- Bugscope Team please let us have control of the 'scope until we have the presets done
- Bugscope Team oh Good morning!, sorry
- Teacher Sorry, I was just checking things out before my class gets here.
- Bugscope Team no probe,\\
- Bugscope Team haha cannot type -- this is Scott using Cate's login
- Bugscope Team we're a bit late setting up 'cause it took a while to pump down
- Teacher my students will not be here until 10:50
- Bugscope Team cool we should be good
- Teacher can I have them all logged in individually or do you want us just as one group?
- Bugscope Team they 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 Team for us it is much more fun, and we think it is better for the students, if they get to chat individually
- Teacher great!
- Bugscope Team kids can log in anytime of course
- Bugscope Team hey good morning!
- Bugscope Team welcome to Bugscope!
- Bugscope Team please let us know when you have questions
- Student Ok
- Student Hi
Bugscope Team Hi!
- Bugscope Team this is a cute little borer
- Student Hi!!!!
- Bugscope Team see its compound eyes?
- Student Hello
Bugscope Team Hello Cake Face!
- Student Ok
- Bugscope Team we can see its jaws (mandibles) as well, and its antennae
- Student Wow it's eyes are cool!
- Student I am excited
Bugscope Team sweet
- Student Me to
- Student The mandibles are cool
- Student I like bugs
- Bugscope Team your 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
- Bugscope Team now we can see one antenna, and we're centered on one of the compound eyes
- Bugscope Team see the facets of the compound eye?
- Student Yep
- Student This is cool
- Bugscope Team I'm driving from my desk, but your teacher can do this as well...
- Student Right I knew that lol
- Student They have exoskeletons not bone
Bugscope Team Yes! The exoskeleton is much like a shell, or a suit or armor
- Student The jaws are awesome
- Student How many cells do they have
Bugscope Team probably thousands upon thousands
- Student Does it have hair
Bugscope Team yes 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
- Student Wow a lot of cells!!!!
- Student It's
- Student That's cool
- Student Wow thAts awesome!
- Bugscope Team so it has super sharp, fork-like mandibles that open like a gate
- Student Ikr
- Student How long have you been studing this subject?
- Bugscope Team and below the mandibles are palps, which are accessory mouthparts
- Student What part of the body is that
Bugscope Team this is a closeup of the face of a small beetle
- Student What is your favorite insect?
Bugscope Team sometimes weevils are my favorite
- Student Are the long things antennae
Bugscope Team we cannot see them right now, but yes
- Student I want to see another bug
- Student We are.
- Student Be patient guys
- Student How do you know
- Student Ok
- Bugscope Team here's a big wasp
- Student Are the bugs gross to look at up close.
Bugscope Team I think they look cool
- Student Wow
- Student They use the hairs as sensors basically like a radar
- Student Can we see the legs
Bugscope Team the 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
- Student What is the claw shaped thing in its mouth
Bugscope Team that is its mandibles
- Student Can we see the abdomen
- Student Are all the bugs going to be in black and white?
Bugscope Team yes because we are using electrons to image and not light. sometimes you might see an electron image in color, but that was done artificially
- Student Are the bugs cool.
- Student What is your favorite bug to view
Bugscope Team I like earwigs, too, because they often have mites living on them
- Student Are those the teeth under the eyes?
Bugscope Team sort of, they have similar function, but are called mandibles in insects
- Student Ok. Thanks
- Student Can we see the abdomen of the wasp?
- Student Can we see the body?
- Student Why do they need hair on their head
Bugscope Team because they do not have skin, they need to be able to sense things touching them anywhere, including on the head
- Student Does it have a small head
- Bugscope Team thorax
- Bugscope Team oh okay this is the head of the cranefly
- Student Creepy!!:)
- Student Why do bugs have mandibles
Bugscope Team they don't all have them, but for the ones that do, they use them to chew and also to carry things
- Student Yum
- Student Are those the antennae?
Bugscope Team yes they are -- we can see that one is broken
- Student Why does it have tube like structures on its head
Bugscope Team those are the antennae
- Bugscope Team see the cranefly kind of has a hump back
- Student Do all bugs have compound eyes?
Bugscope Team not all, but many
- Bugscope Team some flying insects, especially, also have three simple eyes on the top of their heads, called ocelli
- Student can it sting yoU?
Bugscope Team The crane fly? nope.
- Student Ok
- Student How did the antennae get broken
Bugscope Team after insects die, they dry out and get brittle, which makes it easy to break off a limb or other body piece
- Student Do they have n
- Student Why do insect's eyes look like nets
Bugscope Team up close they look like multifaceted hexagonal arrays
- Student Do crane flys live in swampy areas?
Bugscope Team yes they do. they are often mistaken for giant mosquitos
- Student Does a broken antennae hurt the bug?
Bugscope Team most likely not. insects don't feel pain the way that we do.
- Student Oh ok!
- Student Do they have noses
- Student Ya why?
- Student Can you zoom in on the eye
- Student Why does the mouth stick out
Bugscope Team not sure -- I am not sure how much they eat as adults
- Student Please
- Student What's the flat surface behind the bug
Bugscope Team that'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.
- Student Do they stil sting after they die
Bugscope Team craneflies do not sting; was it something else you were referring to?
- Student That's creepy!
- Student Does this one have compound eyes then?
Bugscope Team yes this grasshopper does
- Student Oh,cool
- Student Thanks scot!!
- Student How long have you been studying this topic?
Bugscope Team we have been doing bugscope since 1999
- Student What's your favorite insect?
- Student Wow!
- Student Is the grass hopers antenna broken
Bugscope Team yes it is. almost fell off all the way
- Student Yeah I mean bees and wasps
Bugscope Team they 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
- Student How long does it take you to identify
- Student Wow!
- Student Are those the legs at the bottom???
- Student Where is its mouth mandibles?
Bugscope Team they are near the top of the screen. the ant is looking up
- Student Do they have feet
- Student Is a kricket bigger than a grasshopper
Bugscope Team just depends on which kind of each; generally I think we could say that grasshoppers are bigger
- Student Why are the legs hairy?
- Student Can you show the body more
- Student What are the little antennae type thing called?
Bugscope Team the small things around the mouth are called palps
- Student I can actually tell it is an ant!
Bugscope Team sweet
- Student Why does it have a long line down the middle of its head
Bugscope Team its a kind of seam -- that's how it grew
- Student Oh cool!
- Student Does it have hair
Bugscope Team yes tiny sensory setae that look to us like hair
- Student That's côôl
- Student Yes
- Student Ew!!:)
- Student It's abdomen
- Student It is cool to see a bug at this level
- Student Ew!
- Student Why does its eyes have bumps on them?
Bugscope Team the bumps are the individual lenses -- the facets of the eye. each facet and its extension into the eye is called an ommatidium
- Student I have it is cool though.
- Student It's weird
- Student Can we look at the abdomonen
Bugscope Team in an ant, we now know from talking with the entomologists, the abdomen is called a 'gaster'
- Student So they have a million miniature eyes basically
Bugscope Team they can. usually ants have much less. flies or other flying insects would have much more
- Student How much weight can an ant carry?
Bugscope Team There are various estimates as to how much it can carry based on its body weight
- Student Can that bite me
Bugscope Team their claws are so small it would not hurt you
- Student What are the rice shaped things in the background?
Bugscope Team those are scales on the beetle
- Student Is it poisoners
Bugscope Team no
- Student Cool
- Student Oh! Thanks Cate!
- Student Why do the ants butt look
Bugscope Team the butt is the gaster, and it looks like a bunch of shells, or kind of like armor
- Student Is that it's head
- Student That is awesome!!
- Student What insect does the claw belong to?
Bugscope Team it was a type of beetle. i wasn't sure what kind
- Student These are the spider eyes!!!
- Student What spider is this
- Student What are the things below the eyes?
- Student Are the hairy things legs"
Bugscope Team i believe those are its fangs.
- Student They are the mouth
- Student What are the bumps on its head
Bugscope Team those are the simple eyes that spiders have. they usually have 8
- Student I'm pretty sure theses are the eyes
- Student Are the bugs harmless
- Student Why does its eye look fuzzy
Bugscope Team its face is covered in hairs, so from this angle, the eyes do look fuzzy
- Student What are those round furry things
Bugscope Team the round things are its eyes
- Student Ok!
- Student I can see the setae!
Bugscope Team yay!
- Student So much setae
- Student Is that hair on it
- Student What is the hair on the eye called
Bugscope Team with spiders, the hair near the eye is often called plumose setae, and its because they look like long Christmas trees\
- Student Poisonous
- Student The setae is all over its body
- Student What Are the two big barrel shaped structures
- Student Is there a bug in it
- Student Cool!
- Student Is this spider poised
Bugscope Team spiders aren't poisonous. they are venomous though. and i'm sure this one was, but not so bad for us
- Student How many eyes does a spider have
Bugscope Team 0-8 depending on species
Bugscope Team mostly only the even numbers if i remeber correctly
- Student I see the mandibles
Bugscope Team the 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
- Student How do they make there webs
- Student Spider webs are beautiful
Bugscope Team yes!
- Student What the seintific name for the spider web
- Student That looks disgustingly cool!
Bugscope Team haha
- Student What's the difference between poison and venom?
- Student Oh that's cool, Scot!!
- Student Cool ;)
- Student Spider webs look a lot more confusing up close
- Student Do you just identify bugs?
Bugscope Team Joe 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
- Student What is the difference between poision and venom
Bugscope Team poisonous can happen when you ingest something- like a mushroom can be poisonous. Venomous comes from stinging or biting. it is injected into the prey
- Student Thank you for answering us
- Student Can we see the body
- Student How do they make a perfect web
Bugscope Team they must have some kind of algorithm in their brain that they follow; they know how to do it sort of automatically
- Student Why are spider webs sticky?
- Student How does it get on the seed
- Student It is spiky so it sticks
- Student Are the scales like on fish
- Student How do they make there webs?
Bugscope Team the 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 Team some of the web is sticky, and some is not; they can choose which to make
- Student No
- Student Can we see the mandibles
Bugscope Team you 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
- Student Do you think beetles are gross?
Bugscope Team mostly not too gross; they have to do what they do to live\
- Student Awesome!!
- Student Can the microscope you are using zoom in farther or is that the max???????
- Student Would they be able to see something if it was standing right in front of it.because it's eyes are far out.
- Student Why are there scales?
- Student Why is it spiky ?
Bugscope Team yea, sometimes they will stick to different pollinators. some pollen are not spikey, and some have wings
- Student What is ant comb
Bugscope Team they use this appendage to help any dirt they might have off their antennae
- Student Why does it have scales
Bugscope Team there 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
- Student Can you zoom in farther??
- Student Where on the ant is it located
Bugscope Team this is on one of the joints of the forelimb, kind of like an elbow
- Student Cool!!:)
- Student How much do beetles weigh
Bugscope Team it depends on the size, of course, from far less than a gram to many grams
- Student So it's a fuzzy elbow
- Student Why dose ants need combs
Bugscope Team the combs help them clean their antennae so they can smell and sense better
- Student Is it feathers
Bugscope Team they're tiny setae
- Student What's the thing that looks fuzzy
Bugscope Team sorry, missed it
- Student Why does it look like a bird's wing??
- Student Is that hair on it
- Student Wow
- Student Why do bugs eat each other?????
- Student What is that
- Student It's really cool that you have been studying for almost 14 years!
- Student How come there are red ants and black ants. What's the difference?
Bugscope Team they 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
- Student That looks just like hair
- Student Do you like your job
Bugscope Team it is often really fun
- Student Why do they have combs
Bugscope Team they rely on their antennae for most of their information, so they have to keep them clean of dirt with the combs to do this
- Student It looks like a forest
- Student What does setae do?
Bugscope Team they 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
- Student What is that?
- Student Is that it's head or it's thorax
Bugscope Team those were on a claw, which is also one of the tarsi, which are the last 5 or so segments of the leg
- Student What is a arolium
- Student What is a tarsus
- Student Where is the tarsus and arolium located?
Bugscope Team at the end of each leag
Bugscope Team leg*
- Student What do aroliums do
Bugscope Team they can be puffed up or shrunken, and they can thus be used to help hold onto things by inflated between them
- Student What is the weak link in the bugs body
Bugscope Team it depends on which insect -- with some insects it is the neck
- Student So are they kinda like toes?
Bugscope Team yes they are!
- Student Are those it's legs?
Bugscope Team yes. mostly
- Student What are those little spikes
Bugscope Team the claws...
- Student Isn't the neck where the life artery is?
Bugscope Team well it is pretty important, yes
- Student Is using a bug scope hard
Bugscope Team no -- you would be good at it, really
- Bugscope Team to the top we see palps, which have lots of joints
- Student What are the two things on top of the leg:)
Bugscope Team can you describe them better, sorry...
- Student Bye
