- 7:10 am
- Bugscope Teamvac is pumping
- 7:16 am
- Bugscope Teamhey man
- Bugscope Teamhi scott
- Bugscope Teamvac is taking it's time, but we'll be okay
- Bugscope Team2.0 now, started vac about 5 min ago, think it'll be fine?
- Bugscope TeamOtaku there? I'm sorry to be late.
- Bugscope Teamyep, cate is here
- Bugscope Team1.8
- Bugscope TeamSee you soon
- Bugscope Teamk
- 7:26 am
- Bugscope Teamvac is ready, starting presets
- 7:31 am
- 7:37 am
- TeacherDid our specimens make it there?
- 7:43 am
- Bugscope Teamhello, welcome to bugscope, we did get your specimens, but the larva and click beetle were too juicy for the scope
- Bugscope Teamwe are still setting up presets, we'll be done in a few minutes
- Bugscope Teamif you have any questions please let us know
- TeacherAwww. :-( Do you have any on hand? We are interested in decomposers.
- Bugscope Teamwell, this is a pill bug you sent us, and this is a decomposer
- Bugscope Teammaybe i wasn't clear, we put everything you sent us into the scope, except the larva and click beetle
- Teacherthey were my favorites
- Bugscope Teamwe ate a little bit of the caterpillar first though.... ;)
- Bugscope Teamah, sorry
- Bugscope Teamthey were just too juicy and the scope vacuum wouldn't take with them in there
- Bugscope Teamtotally dug the container
- Teacherwe really won't be ready until about 8:10 is this ok?
- Bugscope Teamyep, 8:10 is totally fine
- Teacherok thanks
- Bugscope Teamwe
- 7:48 am
- Bugscope Teamwe'll be online throughout so just let us know when you are ready to start
- 7:53 am
- Bugscope Teamsession unlocked
- Bugscope Teamcool, thanks scott
- Bugscope Teami always forget to unlock
- Bugscope Teammrs. kmiec, anytime you are ready, you should see controls on your right. you have the power.... (to control the scope)
- Bugscope Teamwe lost the vac temporarily, due to a bug being juicy, but we are now resetting, we'll be good to go in a sec
- 8:02 am
- Bugscope Teamspeaking of decomposers, here we see a bunch of mold/mold spores, on the head of a true bug
- Teacherwow i like that - can you keep it there?
- Bugscope TeamMrs K we made it into a preset. We would like to quickly check things since we had that vacuum burp. And then put it back.
- 8:07 am
- Bugscope TeamAlright Mrs K we are ready to roll. You can drive whenever you wish.
- 8:14 am
- Bugscope Teami just passed control of the scope from Mr. Threatt to Mrs. Kmiec
- Bugscope Teamwe an give control to any one person who is logged in, any teacher, student or guest
- Teacherok is this our pillbug
- Bugscope Teamthis is a true bug -- a hemipteran
- Teacherolivia says what is that??
- Bugscope Teamtrue bugs have piercing mouthparts, sometimes to pierce the skin of plants to get to the juices, and sometimes to pierce other insects
- Teacherbroc says - can we see the whole
Bugscope Teamsure, Mrs. K, you have control, so you can click on the - magnification to see more of the whole bug
- Bugscope Teamthese are setae on the head of the true bug
- Teacherthe whole bug??
- Bugscope Teamtake the mag down
- Bugscope Teamthis is real time controlling of an electron microscope. yeah, nice job!
- Bugscope TeamAwesome.
- Bugscope Teamthe min mag is 30-40x, so we are there now
- Teacheris this is eyes?
- Bugscope Teamyou can see the round compound eyes on either side of the skinny head
- 8:19 am
- Bugscope Teamthere are also 2 antennae coming up above the eyes
- Bugscope Teamyep, those bumps on the sides are compound eyes, take a closer look if you like, they are very cool
- Teacherwhat is the long thing??
Bugscope Teamthat is the proboscis
Bugscope Teamthat's the proboscis. a proboscis is an appendage coming from the mouth area, like cate says, the elephant trunk is also a proboscis - the biggest in the world!
- Bugscope Teamand the proboscis which is coming down from the head (from near the top of the head)
- Bugscope Teamyou can't see the tip yet
- Bugscope Teamit's like an elephant's trunk
- Bugscope Teamit is further south
- Bugscope Teambut you can use click to center to drive there
- Bugscope Teamactually we may not be able to see the very tip
- Bugscope Teamsee the claws?
- Teacherwe can see claws on the legs
- Teacherinsects have claws??
Bugscope Teamtotally! and they look really scary in high magnification
- Bugscope Teamthe bug has six legs, and unfortunately they are in front of the tip of the proboscis
- TeacherCarter - what is the hole??
Bugscope Teamthe holes are pores that go into the cuticle, and there are often sensory setae, like the one we see, passing through.
- Bugscope Teamwow, nice depth of field in this image
- Bugscope Teamyou can pull the focus forward onto the claw
- Bugscope Teameach leg has a claw, which is used to grab onto things
- Bugscope TeamInsects have lots of setae that give them information about their surroundings.
- 8:24 am
- Bugscope Teamsetae (see-tee) are kind of like cat whiskers, in that they help insects sense their environment
- Bugscope Teamcool, 42,000x
- Teacherthanks!!
- Teacheractually that is Mr. Threatt driving
- Teacher carter asked if the setea helpwith adaptations
- Bugscope Teamthe setae can be chemosensory -- they can pick up chemical traces in the air or by touch
- Bugscope Teamcompound eyes are very interesting, they are composed of hundreds of bumps, called ommatidia, each one with a lens in it
- Teacherthe eye looks like a golf ball!!
Bugscope Teamtotally, the hexagon shape of the ommatidia help to make the eye surface curved, which gives the insect a wide field of view
- Bugscope Teamsetae can also be mechanosensory -- as Alex mentioned
- Bugscope Teamand some setae sense hot/cold
- Teacheralli = what is the stuff on the eyes??
Bugscope Teamthat's what we like to call juju-- stuff that doesn't belong there like dirt or dust
- Bugscope Teamhexagonal ommatidia on the surface of the eye
- 8:29 am
- Teacherthey are very hairy!! and dirty!!
- Teacherwe are ready for the pill bug!!
- Bugscope TeamSometimes we can see mold spores on the surface of the cuticle, or chitin -- the stuff the exoskeleton is made of.
- Bugscope Teamgo ahead and click on preset #11 for the pill bug
- Bugscope Teamyour pillbug has a lot of dirt on it, so we can't see its face very well
- Teacheri am clicking on the pill bug and it is not working
- Bugscope TeamWe collected our own pillbugs the other day, for another session, and they were dirty as well -- we should have washed them.
- Bugscope Teamwe are working on it now
- Teacherwe are looking at the roach head right now
- Bugscope Teamtry the pill bug again
- 8:34 am
- Bugscope Teamyes, this is the roach head, but you can try the pill bug if you like
- Bugscope Teamthere's the pill bug!
- Teacherok it works
- Bugscope Teamsometimes computers get juju in them.... ;)
- Bugscope Teamsorry the controls would not work for us either, briefly
- Teacherclass - it looks like a crab
- Bugscope Teamthat is a good observation
- Teachersam - where is the mouth??
- Teacherclass = look at the spikey things
- Bugscope Teampillbugs really are crustaceans -- they are related to lobsters and crabs!
- Bugscope Teamthe mouth is covered with debris, which mostly looks like plant material
- Bugscope Teamthe spikey things are the feet
- Bugscope Teamsome of the legs are missing because they must have fallen off though
- Teachercarter = is the leg broken??
Bugscope Teamyep, as the insects dry out, they can become brittle and crack/break
- 8:39 am
- Teacherclass = looks like a guy with a beard!!
- Bugscope Teamthey are called isopods because (iso- means 'the same,' like with an isosceles triangle; and -pod means 'foot') all of their feet are the same.
- Teachercarter = can you tell the age of the pill bug??
- Bugscope Teamit's a guy with a beard full of food!
- Teacherdid our termite make it?
Bugscope Teami think the termite didn't make it
- Teacherwe changed to the caterpillar head!!
- Teacherwhat are the stringy things??
- Teacherwhat about the dots on the eyes??
- Bugscope Teamthere were pieces of it when we received it if I remember correctly
- Teachersomething looks like a band-aid??
- Bugscope Teamthis is very interesting --- a rare view of the inside surface of the caterpillar's cuticle
- Teacherwhat about these dots
Bugscope Teamthese are its simple eyes
Bugscope Teamthese are simple eyes, a compliment (in a way) to the compound eyes
- Teacherwhere are the real eyes??
Bugscope Teamgood question, i don't see them yet???
- Bugscope Teamwe think the fibers we were seeing there are muscles, and the little extruded dots in that area were the inrternal attachments for the muscle fibers.
- 8:44 am
- Teacheris the mouth vertical??
- Bugscope Teamthe real eyes would show up afterwards
- Bugscope Teamtry north for the compound eye?
- Bugscope Teamafter the caterpillar metamorphoses into a moth or butterfly
- Bugscope Teamyes the mouth is vertical, often, in insects
- Bugscope Teamthe jaws are on the sides rather than up and down like ours
- Teacherthere is some type of flap covering the mouth??
- Bugscope Teamyes in adult insects I think it is the clypeus
- Teacherwhat is this thing??
- Bugscope Teamthis is something else that is rotting, decomposing
- Bugscope Teamactually a bacterial biofilm looks much like this
- Bugscope Teamif you go up close perhaps you can see cellulose fibers
- Teacherwe have to log off in 5 minutes, so is there anything else decomposer characteristics of decompsers. to help them break down wood??
- Bugscope Teamplants (and paper) are made of cellulose
- 8:49 am
- Teacherlook claws!!
- Bugscope Teamyes! those are called crochets
- Bugscope TeamYay!
- Bugscope Teamthis is a female housefly
- Teacherhow do you know it is a female??
- Bugscope Teamyou can see its antennae, and here is its compound eye
- Bugscope Teamwith flies the female eyes are often set far apart, whereas those of males are closer together -- like MIkhail Baryshnikov's eyes. For example.
- Bugscope Teamthis is the mouth -- sponging mouthparts
- 8:55 am
- Bugscope Teamtheir saliva helps liquefy their food
- TeacherWe are going to make corn worm houses. we will be back in about 20 minutes. we will stay logged on
- Teacherclass ends at 9:30
- Bugscope TeamCool see you in 20.
- 9:06 am
- GuestWhat are we looking at?
- Bugscope Teamthis is showing a closeup of the jaws of a beetle
- Teacherhello me2 are you from brenham
- Guestno
- GuestIs this a termite?
- Guesta beetle!
- Bugscope Teamhere you can see the mouthparts a little better. this is the view of the mouth from the underside of the head
- Teacherno, not from this class.
- Bugscope Teamthe little feelers are palps, there are 2 sets of palps here
- Bugscope Teamthose are mechanosensory setae on the end of the antenna, which are used to smell/taste things generally
- 9:16 am
- Teacherwhat is an ant lion?
Bugscope Teamthey make pits in the sand, that ants and other small insects will fall into and the antlion will reach out and grab them with their powerful jaws
- Bugscope Teamwe don't always know just what the setae do -- some are chemosensory and pick up chemical scents (smells), some are mechanosensory and pick up tactile information (touch), and some are thermosensory and pick up hot/cold information.
- Teacherwe want to see his jaws
- Bugscope Teampreset 12 shows them pretty well
- Teacherwhere are the jaws from here
- Bugscope Teamnow we are looking at the jaws close up
- Bugscope Teamthey have spines that help them grip their prey
- 9:22 am
- Bugscope Teamthe little rounded things are mites!
- Teacheris this a mite?
- Bugscope Teamthe mites are the tiny round things in a little colony there
- Teacheris this a mite on a leg?
- Bugscope Teamthis is a jaw, mostly, where we are. I think.
- Teacherdo mites have eyes?
- Bugscope Teamsee the ball and socket joint to the right?
- Bugscope Teamsome do have eyes, we didnt see any on these I dont think
- Bugscope Teamif you take the mag out you can see just where we are. And we will see that the ball and socket joint is on a leg, not the jaw
- Teacheris this a nose??
- Bugscope Teamwe are looking at the underside of a beetle's head
- Bugscope Teamso we can see all the mouthparts of the beetle
- Teacherthank you so much for showing us so many things about insects
- Bugscope TeamThank You!
- 9:28 am
- Bugscope TeamWe will see you again at 12:45, right?
