legs"
Bugscope Teami believe those are its fangs.
- StudentThey are the mouth
- StudentWhat are the bumps on its head
Bugscope Teamthose are the simple eyes that spiders have. they usually have 8
- StudentI'm pretty sure theses are the eyes
- StudentAre the bugs harmless
- StudentWhy does its eye look fuzzy
Bugscope Teamits face is covered in hairs, so from this angle, the eyes do look fuzzy
- StudentWhat are those round furry things
Bugscope Teamthe round things are its eyes
- StudentI can see the setae!
- StudentSo much setae
- StudentIs that hair on it
- StudentWhat is the hair on the eye called
Bugscope Teamwith spiders, the hair near the eye is often called plumose setae, and its because they look like long Christmas trees\
- StudentThe setae is all over its body
- StudentWhat Are the two big barrel shaped structures
- StudentIs there a bug in it
- StudentIs this spider poised
Bugscope Teamspiders aren't poisonous. they are venomous though. and i'm sure this one was, but not so bad for us
- StudentHow many eyes does a spider have
Bugscope Team0-8 depending on species
Bugscope Teammostly only the even numbers if i remeber correctly
- StudentI see the mandibles
Bugscope Teamthe great big long things that function like mandibles hold the fangs at the lower end, and in spiders as well as some other arthropods they are called chelicers or chelicerae
- StudentHow do they make there webs
- StudentSpider webs are beautiful
- StudentWhat the seintific name for the spider web
- StudentThat looks disgustingly cool!
- StudentWhat's the difference between poison and venom?
- StudentOh that's cool, Scot!!
- StudentCool ;)
- StudentSpider webs look a lot more confusing up close
- 11:26 am
- StudentDo you just identify bugs?
Bugscope TeamJoe is an entomologist, so he is good at it, but Cate and I train students to use microscopes and run Bugscope secondarily -- we are not good at identification
- StudentWhat is the difference between poision and venom
Bugscope Teampoisonous can happen when you ingest something- like a mushroom can be poisonous. Venomous comes from stinging or biting. it is injected into the prey
- StudentThank you for answering us
- StudentCan we see the body
- StudentHow do they make a perfect web
Bugscope Teamthey must have some kind of algorithm in their brain that they follow; they know how to do it sort of automatically
- StudentWhy are spider webs sticky?
- StudentHow does it get on the seed
- StudentIt is spiky so it sticks
- StudentAre the scales like on fish
- StudentHow do they make there webs?
Bugscope Teamthe web comes from their spinnerettes, which are at the tip of the abdomen, and it is liquid when it is inside the spider that becomes silk and hardens when it leaves the spider, when it is exposed to air
Bugscope Teamsome of the web is sticky, and some is not; they can choose which to make
- StudentCan we see the mandibles
Bugscope Teamyou can kind of see them, between the palps and the antennae, if you look layer-wise, the mandibles are there but it's not very obvious
- StudentDo you think beetles are gross?
Bugscope Teammostly not too gross; they have to do what they do to live\
- StudentCan the microscope you are using zoom in farther or is that the max???????
- StudentWould they be able to see something if it was standing right in front of it.because it's eyes are far out.
- StudentWhy are there scales?
- 11:32 am
- StudentWhy is it spiky ?
Bugscope Teamyea, sometimes they will stick to different pollinators. some pollen are not spikey, and some have wings
- StudentWhat is ant comb
Bugscope Teamthey use this appendage to help any dirt they might have off their antennae
- StudentWhy does it have scales
Bugscope Teamthere are a variety of reasons: one is that they reflect light in a way that makes them identifiable to their own species. scales in insects that have them also protect them from spiderwebs by falling off and sticking to the web, allowing the insect to slip away
- StudentCan you zoom in farther??
- StudentWhere on the ant is it located
Bugscope Teamthis is on one of the joints of the forelimb, kind of like an elbow
- StudentHow much do beetles weigh
Bugscope Teamit depends on the size, of course, from far less than a gram to many grams
- StudentSo it's a fuzzy elbow
- StudentWhy dose ants need combs
Bugscope Teamthe combs help them clean their antennae so they can smell and sense better
- StudentIs it feathers
Bugscope Teamthey're tiny setae
- StudentWhat's the thing that looks fuzzy
Bugscope Teamsorry, missed it
- StudentWhy does it look like a bird's wing??
- StudentIs that hair on it
- StudentWhy do bugs eat each other?????
- StudentWhat is that
- StudentIt's really cool that you have been studying for almost 14 years!
- StudentHow come there are red ants and black ants. What's the difference?
Bugscope Teamthey probably get their colors from what they eat and how it is metabolized, and we don't know but they may help them identify each other, although that is mostly done chemically, through pheromones -- through chemical scents
- StudentThat looks just like hair
- StudentDo you like your job
Bugscope Teamit is often really fun
- StudentWhy do they have combs
Bugscope Teamthey rely on their antennae for most of their information, so they have to keep them clean of dirt with the combs to do this
- 11:37 am
- StudentIt looks like a forest
- StudentWhat does setae do?
Bugscope Teamthey are sensitive to various things in the environment, and different ones are sensitive in different ways, of course; some are very sensitive to vibration, which is what sound is; some are sensitive to hot/cold; some are sensitive to touch or wind
- StudentWhat is that?
- StudentIs that it's head or it's thorax
Bugscope Teamthose were on a claw, which is also one of the tarsi, which are the last 5 or so segments of the leg
- StudentWhat is a arolium
- StudentWhat is a tarsus
- StudentWhere is the tarsus and arolium located?
Bugscope Teamat the end of each leag
- StudentWhat do aroliums do
Bugscope Teamthey can be puffed up or shrunken, and they can thus be used to help hold onto things by inflated between them
- StudentWhat is the weak link in the bugs body
Bugscope Teamit depends on which insect -- with some insects it is the neck
- StudentSo are they kinda like toes?
Bugscope Teamyes they are!
- StudentAre those it's legs?
Bugscope Teamyes. mostly
- StudentWhat are those little spikes
Bugscope Teamthe claws...
- StudentIsn't the neck where the life artery is?
Bugscope Teamwell it is pretty important, yes
- StudentIs using a bug scope hard
Bugscope Teamno -- you would be good at it, really
- Bugscope Teamto the top we see palps, which have lots of joints
- StudentWhat are the two things on top of the leg:)
Bugscope Teamcan you describe them better, sorry...
- 11:42 am
- Bugscope TeamThank you, Everyone!
- Bugscope TeamWe enjoyed working with you all.
- StudentThank you.
Bugscope TeamThank you, Maylee!
