- 3:52 pm
- Bugscope Teamsetting up
- Bugscope Teamvery good samples today
- 3:59 pm
- 4:06 pm
- 4:12 pm
- Bugscope TeamThis is the best set of samples we have ever had.
- 4:17 pm
- Bugscope TeamOkay we are ready to roll.
- 4:24 pm
- Bugscope TeamLeaving the rasper exposed.
- Bugscope Teamthis is the recurved spine side and the upper side is more file-like.
- Bugscope TeamWelcome Aaron!
- Bugscope TeamHi Mr Miller!
- Bugscope TeamI was telling Chas that this is the best set of samples we have ever had in almost 9 years.
- Bugscope TeamCate sonicated them this morning before mounting them.
- Bugscope TeamSoniCate.
- Bugscope TeamYay Claudi!
- Bugscope TeamHello
- TeacherWe are in.
- Bugscope TeamThis is the part of the mouth that sticks into your skin.
- Bugscope Teamawesome
- TeacherThank you about the props for our samples. We tried to get the best we could
- Bugscope TeamClaudi is using some strange German browser we don't recognize.
- TeacherSo, this is the tick?
Bugscope TeamThis is the underside of the head, showing the mouthpart that would stick into your skin with all the recurved spines that keep it from coming out
- Bugscope TeamYou're welcome to let students login simultaneously from more computers if they're available
- Bugscope Teamyes it is
- Bugscope TeamSorry
- Bugscope Teamplease let us know if you have any questions and feel free to drive around
- TeacherWhat are the circular shapes on either side?
Bugscope TeamThose look to be pedipalps, auxiliary mouthparts
- Bugscope TeamI think all of the samples are on and have presets associated with them.
- Bugscope TeamWhat class is this? My mom is watching and is fascinated.
- Bugscope Teamthey are some sort of sensory palps, probably
- 4:30 pm
- Bugscope Teamthe eyespots will be on the dorsal side of the head, and we will not be able to see them
- Bugscope Teamthose arched pieces of the head will separate when the central portion sticks into your skin.
- Bugscope Teamthis is why they don't come out so easily
- Bugscope TeamKind of like the barbs on a harpoon
- Bugscope TeamClaudi say Hi to your mom for us.
- Bugscope Teamyeah like a harpoon
- Bugscope Teamit's 11:30 there. p.m.
- Bugscope TeamScott, I had to use F11 and I cannot see the schools application. Mom says Hi back.
- Bugscope Teamif you get lost take the mag down
- Bugscope Teamthis is the doublestick carbon tape
- TeacherSo, we click drive to move the scope? We seem to be spinning out of control
- Bugscope TeamClick again to stop the driving.
- Bugscope Teamit is a little tricky -- you click to start driving and then click to stop
- Bugscope Teamso sometimes you don't realize you have clicked either way.
- 4:35 pm
- Bugscope TeamClick again inside the image somewhere that is. You click once to start -- once to stop. Once you stop you can return to somewhere interesting using one of the presets at the lower-right corner of the page
- Teacherwe are checking out the presets first
- Bugscope TeamWhoops, I think we're still driving...
- Bugscope TeamI just stopped it. Go ahead and try the preset again
- Teacheryes, oops
- Bugscope Teamtrue bug proboscis
- Bugscope Teamthis is where the sheath has separated and we can see the lancet -- the sharp part -- that is inside
- Teacherthanks for the movement advice. we were a little out of control
- Bugscope Teamif you take the mag down here you can see where you are
- Teacherwhat is behind the lancet. It looks like spider web
- Bugscope Teamif you were to drive north you would see the eyes and the origin of the mouthpart
- Bugscope Teamthat is mold
- Teacherooh, cool
- Bugscope Teamthe stuff that looks like web is mold
- 4:40 pm
- Bugscope Teamyay Smiley is back!
- Teacherwhat are the four holes on either side of the lancet
Bugscope TeamI believe those are empty holes where the legs should be. They must've gotten knocked off during preparation or during travel
- Bugscope Teammosquitos have a similar apparatus
- Bugscope Teamthose holes may be where the limbs are missing
- Bugscope Teamyou are getting more proficient at driving
- Bugscope TeamAnnie!
- Bugscope Teamhooray, it worked
- Bugscope TeamI told them this was a crab...
- Bugscope TeamI am just back from California
- Bugscope TeamYou didn't stay long, apparently
- Bugscope TeamI am explaining my mom and translating as we go...yeah!!!
- Bugscope Teamtell your mom I am trying to get Annie to say NO NO this is a true bug
- Bugscope Teamright right---this is a hemiptera of some description
- Bugscope TeamYay SoniCate.
- Bugscope TeamAnnie are you in town here?
- Bugscope TeamNope, I am in Kentucky
- Bugscope Teamthe eye!
- Bugscope TeamOOF
- Bugscope Teamoh yeah good job focusing
- 4:46 pm
- Teacherwhy thank you
- TeacherWhat is that stuff on the eye?
- Bugscope Teamjuj
- Bugscope Teamjuju
- Teacher???
- Bugscope Teamjuju is our catch-all term for dirty and junk that we see on the insects
- Bugscope Teamit's some slime that might have come out of the bug when it died
- Teacherok that's what we thought. we'll use it too
- Bugscope Teamthis is pretty rad too
- Bugscope Teammy mom is thrilled...I showed her the omatitia on the compound eye
- Bugscope Teamdouble clipping jaws
- Bugscope Teamcool--what is this?!
- Teacherso there are two sets of jaws?
- Bugscope Teamyour mom is staying up late for this
- Bugscope Teamscorpion
- Bugscope Teamit's a baby lobster
- Bugscope Teamawesome!
- Teacherso the hairs are called setae?
- Bugscope Teamthats right
- Bugscope Teamyes
- Bugscope Teamsome of them are mechanosensory, as these likely are
- Bugscope TeamInterestingly daddy-long-legs spiders have a very similar pair of pincers due to their being in the crustacean family rather than being true spiders
- Bugscope Teamand some are chemosensory
- 4:51 pm
- Bugscope TeamActually, daddy longlegs are arachnids, but not spiders
- Teacheris that connective tissue in the mouth?
- Bugscope Teamsome chemosensory setae have receptors for only one chemical, and some can sense more than one chem.
- Bugscope Teamnot true spiders anyway
- Bugscope TeamWhoops, sorry for the mis-information.
- Bugscope Team;)
- Bugscope Teamit is confusing
- Bugscope Teamthat is probably my fault since I am convinced that DDLs are crabs
- Bugscope Teamopiliones
- Bugscope TeamIt's also confusing that the daddy long-legs name applies to two both Opiliones and Crane flies
- Bugscope Teammy mom thinks it is awesome. enjoy the rest of this session. see you guys next year
- Bugscope Teamharvestmen too
- Bugscope TeamThanks Claudi!
- Bugscope Teamthat is confusing---and that is one of the problems with common names
- Bugscope TeamI believe harvestmen and opiliones are one and the same.
- Bugscope TeamEnjoy Germany, Claudi!!
- Bugscope TeamYes, as far as I know, harvestmen and opiliones and daddylonglegs are all the same
- Bugscope TeamClaudi is r-u-n-n-o-f-t.
- Bugscope TeamI know what this is!!!!
- Bugscope TeamWith the pore showing
- 4:56 pm
- Bugscope Teamthere is a longhorned beetle with a stinging antenna tip with a pore like this
- Bugscope Teamyeah Cate made the sample and did a great job, with drawings
- Bugscope TeamOOF
- Bugscope Teamand they sting too!
- Bugscope TeamOh I want to see that
- Bugscope TeamNice, Mr M. You are a pro.
- Bugscope Teamthose drawings were awesome i know
- Bugscope Teamthe eightball esp.
- Teacherwhat is OOF?
- Bugscope Teamout of focus
- Bugscope Teamwell it's not now
- Bugscope TeamOut Of Focus
- Bugscope Teamthey look exactly like this! It is really remarkable
- Teacherexcellent job preparing these. They look awesome?
- Bugscope TeamYeah, they are really nice!
- Bugscope Teamyes they do
- Bugscope Teamcould be crystallized poison
- Bugscope TeamLooks like something in the canal here dried up
- Bugscope Teamspider fangs are similar when you get to see them
- Teacherwhat are the small black dots here?
Bugscope Teamnot really sure what these small pores actually do
- Bugscope Teamtiny pores
- 5:01 pm
- Bugscope TeamMr M it is hard to focus here because we are pretty far from the polepiece and I left a tiy bit of astigmatism in the image, apparently
- Bugscope Teamxtals
- Teacherno worries
- Teacherdo you know what kind of crystals?
- Bugscope Teamthis is on the fly eye; to the right is some of the vestiture
- Bugscope TeamLooks more elongated than regular salt, so it might be crystals of something else
- Bugscope Teamwe see them sometimes but yeah like Chas says they are likely not NaCl.
- Bugscope Teamthis fly did not fare too well
- Bugscope Teambut this part looks great
- Bugscope Teamif we were to do EDS we might be able to figure out what elements are in the extals
- Bugscope Teamwe will save this sample and might be able to find out tomorrow
- Bugscope TeamEDS is energy-dispersive spectroscopy -- elemental analysis
- Bugscope TeamEDS stand for energy dispersive spectroscopy. The bombardment of the sample by electrons, how we're imaging, also produces X-rays. The exact wavelength of the X-rays produced can tell us about the atomic composition of what we steer the beam at
- Teacherumm, what is vestiture, looks like french fries
- Bugscope Teamhehe french fried
- Bugscope Teamwe can detect either the wavelength or the energy of the x-rays
Bugscope TeamThese are actually equivalent, but you can sense them in two different ways. One physically spreads the wavelengths out like a prism separates the colors of light. Another counts the number of electrons liberated by the X-ray hitting the detector, sensing the energy deposited
- Bugscope Teamfries
- Bugscope Teamit's like fur on the head between the eyes
- Teachercool
- Bugscope Teamvestiture like a dress is a vestido; it's like the dressing on the head
- 5:06 pm
- Bugscope Teamnow you can see where the larger setae, like bristles, were
- Bugscope TeamNow you can see some moth scales lying on the compound eye there.
- Teacherwhat are the craters on the vestiture?
Bugscope TeamThose look like empty pores that large hairs, "setae", would have been coming out of
- Teacherooh, moth scales
- Bugscope Teamthose are pores where the setae were
- Bugscope Teamsockets, I guess
- Teacherwhich way is the mouth?
Bugscope TeamTo the lower right
- Bugscope TeamThey have a very distinctive shape and texture, making them easy to identify
- Bugscope Teamit would have been to the south but it is way gone
- Bugscope Teamthe antennae are missing, as are the mouthparts
- Bugscope Teamthere's a mouth for you
- Bugscope Teamif you take the mag down you can see where you are
- Teacherwhy are there setae in the mouth?
- 5:12 pm
- Bugscope Teamfor tasting/smelling
- Bugscope Teamsome of them could be chemosensory, like taste buds
- Bugscope Teamdifferent setae have different functions as you have gathered
- Bugscope Teamand some could just filter the food
- Bugscope Teamkeep it from crawling back out of the mouth
- Bugscope Teamsome, like on an eye, will tell the insect which way the wind currents are going
- Bugscope Teamothers are sensitive to vibration, like on a spider
- Bugscope Teamladybugs eat other bugs
- Bugscope Teamhere you can see the jaws, like crossed hinged gates
- Bugscope Teamabove
- Bugscope Teamthe big setae are prob'ly the mechanosensors
- Bugscope Teammandibular palps
- Bugscope Teamthe stalk like things
- Teacherare those small legs around the mouth?
Bugscope TeamThose are called pedi-palps. They usually act in a complex coordinated way to help manipulate the food and shove it into their mouths. They do a lot of the functions we would use our tongue for.
- Teacheryou read our minds
- Teacherdo the palps break up food our just feel?
Bugscope Teampalps taste and feel, but don't "chew"
- Bugscope Teamthe centers of the ends of the palps, as you can see on the left, have what we think are chemosensory setae in them
- 5:17 pm
- Bugscope Teamladybugs also have larger maxillary palps that look like vacuum cleaner nozzles
- Bugscope Teamhere we go
- Bugscope Teamnow you can see the chemosensory setae inside
- Teacherit looks like a cactus fruit or bee hive
- Bugscope Teamthis is kind of cool too
- Bugscope Teamyeah they have vacuum cleaner palps and bee hive palps
- Teacherwhere are these setae located
- Bugscope Teamthis is cool
- Bugscope Teamthis is near the head i think
- Bugscope Teamspiders almost always have these totally awesome-lookin' setae
- Teacherwhat do these setae do?
- Bugscope TeamI think they are vibration sensing
- Bugscope Teami don't know much about spider hairs
- 5:22 pm
- Bugscope Teambut Chas had brought up the idea of the shape having the ability to shed web silk
- Bugscope Teamthey don't have flat surfaces for something sticky to adhere to.
- TeacherAre those little bugs on the spider? look like caterpillars or leeches
- Bugscope TeamI think those setae were on a leg, but spiders have similar setae everywhere
- Bugscope Teamthe round things are four of the eyes
- Bugscope TeamI think we are looking at fungal hyphae on this tick claw
- Teacherwow, fungus
- Teacherhow many claws does it have total
- Teacheris a tick an arachnid?
Bugscope Teamyes, it is. It was eight legs. Mites and chiggers are arachnids too. And scorpions and horseshoe crabs.
- Bugscope TeamI think it would have 16
- 5:27 pm
- Bugscope Teamif it has two claws on each arm
- Bugscope Teambut it does have a set of extra claw like things that it uses to perch
- Bugscope Teamlike to perch on leaves
- Bugscope Teamthat should have read 'has', not was
- Bugscope Teamresolution standard built into the wings of a cicada
- Bugscope Teamthe astigmatism is not that bad
- Bugscope Teamyou can see from the micron bar that the dots are submicron -- they are nanoscale
- Teacheris that a setae or a wing vein?
- Bugscope Teamit's a seta on a wing vein
- Bugscope Teamif you take the mag down a bit you can see
- Bugscope Teamthere...
- 5:32 pm
- Bugscope Teamthat is pretty cool
- Bugscope TeamI didn't expect to see that detail on a cicada
- Teacherwhat is that ball on the setae
- Bugscope Teamjuju
- Teacherthat dang juju
- Bugscope Teamyeah it is some oily substance we don't know where it comes from
- Bugscope Teamthis is a pattern I don't remember seeing in the past
- Bugscope Teamvery beautiful architecture to the scale on the butterfly wing
- Bugscope Teamhave a great night everyone! Gotta go for now.
- Bugscope Teamhappy bugscoping!!!!!
- Bugscope Teamreally? what color were the wings? grey?
- Bugscope Teamthis is another moth's eye
- Teacherit looks like fingerprints on the eye
- Bugscope Teamwell I guess this is the first moth we have see today
- Teacherbrown with blue and orange
- 5:37 pm
- Bugscope Teammoths seem to have the finest substructure on their eyes
- Teacheri wonder why? seeing at night?
- Bugscope TeamI have this idea that the microarchitecture of the scale is responsible for the color
- Bugscope TeamMr M maybe so. I had been thinking UV but maybe they are like rods/cones, whichever one is best at night
- Bugscope Teamrods?
- Bugscope Teamrods i believe
- Bugscope Teambubba
- Bugscope TeamOops we lost Mr M.
- Teacherwow this is cool
- Bugscope Team200,000x
- Bugscope Teamnow the working distance makes a big difference in the res.
- 5:42 pm
- Teacherwe were just trying to zoom in on the rods
- Bugscope Teamif we were closer to the electron source we would get better imaging
- Bugscope Teamsorry I placed us about an inch away
- Bugscope Teamfor shame scott
- TeacherWell thanks for your time. We need to sign out. Thank you for staying late
- Bugscope Teamyou can see that the rods are around 100 nm across -- smaller than the wavelength of UV, even.
- Bugscope Teamwe hope you had fun
- TeacherMerry Christmas and happy new year from the kids. This was the best ever, after met
- Bugscope Teamscott is trying to make the image better
- Teachercool looks awesome
- Bugscope TeamI can bring it closer...
- TeacherWe saw those closer images thanks for doing that!
- 5:48 pm
- Bugscope Teamwhen we get too close the electron beam affects the sample
- Bugscope Teambut that is a little better
- Bugscope Teamnow I probably messed up all of the rest of the presets
- Bugscope Teamyep
- Bugscope Teambut thats ok
- TeacherWell that's okay our session is about over.
- TeacherI'll be applying again. The kids really liked it!
- Bugscope TeamWell perfect, then. Mr M we had a great session, Thank You.
- Bugscope TeamYeah be sure to come back.
- Bugscope TeamMerry Christmas to you as well.
- Bugscope TeamYou know the images and text are available on the page under your login.
- Bugscope TeamAnd email us if you have any problems getting to them.
- Bugscope TeamI am shutting down now...
- TeacherUs too.
- Bugscope Teamcool!
- Bugscope TeamThank You!
