- Bugscope TeamWe're finishing up a few more presets for the microscope.
- 12:14 pm
- Bugscope TeamWe are ready to go
- 12:21 pm
- 12:27 pm
- 12:41 pm
- Bugscope TeamHello!
- Bugscope TeamHi Mrs. Evans
- Bugscope TeamWelcome to Bugscope!
- Bugscope TeamGood morning.
- Bugscope TeamCan you see the screen, with the arrows in blue circles on each side?
- TeacherCool We made it! Thanks!
- TeacherI made it!
- Bugscope TeamPresently we're looking at honeybee setae. They're branched.
- Bugscope TeamHi Lucas!
- Bugscope TeamWe've run into a few glitches ourselves, need to wait, sometimes, for things to work
- Bugscope Teamthe central screen is what is live
- Bugscope Teamthe left screen shows the preset positions we made earlier
- Bugscope Teamthe right screen shows who's on board
- Bugscope Teamwow I wonder if we're seeing brochosomes on those little branches
- Bugscope TeamThey sure look like brochosomes. I'll zoom in.
- Bugscope TeamI believe honeybees are the only insects that have branched setae
- Guestwhat is it?
- StudentThat's cool
- 12:47 pm
- Bugscope Teamthis is just some juju on the seta
- Guestwait you didnt answer
- Bugscope Teamhi Wes
- Bugscope Teamlike frass or just whatever was floating in the air
- Guesthow small can a bee be?
Bugscope TeamThe tiniest ones are a sixteenth of an inch long.
- Bugscope Teamthis is not Hunter's fly -- it's the bee's head
- TeacherI'm here!!!!
- Studentthat is so cool
- Bugscope TeamHere's the honeybee's head. Hunter's fly in a minute!
- Bugscope TeamWelcome, guys!
- Bugscope TeamHello Jonah!
- Bugscope TeamHello Ananya
- Guestnast but cool
- Teachernumerous stuff
- Bugscope Teamthis is a cool bee head. Look at all the setae (bug hairs) on its eye
- TeacherI ate breakfast before this
Bugscope TeamBees and flies taste like paper, not that big of a deal
- TeacherOh my
- Guestthats pretty cool
- TeacherThis is cool
- Bugscope Teamnow we're powering right into the compound eye
- Teacherlook at that little eye
Bugscope TeamHi Anthony!
- TeacherDont zoom in too much to where you poke his eye out
- GuestMan the amout of detail.
- Bugscope Teamthe little facets are called ommatidia
- Bugscope Teamlike tiny individual eyes
- GuestIf it does not cost a fortune.
- Teacherwe're too close we're gonna kill it
- 12:52 pm
- TeacherNo color :/
- TeacherCan we see the grasshopper?
- Teacheri wanna see the tick
- Bugscope TeamThe hair, which we are supposed to called setae, are sensory -- that is, they can help the bee feel wind currents and touch
- Teacherme plz
- Bugscope TeamSo they do, in a way, transmit feeling, maybe not itchiness
- GuestDo not know how to control.
- Teacherit would do the opposite
- Bugscope Teamthe ommatidia are hexagonal, and sometimes pentagonal
- GuestI really do not know anything about insects then.\
- Bugscope Teamcan you see the fly haltere now?
- TeacherOh cool! The fly!!
- Bugscope TeamJustin's fly, part of it.
- Teachernot eww
- Teacherit is bootiful
- Bugscope TeamHunter's. Oops.
- Bugscope Teamthis is on Hunter's fly
- Guestwouldnt that hair make its eye itchy?
- Bugscope Teamnormally the end on the left side would be swollen like a tiny basketball
- Teacherit looks like an elephant trunk sorta
- TeacherIt looks like an old horn or something
- Teacherone of those weird bugs with the long face or whatever
- Guestisnt that the mouth?
- Teacherits hairy now
- Bugscope Teamyou can see, toward the body, where the haltere has little sensilla that help sense the movement of the haltere
- Teacherhairy boi
- Bugscope Teamso this has deflated since the fly was alive
- Bugscope TeamIt's a little pendulum between the wings, to help it fly stable even in gusty winds.
- Teacherluckily my mouth isn't that deformed
- Bugscope TeamI'll zoom out to show you where.
- Bugscope Teamflies balance themselves in the air when they fly by moving the halteres opposite the way the wings move
- GuestLooks like a flex of fungi.
- 12:57 pm
- GuestRest in Peace.
- Bugscope Teamkind of an unhappy fly, Hunter, but it let us see some things we don't usually see very well
- Teacherdead widow fly
- Teachercool scot
Bugscope TeamThanks, Wayne
- Teachermine was blue for 2 seconds
- Bugscope Teamlet us know if you are having problems driving, Mrs Evans
- Bugscope Teamhead fell off, yeah Anthony. RIP
Bugscope TeamBut we've seen even worse samples arrive over the years...!
- Teacherdead head window fly
- Teacheris it possible to see the grasshopper?
- Bugscope Teamdrove off the edge of the world
- Teacheri think so
- StudentPoor fly
- GuestEven Worse?
- Teacherhe ded
- Guesti think so
- Bugscope TeamCamille is driving us to the grasshopper
- Bugscope Teamyou can see a number 2 on the stage. the bug platter is to the right
- Bugscope TeamAnd Cate had a put a fly with a head next to Hunter's fly, so we can check that out as well...
- Teacherhes still dead tho
- Bugscope Teamthat's the honeybee
- TeacherWhat is th green thing on the picture
- Teacher: /
- Bugscope TeamJust a moment.
- StudentWeird, but still cool
- 1:03 pm
- Guestwhat bug is this?
- Teacherhow about another image?
Bugscope TeamButterfly wing scales.
- Teacherwow ticks have scales!
- Teacherwhere do I request to control it
Bugscope TeamMrs. Evans is controlling it now. We can't have ten pilots for one airplane :-)
- TeacherLooks like the rooftop of a house
Bugscope TeamShingles, fish scales, same idea, yes.
- GuestIt seems that every insect has features that the naked human eye can't see.
Bugscope TeamYes, there's a lot of cool structures at this size.
Bugscope Teamyes they are often hairier than they seem
- Bugscope Teamthis is cool
Bugscope Teambutterflies, moths, and some beetles have scales, which are kind of like hairs for them
- TeacherWhat are the scales for?
Bugscope Teamthey function much like feathers do in bird wings
- Bugscope TeamScales also often reflect or produce color, as in butterfly wings
- Bugscope TeamSometimes the scales flake off when the bug is trying to escape a spider's web.
- GuestEven then, their's features about the human body that the naked eye can't see.
- 1:08 pm
- Bugscope TeamSome of the color comes from pigment; some of the color may be 'structural,' meaning that the shape of the tiny components of the scales interferes with light and produces various colors without pigment
- Guestthis is scientifically cool
- Teacherthe tools are not doing it for us,
- Bugscope TeamAnd there's another kind of cool thing about scales: they come off easily, and that means that if the insect flies into a spiderweb the scales may stick to the web but the insect can get away
- GuestEven then, their are features about the Human body we cannot see with our naked eyes.
- Teachercan we zoom out on this ticke head?
Bugscope TeamJust a few seconds, sorry...
- Guestthis is scientifically cool
- Bugscope Teamso silverfish, those things you find around books and in crevices in your house, sometimes, also have scales
- Bugscope Teamtheir scales reflect light we see as silver
- Bugscope Teamand their scales also help them get out of spiderwebs
- Bugscope Teamwe're calling them baby ticks because they have only six legs
- Bugscope Teamadult ticks have eight legs
- TeacherCool ...can we see the spider face?
- GuestAll scales are like armor for the Insect.
Bugscope TeamMost bugs' skin *is* armor. The hard skeleton is on the outside, instead of bones on the inside.
- Bugscope Teamnow we can see what the tick sticks into your skin -- the hypostome
- GuestIt looks like theres dust on it.
- 1:13 pm
- Bugscope Teamah here is the hypostome, up close
- Guest*Theirs dust
- Bugscope TeamSpider face.
- Guestthis is scientifically cool
- Bugscope Teamreally their exoskeleton is like a suit of armor
- Bugscope Teamso we are looking at the face from the underside
- Bugscope Teamwe can see four of the spider's eyes to the top left
- Bugscope Teamtwo of the eyes are in the center and look like a kind of ridge
- Bugscope Teamyou can see the fangs, and the big chelicerae they're mounted in
- GuestImagine being eaten by that.
Bugscope TeamMost spiders are pretty good hunters. Om nom nom.
- Bugscope Teamsometimes we can see the poison ducts at the tips of the fangs
- GuestIs there little crack on there.
- Bugscope Teamwe're calling the tooth-like things above the fangs the retention plan
- Guestis ths cool?
- Bugscope TeamSounds like some corporate policy, but it's just how the spider keeps its fang (the long spike) in what it's eating.
- Bugscope Teamthey help hold the prey so the fangs can pierce the spider's prey
Bugscope Teamdepartment of redundancy department, sorry
- Guest* Is their a little crack on there.
Bugscope Teamyes it seems that it had some liquid dry on it and it cracked like dried mud
Bugscope Teamthe crack is probably in a dried fluid that is on the spider's face there
- Bugscope Teamthis is one of the fangs and one of the accessory toothlike elements
- Bugscope Teamwe're also seeing a bit of web
- 1:18 pm
- Bugscope TeamThere's some kind of hairs or threads above the fang. The scope just can't focus on the hair and the fang at the same time.
- Bugscope Teamthe thin double fiber
- Bugscope Teameven the fangs have little setae on them
- GuestEven looks like theirs little scales.
- TeacherOk cool! Thanks!
- TeacherWas the grasshopper available?
Bugscope Teamjust a sec; we'll try to get it
Bugscope TeamHere we go...!
- Guestwhats a haltere
Bugscope TeamIt's a pendulum between wings, to make flies fly more smoothly.
- Guestwow my bearded dragon eats those
- Bugscope Teamgrasshopper head!
- Bugscope TeamGrasshopper isn't as scary as the spider.
- Bugscope Teamthe little armlike things are palps, used to help manipulate food and also help taste prospective food
- Bugscope Teamwe can see that one of the forelimbs, to the left, is broken off
- 1:24 pm
- Bugscope Teaminsects have hemolymph instead of blood, and it doesn't circulate like blood; much of the inside of the body is filled with it
- Guestwow my bearded dragon eats those grasshoppers
Bugscope TeamIt can probably see them better than us people - we need a microscope for that :)
- GuestWhat's that jelly like subtansce.
- Bugscope TeamLittle hairs on the grasshopper's forelegs.
- Bugscope Teamthese spines, which are usually called setae, can be mechano-, chemo-, and/or thermosensory
- Bugscope Teamfor example if the insect moves its limbs, there are setae that can sense that motion
- Teacheris the meholymph like human blood because when you freeze a bug they die
Bugscope TeamYes. But bugs are so small that they don't need a heart to pump it around.
- Teacherthat really cool
- Bugscope Teambeing an insect or similar arthropod means that you are wearing a shell, like a suit of armor, all of the time
- Bugscope Teamthe setae stick through the suit of armor and help the insect/arthropod sense its environment
- Bugscope Teamsome of the spines help with proprioception
Bugscope TeamThe spines are like a cat's whiskers, that feel things.
Bugscope TeamBTW I just learned that cats need whiskers because their eyes can't focus on something that close. Their eyes are only good for spotting prey far away.
- TeacherThank you so much!! We are wrapping up
- Bugscope Teamthey're connected to a nerve structure beneath the cuticle (the exoskeleton, or shell)
- Guestbye scott
Bugscope TeamBye Justin. Thank you for joining us today!
- 1:29 pm
- Bugscope Teambye thanks for joining us today!
- Teacherdo bugs have a small brain
Bugscope TeamYes. Just big enough to understand what they can see, feel, and smell.
- TeacherWe had 56 students in my room experiencing this. We so appreciate you!
- GuestWHAT IS BIGGEST BUG?
Bugscope TeamIt's extinct now, but the griffinflies were insects over two feet wide.
- Teacherhow cool! i best be doing my home work have a wonderfulday
- Bugscope Teamwe can see that the grasshopper is vignetted -- there are shadows around the edge of the image we see. that shows us that we are at a very low magnification for this microscope
- Bugscope Teamthe background is doublestick carbon tape, and everything in the image has been coated with gold-palladium to make it conductive, so the critters we are looking at do not charge up with electrons
- Bugscope Teamthis is pretty cool
- Bugscope Teamthe little hooks we see are on the bee's forewings
- 1:34 pm
- Bugscope TeamWe're going to shut down in a few minutes. Thank you, Everyone!
- Bugscope TeamBye! Thank you Again!
