- 7:10am
- Bugscope Team vac is pumping
- 7:16am
- Bugscope Team hey man
- Bugscope Team hi scott
- Bugscope Team vac is taking it's time, but we'll be okay
- Bugscope Team 2.0 now, started vac about 5 min ago, think it'll be fine?
- Bugscope Team Otaku there? I'm sorry to be late.
- Bugscope Team yep, cate is here
- Bugscope Team 1.8
- Bugscope Team See you soon
- Bugscope Team k
- 7:26am
- Bugscope Team vac is ready, starting presets
- 7:31am
- 7:37am
- Teacher Did our specimens make it there?
- 7:43am
- Bugscope Team hello, welcome to bugscope, we did get your specimens, but the larva and click beetle were too juicy for the scope
- Bugscope Team we are still setting up presets, we'll be done in a few minutes
- Bugscope Team if you have any questions please let us know
- Teacher Awww. :-( Do you have any on hand? We are interested in decomposers.
- Bugscope Team well, this is a pill bug you sent us, and this is a decomposer
- Bugscope Team maybe i wasn't clear, we put everything you sent us into the scope, except the larva and click beetle
- Teacher they were my favorites
- Bugscope Team we ate a little bit of the caterpillar first though.... ;)
- Bugscope Team ah, sorry
- Bugscope Team they were just too juicy and the scope vacuum wouldn't take with them in there
- Bugscope Team totally dug the container
- Teacher we really won't be ready until about 8:10 is this ok?
- Bugscope Team yep, 8:10 is totally fine
- Teacher ok thanks
- Bugscope Team we
- 7:48am
- Bugscope Team we'll be online throughout so just let us know when you are ready to start
- 7:53am
- Bugscope Team session unlocked
- Bugscope Team cool, thanks scott
- Bugscope Team i always forget to unlock
- Bugscope Team mrs. kmiec, anytime you are ready, you should see controls on your right. you have the power.... (to control the scope)
- Bugscope Team we lost the vac temporarily, due to a bug being juicy, but we are now resetting, we'll be good to go in a sec
- 8:02am
- Bugscope Team speaking of decomposers, here we see a bunch of mold/mold spores, on the head of a true bug
- Teacher wow i like that - can you keep it there?
- Bugscope Team Mrs 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.
- 8:07am
- Bugscope Team Alright Mrs K we are ready to roll. You can drive whenever you wish.
- 8:14am
- Bugscope Team i just passed control of the scope from Mr. Threatt to Mrs. Kmiec
- Bugscope Team we an give control to any one person who is logged in, any teacher, student or guest
- Teacher ok is this our pillbug
- Bugscope Team this is a true bug -- a hemipteran
- Teacher olivia says what is that??
- Bugscope Team true bugs have piercing mouthparts, sometimes to pierce the skin of plants to get to the juices, and sometimes to pierce other insects
- Teacher broc says - can we see the whole
Bugscope Team sure, Mrs. K, you have control, so you can click on the - magnification to see more of the whole bug
- Bugscope Team these are setae on the head of the true bug
- Teacher the whole bug??
- Bugscope Team take the mag down
- Bugscope Team this is real time controlling of an electron microscope. yeah, nice job!
- Bugscope Team Awesome.
- Bugscope Team the min mag is 30-40x, so we are there now
- Teacher is this is eyes?
- Bugscope Team you can see the round compound eyes on either side of the skinny head
- 8:19am
- Bugscope Team there are also 2 antennae coming up above the eyes
- Bugscope Team yep, those bumps on the sides are compound eyes, take a closer look if you like, they are very cool
- Teacher what is the long thing??
Bugscope Team that is the proboscis
Bugscope Team that'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 Team and the proboscis which is coming down from the head (from near the top of the head)
- Bugscope Team you can't see the tip yet
- Bugscope Team it's like an elephant's trunk
- Bugscope Team it is further south
- Bugscope Team but you can use click to center to drive there
- Bugscope Team actually we may not be able to see the very tip
- Bugscope Team see the claws?
- Teacher we can see claws on the legs
- Teacher insects have claws??
Bugscope Team totally! and they look really scary in high magnification
- Bugscope Team the bug has six legs, and unfortunately they are in front of the tip of the proboscis
- Teacher Carter - what is the hole??
Bugscope Team the holes are pores that go into the cuticle, and there are often sensory setae, like the one we see, passing through.
- Bugscope Team wow, nice depth of field in this image
- Bugscope Team you can pull the focus forward onto the claw
- Bugscope Team each leg has a claw, which is used to grab onto things
- Bugscope Team Insects have lots of setae that give them information about their surroundings.
- 8:24am
- Bugscope Team setae (see-tee) are kind of like cat whiskers, in that they help insects sense their environment
- Bugscope Team cool, 42,000x
- Teacher thanks!!
- Teacher actually that is Mr. Threatt driving
- Teacher carter asked if the setea helpwith adaptations
- Bugscope Team the setae can be chemosensory -- they can pick up chemical traces in the air or by touch
- Bugscope Team compound eyes are very interesting, they are composed of hundreds of bumps, called ommatidia, each one with a lens in it
- Teacher the eye looks like a golf ball!!
Bugscope Team totally, the hexagon shape of the ommatidia help to make the eye surface curved, which gives the insect a wide field of view
- Bugscope Team setae can also be mechanosensory -- as Alex mentioned
- Bugscope Team and some setae sense hot/cold
- Teacher alli = what is the stuff on the eyes??
Bugscope Team that's what we like to call juju-- stuff that doesn't belong there like dirt or dust
- Bugscope Team hexagonal ommatidia on the surface of the eye
- 8:29am
- Teacher they are very hairy!! and dirty!!
- Teacher we are ready for the pill bug!!
- Bugscope Team Sometimes we can see mold spores on the surface of the cuticle, or chitin -- the stuff the exoskeleton is made of.
- Bugscope Team go ahead and click on preset #11 for the pill bug
- Bugscope Team your pillbug has a lot of dirt on it, so we can't see its face very well
- Teacher i am clicking on the pill bug and it is not working
- Bugscope Team We collected our own pillbugs the other day, for another session, and they were dirty as well -- we should have washed them.
- Bugscope Team we are working on it now
- Teacher we are looking at the roach head right now
- Bugscope Team try the pill bug again
- 8:34am
- Bugscope Team yes, this is the roach head, but you can try the pill bug if you like
- Bugscope Team there's the pill bug!
- Teacher ok it works
- Bugscope Team sometimes computers get juju in them.... ;)
- Bugscope Team sorry the controls would not work for us either, briefly
- Teacher class - it looks like a crab
- Bugscope Team that is a good observation
- Teacher sam - where is the mouth??
- Teacher class = look at the spikey things
- Bugscope Team pillbugs really are crustaceans -- they are related to lobsters and crabs!
- Bugscope Team the mouth is covered with debris, which mostly looks like plant material
- Bugscope Team the spikey things are the feet
- Bugscope Team some of the legs are missing because they must have fallen off though
- Teacher carter = is the leg broken??
Bugscope Team yep, as the insects dry out, they can become brittle and crack/break
- 8:39am
- Teacher class = looks like a guy with a beard!!
- Bugscope Team they are called isopods because (iso- means 'the same,' like with an isosceles triangle; and -pod means 'foot') all of their feet are the same.
- Teacher carter = can you tell the age of the pill bug??
- Bugscope Team it's a guy with a beard full of food!
- Teacher did our termite make it?
Bugscope Team i think the termite didn't make it
- Teacher we changed to the caterpillar head!!
- Teacher what are the stringy things??
- Teacher what about the dots on the eyes??
- Bugscope Team there were pieces of it when we received it if I remember correctly
- Teacher something looks like a band-aid??
- Bugscope Team this is very interesting --- a rare view of the inside surface of the caterpillar's cuticle
- Teacher what about these dots
Bugscope Team these are its simple eyes
Bugscope Team these are simple eyes, a compliment (in a way) to the compound eyes
- Teacher where are the real eyes??
Bugscope Team good question, i don't see them yet???
- Bugscope Team we 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.
- 8:44am
- Teacher is the mouth vertical??
- Bugscope Team the real eyes would show up afterwards
- Bugscope Team try north for the compound eye?
- Bugscope Team after the caterpillar metamorphoses into a moth or butterfly
- Bugscope Team yes the mouth is vertical, often, in insects
- Bugscope Team the jaws are on the sides rather than up and down like ours
- Teacher there is some type of flap covering the mouth??
- Bugscope Team yes in adult insects I think it is the clypeus
- Teacher what is this thing??
- Bugscope Team this is something else that is rotting, decomposing
- Bugscope Team actually a bacterial biofilm looks much like this
- Bugscope Team if you go up close perhaps you can see cellulose fibers
- Teacher we have to log off in 5 minutes, so is there anything else decomposer characteristics of decompsers. to help them break down wood??
- Bugscope Team plants (and paper) are made of cellulose
- 8:49am
- Teacher look claws!!
- Bugscope Team yes! those are called crochets
- Bugscope Team Yay!
- Bugscope Team this is a female housefly
- Teacher how do you know it is a female??
- Bugscope Team you can see its antennae, and here is its compound eye
- Bugscope Team with flies the female eyes are often set far apart, whereas those of males are closer together -- like MIkhail Baryshnikov's eyes. For example.
- Bugscope Team this is the mouth -- sponging mouthparts
- 8:55am
- Bugscope Team their saliva helps liquefy their food
- Teacher We are going to make corn worm houses. we will be back in about 20 minutes. we will stay logged on
- Teacher class ends at 9:30
- Bugscope Team Cool see you in 20.
- 9:06am
- Guest What are we looking at?
- Bugscope Team this is showing a closeup of the jaws of a beetle
- Teacher hello me2 are you from brenham
- Guest no
- Guest Is this a termite?
- Guest a beetle!
- Bugscope Team here you can see the mouthparts a little better. this is the view of the mouth from the underside of the head
- Teacher no, not from this class.
- Bugscope Team the little feelers are palps, there are 2 sets of palps here
- Bugscope Team those are mechanosensory setae on the end of the antenna, which are used to smell/taste things generally
- 9:16am
- Teacher what is an ant lion?
Bugscope Team they 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 Team we 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.
- Teacher we want to see his jaws
- Bugscope Team preset 12 shows them pretty well
- Teacher where are the jaws from here
- Bugscope Team now we are looking at the jaws close up
- Bugscope Team they have spines that help them grip their prey
- 9:22am
- Bugscope Team the little rounded things are mites!
- Teacher is this a mite?
- Bugscope Team the mites are the tiny round things in a little colony there
- Teacher is this a mite on a leg?
- Bugscope Team this is a jaw, mostly, where we are. I think.
- Teacher do mites have eyes?
- Bugscope Team see the ball and socket joint to the right?
- Bugscope Team some do have eyes, we didnt see any on these I dont think
- Bugscope Team if 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
- Teacher is this a nose??
- Bugscope Team we are looking at the underside of a beetle's head
- Bugscope Team so we can see all the mouthparts of the beetle
- Teacher thank you so much for showing us so many things about insects
- Bugscope Team Thank You!
- 9:28am
- Bugscope Team We will see you again at 12:45, right?
