- Bugscope Team microscope is pumping down
- Bugscope Team it's taking its time
- Bugscope Team close, now
- Bugscope Team we are making presets, almost done!
- Teacher hey
- Bugscope Team good morning!
- Bugscope Team Welcome to Bugscope!
- Teacher Thanks!
- Bugscope Team I'm looking for good diatoms on the waterbug's cuticle.
- Teacher cool
- Bugscope Team But we are ready to roll at any time.
- Teacher ok
- Teacher we are just waiting for the students to come
- Bugscope Team these are mites or crustaceans we have never seen before
- Teacher That is really cool!
- Teacher woah! what is that?
- Bugscope Team you can see that the diatoms are sometimes, like this one, covered with a lot of juju
- Teacher wow!
- Teacher giant mouth! lol
- Student where are we on this bug?
Bugscope Team now you can see its proboscis
- Bugscope Team if this dude bit you it would hurt
- Bugscope Team this is the head. it is so big we cannot see all of it at once
- Teacher I dont want to mess with that bug! I dont want to get bitten!
- Bugscope Team the eyes -- the compound eyes -- are on either side
- Student a nickname for him is the eastern toe biter.
Bugscope Team haha Perfect!
- Teacher what is the tube on top of the proboscis?
Bugscope Team we see that on true bugs, and I'm pretty sure it's part of the suction mechanism for slurping up liquid food
- Bugscope Team well it's taking forever for the reply from SEM to go through
- Student good morning!
Bugscope Team good morning!
- Bugscope Team okay who will be driving today? RMS?
- Teacher yeah
- Teacher we are all here. lets get started!
- Teacher cool
- Bugscope Team true bugs, which have piercing/sucking mouthparts -- such as cicadas, stinkbugs, etc. -- have them
- Bugscope Team spider eyes
- Bugscope Team you can see lots of setae -- hairs -- among the eyes
- Bugscope Team spider eyes are often not that sensitive, although some can see quite well
- Bugscope Team they do have very sensitive setae
- Student are their larger eyes more powerful?
- Student do you know why they have so many eyes?
- Student how are the eyes attached? it looks like they come right out from its body
Bugscope Team they are little domes that extend over the cephalothorax
- Bugscope Team cephalo- is the head, and thorax is the body part to which the legs are attached
- Bugscope Team insects have a separate head and thorax but spiders do not
- Teacher why do some of the hairs look "spiky" on the sides?
Bugscope Team they are 'plumose' setae, like little evergreen trees, very sensitive to vibration
- Bugscope Team some spiders have, as well, what are called 'urticating hairs'
- Teacher the hair on the left looks like a tree/bamboo! lol
Bugscope Team sure does!
- Bugscope Team the word 'urticaria' means 'itching'
- Bugscope Team a spider like a tarantula, for example, may release urticating hairs to dissuade a dog from bothering it, as the hairs go up its nose
- Teacher is there like a hole on the center of the hair?
Bugscope Team it's a place where the dried film we see is not there
- Teacher oh
- Bugscope Team there is some kind of liquid on the spider here -- a dried liquid
- Bugscope Team same with the enormous Eastern toe biter
- Student so in other words thats the acyual hair?
Bugscope Team this is a single plumose (referring to the smaller 'branches') seta
- Student *actual
- Bugscope Team I keep calling hairs setae because we're supposed to, but even entomologists give up and call them hair
- Bugscope Team here we get an idea that this is live imaging, because you can see that the preset moved from its original position, as shown in the thumbnail image
- Teacher our internet just went down.
- Teacher sorry
Bugscope Team looks like you are back!
- Teacher yeah
- Teacher just got it back up
- Bugscope Team Sweet!
- Bugscope Team Yay!
- Bugscope Team some web is sticky, and some is not. hard to tell here, though, isn't it?
- Bugscope Team if a spider got stuck in its own web it could eat its way out; they do recycle their web by eating it sometimes
- Student you can see the fractures
Bugscope Team cool!
- Teacher yummy spiderwebs!
Bugscope Team haha
- Teacher woops
- Bugscope Team it's good you're not a spider; they are kind of nasty critters
- Teacher haha
- Bugscope Team they inject venom into their prey, and the venom dissolves the internal organs, and then they suck it all up like a milkshake
- Bugscope Team actually ambush bugs and assassin bugs do the same thing
- Teacher haha
- Student id be a faster typer if i where a spider
Bugscope Team haha yeah
- Student are those true bugs?
Bugscope Team yes they are!
- Teacher what are the bumps on the right string?
Bugscope Team looks like some dried salts, perhaps, or just debris
- Bugscope Team be sure to cruise to some of the other presets!
- Teacher yummy salt... can I put some on my food?
- Bugscope Team it would be a pretty small amount. You wouldn't even notice it :)
- Teacher aw
- Bugscope Team this is live imaging of dead specimens in a vacuum chamber, and we are using electrons to collect the images
- Bugscope Team Cate is writing a better response...
- Teacher what is the hole-like thing on in the center of the screen currently?
- Bugscope Team the only liquid left is dried onto the cuticles of the specimenas
- Bugscope Team specimens...
- Teacher is it a cave?
Bugscope Team it is a place just below that spine in which there was a bubble of some sort
- Student where is the cuticle?
Bugscope Team if we take the mag down a bit we can see it better
- Bugscope Team the dimpled part is cuticle
- Bugscope Team insects do not have skin -- instead they have an exoskeleton, which is like a shell or a coat of armor
- Teacher what does the cuticle do?
Bugscope Team it protects the insect from the environment and also gives it support, since there is no endoskeleton
- Student so the cuticle is another phrase for exoskeleton?
Bugscope Team yes, sorry
Bugscope Team yes
- Bugscope Team now we see another example of cuticle, which is made of chitin
- Bugscope Team chitin is a material sort of like our fingernails
- Bugscope Team this is a spiracle, which is what insects breathe through
- Bugscope Team they have spiracles on either side of each body segment, and they help bring oxygen to the internal organs
- Bugscope Team on the inside, they are connected to tubes called tracheae
- Teacher what is the hole in the ant spiracle?
Bugscope Team that is the pore through which the insect breathes, or you could say regulates its respiration, since it can also close the spiracle
- Teacher cool
- Student the defenition of spiracle is?
Bugscope Team openings on the exoskeleton that lead to the respiratory system
- Teacher woah!
- Teacher is there anything inside the hole?
Bugscope Team yes there are often hairs in there that are kind of like nose hairs. They keep out particles
- Student yes there is somthing in the hole.
- Teacher what are those hairs?
Bugscope Team oops Cate just explained it... those serve as a filter to keep particles like pollen out of the tracheae
- Teacher asked too soon... lol
- Student so spiracles are kind of like gills?
Bugscope Team yes they are similar in function
- Student ok, neato!
- Teacher so THAT was the bug that we were wondering about!
- Bugscope Team here we see the same kind of suction tube we saw on the enormous Eastern toebiter
- Bugscope Team true bugs..
- Student wow! it looks like there are three sections
- Student are those the eyes on the sides?
- Student is it missing a hair in one follicle?
Bugscope Team it looks that way. Sometimes they can get scraped off
- Teacher what is the fuzzy like thing?
- Student why does it look like sandpaper?
- Teacher those look like stones on a pathway
- Bugscope Team this looks like a softer part of the cuticle because it is more qrinkly
- Bugscope Team wrinkly*
- Bugscope Team this is actually the closest we get to skin on an insect
- Student ah ok
- Student what makes it softer?
Bugscope Team it's actually comparable to what the suction tubes we have been seeing are made of
- Teacher WOW
- Student is this from a spider that we sent?
Bugscope Team yes it is!
- Teacher That looks... hairy
Bugscope Team haha yes and silky, perhaps
- Student is this all part of the spider's body?
Bugscope Team this is external to the spider's body, but note that down below we can see one of its legs, and its claws
- Bugscope Team spiders often have these comb-like claws
- Bugscope Team you see the two larger claws and then smaller 'tines' like a distorted fork
- Teacher internet went down again...
- Teacher sorry
- Bugscope Team you are back, we are happy to see you!
- Student we're all back!
- Teacher more bamboo! yay!
- Student if you say so.
- Bugscope Team this is about 4 times higher in mag and better resolution than you can see using a light microscope
- Bugscope Team big bamboo
- Teacher wow! that is really cool!
- Bugscope Team presently it's 4800x
- Student what is the magnification?
Bugscope Team you can see the magnification at the bottom of the image. we are at 4800x!
- Teacher what is the bump on the side of the bamboo?
Bugscope Team looks to be some dirt
- Teacher it looks like there is a cannon on the left of the bamboo!
- Bugscope Team that is one of the 'tines' of the spider's claw; it is a little bit worn
- Student it was frozen for a bit :)
- Student tines? like a fork?
Bugscope Team yes just like a fort
- Bugscope Team fork
- Teacher fort? like a snowfort? I like snowforts!
- Bugscope Team haha. fork sorry
- Student of topic
- Teacher yes.. it is of topic
- Student off
- Student off topic.
- Teacher thanks
- Teacher can you give RMS2 the controls please?
Bugscope Team they have control
- Student I LIKE PIE
- Student RMS.........
- Student one of our students really enjoys pie :)
- Teacher RMS2 really likes pie...
- Student please forgive him.
- Bugscope Team maybe just this once :)
- Student ok, I am in control now :) and would like to thank you so much for preparing these specimens for us to explore!
- Teacher yeah! thanks!
- Teacher we can go for about 10 more minutes
- Student are these thje mandibles
Bugscope Team yes, in this case they are fangs
- Student the dog from Harry Potter?
- Bugscope Team right now this is more like the giant spider in harry potter
- Student lol
- Student do you want me to come over there?
- Bugscope Team we cannot see the poison pores
- Teacher stay in your seat RMS1
- Student I have a book.
- Teacher If you don't, you will get detention...
- Student ok, they are just being silly, no worries, as we changed the picture.
- Student your not even the teache
- Student this is the last image that we will have time for today.
- Bugscope Team this is the tip of the seta from the silverfish
- Bugscope Team very interesting setae they have
- Bugscope Team the preset was one of the first ones we made this morning, and the specimen drifted a bit in the meantime
- Student setae...
- Student so is this one single hair?
Bugscope Team yes it is!
- Teacher that is one big hair~
- Bugscope Team a single seta
- Bugscope Team lots of the silverfish's setae look like this
- Student i cant remember the name
- Bugscope Team they are weird critters
- Student it looks like the spike off the tail of a....... dinosaur.
Bugscope Team it does. like a stegosaurus
- Teacher well, that is all the time we have. Thanks for having us!
- Student are each of those cone-shaped spikes receptors?
Bugscope Team we are not sure if they are mechanosensors, thermosensors, or chemosensors
- Student we need to get going now, we are going camping :)
- Bugscope Team Thank You!
- Bugscope Team Collect some ticks for us!
- Teacher We hope we can do this again someday!
- Student Thank You!
- Student thank you!!!!!!!!!!!
- Bugscope Team have fun! Thanks for bugscoping with us today!
