• 5:01 pm

• TeacherHi. Had big meeting just got out and class starting. Kids will be on in 5 mins
• Bugscope Teamhello!
• Bugscope TeamWelcome back to Bugscope!
• Bugscope TeamHi!
• Bugscope TeamHi Joe!

• Bugscope TeamHey Scott!
• 5:07 pm
• Bugscope Teamcouple more things to find...

• TeacherOK, finally in the library and kids coming in. Facilities didn't set up tables so running around doing that

• Bugscope Teamit's no problem, take your time.

• Bugscope TeamHello Henry!
• 5:13 pm
• StudentHello!
• StudentHello
• Bugscope TeamHi!
• Bugscope TeamHello Everyone!
• Bugscope TeamPlease let us know when you have questions, about anything...
• StudentYes Sir!
• Bugscope Teamthis is a closeup of the grasshopper's compound eye
• Bugscope Teamthe little hexagons we see are the ommatidia
• StudentCool!
• StudentHi
  Bugscope TeamHi Peter!
• StudentHi
  Bugscope TeamHello Heecheol Moon!
• Studentlol

• StudentHi
• Studenthi
• StudentWHat are those flakes near the hexagons?
  Bugscope Teammaybe you can drive up closer to see
  Bugscope Teamwe are not sure -- some kind of juju, dried debris
• StudentMucho gusto
• Student:)
• StudentI am Andy Lee
  Bugscope TeamAwesome -- nice to meet you!
• StudentInteresting
• StudentHi!!
• StudentHi
• StudentThis is cool
• StudentHI
• Bugscope Teamthese are the hornet's mandibles
• StudentI can't believe the bugscope could do this
• Studentyou kidding me? of course
• StudentNice to meet you too
• Bugscope Teamsome of these critters are so big we can only see portions of them
• StudentThis is epic
• StudentThis is epic
• StudentHi
• StudentMuy interesante
• StudentIs this the tooth?
• Bugscope Teamyou are driving the scanning electron microscope from your school
• StudentWhat is that
• StudentWhat specifically is a mandible?
• StudentLook at the eyes
• Student:P

• StudentHi
• Studentwhy is one part sticking out?

• StudentIt has a little far
• StudentHow is the texture of the tooth?
• StudentIt looks like a beak of bird :)
• 5:18 pm
• StudentHI

• StudentIs these furs?

• StudentWhat is that?
  Bugscope Teamthese are the grasshopper's palps and other mouthparts
• Studentygub
• StudentMistake
• StudentWhy is the teeth or beak overlapping each other
  Bugscope Teamthey always do, or almost always; they open and close like a gate
• Studentthis looks like a brain
• StudentWhat are palls?

• Studentwhat is a palps?
• StudentIs that a leg?
  Bugscope Teamthose are palps, which are used to help convey the food to the mouth and also help taste it

• Studentare those hair?
  Bugscope Teamthe things that look like hair are setae

• StudentWhat is a setae?
• StudentWhere are we?

• StudentWhat are palps?
  Bugscope Teamthey're feelers, accessory mouthparts

• Studentwhere are we?
  Bugscope TeamWe're near the grasshopper's mouth parts

• StudentWhat is the bumpy thing that is on the skin

• StudentIs that a long things like fur?
• Studentwhat are the parts of the hairs

• StudentJunsung..
• Studentoh
• Studentoh

• StudentWhy are you joking about brian?
• Studentwhat\

• Studentyeah what is a setae
  Bugscope Teama seta is a sensory hair, or sometimes it's not sensory, I guess

• Studenteww..

• Studentoh
• Studentthe photos are blurry

• StudentWhy it has little far in mouth?
• StudentWhy it has little far in mouth?
• Studentwhere is the mouth?
• Studenthow come this is mouth part?

• Studentits better

• Studentwhere are we now?
• Bugscope Teaminsects do not have skin -- they have an exoskeleton that is like a shrimp shell, or like armor
• StudentThe leg?
• Studenthehe
• Studentare these cuts??

• Studentwe are on the antennae
• Bugscope Teamso they have setae that stick through the exoskeleton -- the armor -- to allow them to sense their environs
• Studentdoes seta sense the prey?

• Studenthenry
• Studentdoes seta sense the prey?
  Bugscope Teamyes they do in many ways
• StudentWhat is that part?
• 5:23 pm
• StudentAntennae
• Student하하
• TeacherPlease give Jay Lee control
• StudentWhy are these setae so sensitive?
  Bugscope Teamsome are chemosensory, some are thermosensory, some are mechanosensory
• StudentWhat are the furs on the antenna?
  Bugscope Teamthe furs are the setae, these help with sensory.

• StudentWhat part does the hair do? Does it help the grasshopper?
• Studentare the furs there to feel things?
  Bugscope Teamyes they are, exactly

• StudentHow many furs are there?

• StudentThese setae look sharp from here

• StudentThat is eye I think
• StudentIs that the eye?
• StudentThe Circuler shape is eye?
• StudentAre those eyes?

• Studentis that the brain
• StudentThere are a lot of eyes
• Studentthose look like eyes on the side

• StudentWow
• StudentWhat is the middle part?

• Studentwhat is the little thing sticking out of the mouth?

• Studentęww
• StudentWhat is that thing insie of the mouth?

• Studentinside

• StudentIs this eye?
• StudentWhat is the little sticking things sticing out of mouht?
• StudentEye has a hexagon
• StudentEye has a hexagon
• StudentWhat part does the hair do? Does it help the grasshopper?
  Bugscope TeamYea, some hairs, or setae, are chemosensory, for example, the ones on the palps most likely help the grasshopper taste, there are these hairs on its legs as well, and for certain species these sense when there is overcrowding, and this turns grasshoppers (usually solitary) into locusts (gregarious form).
• StudentAre those hairs covering the antenna part?

• Studentwhat is proprioception
  Bugscope Teamself sensing, like so the insect can sense when its arm is bent or hyperextended
• StudentIt is a hexagon
• StudentAre those the eyes..?
• StudentWhat is that?
• Studentthe eyes has scratches

• StudentHow many spectrums can a fly see?

• Studentthe leg is covering the eye...

• StudentWhy it's eyes have tessellation?
  Bugscope Teamthat is the best way to close-pack things that are essentially round in a 3D shape
• StudentI think it is used for various vision

• StudentWhy are the shapes hexagons?
• Studentdo thoae shapes in the eyes help the insects to see things?

• StudentWhy are the shapes on the eye hexagons?
  Bugscope Teamclosepacking of the lenses

• StudentCan the hoverfly see different kinds of color?
  Bugscope Teamsome insects see colors better than others, and some see colors that others do not see; some see in UV wavelengths, which we do not
• StudentWhat is this?

• Studentwhat are those dots or hole?
• StudentWhat is the middle part of the mouth? Is that a mouth to suck the horney?
• StudentI heard that they can see ultra violet is that correct?
  Bugscope Teamyes it is -- some insects can see UV light
• StudentIs that mouth?
• Studentwhat is the spider web looking thing?

• Studentwhy mouth is divided by 2 parts?

• StudentWhat does the hoverfly eat?
• StudentWhat are those in the mouth?
• 5:28 pm
• TeacherPlease give Yenah control, thank you
• StudentWhat is this? Tounge?
  Bugscope Teamyes it is covered with juju though
• StudentI guess the middle thing might be the nose..
• StudentWhat is this? part?
• StudentWhat is the spider web looking thing inside the mouth?
• StudentAre the things in his mouth some left overs of food?
• Student/ban frogandy
• StudentHow do they eat?
• Studentwhy mouth is divided by 2 parts?
  Bugscope Teamit is really hard to tell, but the tongue is in the center, and there are palps on either side we do not see

• Studentwhat is this?
• StudentAre those thorns?
• StudentWhat is this?
• StudentWhat is mold?
  Bugscope Teamfungus/mold -- what comes along to help start the decaying process
• StudentWhat is this?

• StudentCan they taste?
• StudentWhat is that?
• StudentWhat part of the mummies?
• StudentWhat does the hoverfly eat?
  Bugscope TeamThe hoverfly adult feeds on nectar, the larvae feed on feces, decaying materials, or other insects, depending on the species
• Studentmummie...
• Studentwowo
• StudentWhat are those things?
  Bugscope Teamthose are mechanosensors

• Studentare these still hair?
• Studentare these still hair?
• Studentwhat are mummies?
• Studentare these still hair?
• StudentWhat is this mummies
• StudentWhat is mechanosensors?

• StudentWhy are they over lapping?
• Studentwhat do these things do?
• StudentWhat is these furs do?
• StudentWhat are those things that look like hair?
• StudentAre these thorns?

• Studentwhat insect is this?
  Bugscope Teamthis is the hoverfly

• Studentwow.. what is this part?
• Studentlag
  Bugscope Teamsorry
• StudentWhat is mechanosensors?
  Bugscope Teamthey get feedback from the motion of the haltere
• TeacherHaha SEM, can you put that in middle school language
• StudentWhy are they so bumpy?
• StudentWhat are mummies?
• Studentwhat is bacterium?
• StudentWhere's the mummie located?
• StudentWhat do these things do?
• StudentWhy is the surface of these mysterious things not flat?
• StudentWHAT IS THIS?
• StudentWhat part is this?
• StudentWHAT PART OF THE MUMMIES?
• Studentuh...
• StudentHow do they clean themselves?
  Bugscope Teamthey use oral secretions, either directly applied, or using an appendage to reach where the mouth can't
• StudentWhat part is this?

• StudentWhat is this part?

• StudentWhat is this?
• StudentWhat does it do?
  Bugscope Teamthis is part of a long, weighted shaft called the haltere that beats with a motion oppositve that of the wings
• StudentWhat is this?
• StudentWhat are these hair looking things? are they still setae??
• 5:33 pm
• StudentWhat are these hair looking things? are they still setae??
• StudentWhy is this so hairy while in the other hand, the other parts don't?
• StudentWhat is this part and what does fur do on this part of hoverfly?
• StudentLook on the upper left part of the picture!
• StudentIs this sort of like a bug flight sensor?
• StudentDoes the closepacking improve the eyesights other than the other insects?
  Bugscope TeamThe number of facets an insect have is more likely related to when an insect is active. diurnal insects (day active) usually have larger facets, where as nocturnal (night active) ones usually have tighter packed ones
• StudentBG DCFBHJN
• TeacherPlease give control to Yenah please
  Bugscope Teamgot it!
• StudentS;;']\
• Student¿¿¿¿¿
• StudentMistake
• Studentwhat are you doing andy
• StudentWhat is that furry thing?
  Bugscope Teamthis is close to the fly's body, and we see lots of setae

• StudentWhat part is this?

• StudentTjank you SEM!!

• Student*thank*
• StudentWhat does this part of the bug do?
• StudentThis is super cool. Thank you >
• Studentwow the butterfly wing scales looks cool

• StudentAre they holes?
• Studentwhy it has a little holes in each line?
• StudentWhy does it have holes on the wing?

• StudentWhat are those holes?
  Bugscope Teamthose are part of the latticework of a single scale on the wing of a butterfly

• StudentAre the wings woven?? like knitting??
  Bugscope Teamnot really but they look like that, don't they?
• StudentWhy does it has holes on the wing??
• Studentwhy does this wing have scales????
• Studentlike bamboo...

• StudentWhat is mechanosensors?
  Bugscope Teammechanosensors are just sensory units that senses movement
• StudentWHy does it have holes?

• StudentWhy do we have holes on butterfly wings?
• StudentChristopher typed weird things with my computer. It was not me

• StudentWhy does it have holes on the wing?????
• Studentwhy are there big holes?
• StudentWing is divided by 2 parts
• StudentDoesn't whold distract them when they are flying?
  Bugscope Teammold? they don't have mold on them while they are still alive
• StudentWhat are those things that looks like a ripped tissue?
• StudentWhat are the other uses of the scale?
• StudentWhy does it have holes on the wing??
  Bugscope Teamthey make the scales lighter in weight
• Studentwhy are there holes on the wing?
• StudentDo the scales help the butterfly when it's flying?
• TeacherOops. Yenah got disconneted. Can you give control to Lynn Kim please?
  Bugscope TeamLynn Kim is now the Master

• Studentwow, what is this?
• StudentWhat is that thing inside the hole?
• StudentWhat are these holes?
• StudentWhat are those two things that look like airplane jets?

• 5:39 pm
• StudentWhat are those things insdie the hole??
• StudentWhat is the part that is inside of the holes?
• StudentAre these thorns?

• StudentWhy is there sharp things in the holes?

• StudentOh! Those dusts were the scale!

• StudentHow the scale works? (please answer)
  Bugscope Teamby falling off easily when the insects flies into a spiderweb; by refracting light in what are called structural colors; by producing pigmented colors; also by functioning much like feathers
• Studentwhat are these things that are in the hole?

• StudentSo those are the 'powder' that get off when we touch their wings?
  Bugscope Teamyes it is!
• StudentWhat bug is this?
• StudentWhat bug are we looking at?

• StudentWhat is the name of this bug ??
• TeacherWhich bug are we on?
• Studentwhat is a sensillae?
  Bugscope Teamfancy term for a sensing organ

• StudentWhat bug are we looking at?
  Bugscope Teamyou are close up on a hornet's antenna
• StudentWhat is this part?

• StudentDisconnected...
• Bugscope Teamthis now is a dragonfly wing
• Studentwhat is that thing?

• Studentwhat are these sharp things?
  Bugscope Teamthey are spines on the wing veins

• StudentWhy is the wing so thin?
• StudentWhat is this stick on the part of the dragonfly wing?
• Bugscope Teamplacoid means it is plate-like

• Studentis it a smooth surface with little bumps?
  Bugscope Teamyes it is
• Studentoh

• StudentWhy do they have the sharp things?
• StudentWhat is the scratch?
• StudentWhy to wings have veins? Are they like nerves to control the wing?
• StudentWhat are the lines?
• StudentWhat are the sharp things on the dragonfly wing?
  Bugscope Teamthose are spines that probably protect it and also keep it from getting completely flattened and sticking to a wet surface
• StudentWhat are those lines on the wing?

• StudentIs it dragonfly wing?
  Bugscope Teamyes
• StudentIs the shapes are irregular?
• StudentWhat are those holes?Is it ripped off part?
• StudentWhat are those line of the wing?

• Studentthis looks like a cracked leaf
• StudentWhat are those line of the wing?
• StudentIs that a crack on the wing?
• StudentRectangle shape?
• StudentWhat are those line of the wing?

• StudentWhat are those lines on the wing?
• StudentWhat are those line of the wing?
• StudentWhy are dragonfly wings shiny?

• StudentWhat are those line of the wing?

• StudentPlease answer to Peter..
• Studentwhy is it smooth when butterfly wings have holes?
  Bugscope Teamthis is a completely different type of wing; I think it is safe to say that is evolutionarily older
• 5:44 pm
• Studentel mystery
• StudentWhat are the vein like things on the wing?
• StudentWhat is that scratch?
• StudentPlease answer to Christopher.. He is really curious about these
• StudentWhy are they hexagon?
• Studentwho's .?

• StudentWhy are they hexagon?

• StudentIs there any pattern for wings?
• StudentWhat is that hole for?
  Bugscope Teamwhat hole is that?
  Bugscope Teamsorry we miss some of the Q's
  Bugscope Teammany of the Q's

• StudentThe Wings have scratches
  Bugscope Teamyes they do!
• StudentWhy are they hexagon?
• StudentWhat are those lines on the wing?
  Bugscope Teamthose are wing veins
• Studentwhat is the difference between the dragonfly's wing and the butterfly's wing?
  Bugscope Teamdragonfly wing doesn't have scales, and they are generally much more elongate going perpendicularly away from the insect's body
  Bugscope TeamButterfly's wings are also hooked together so that they fly with more of a fluttering style
  Bugscope Teamthe dragonfly is more able to control each wing than the butterfly is
• Studentv

• StudentWhy are they hexagon?
• StudentI mean the scratch
  Bugscope Teamsome of those are places where the wing is broken; it is very fragile

• StudentI think many people are asking the same questions
• StudentWhat are the lines made of?
  Bugscope Teamchitin
• Studentwhy are the hexagons or pentagons(?) so irregular?
• TeacherNo worries, Scot, I'm telling them you can't answer them all. I'm trying too :)

• StudentIt looks like bat
• StudentIs it mouth part or claw of the hornet?

• Studentare those two wholes eyes?

• StudentIs there a reason that there are only two claws?
• Studentwhat are the white sharp things?
• StudentCan hornets bite?

• StudentWhat is the sharp thing?
• StudentAre those teeth?
  Bugscope Teaminsects do not have teeth, but some of the features like the claws are hardened with calcium or zinc, for example
• StudentWhat are these two horn-looking things?
  Bugscope Teamthose are claws

• Studentclaws?

• Studenthow and when do they use their claes?
  Bugscope Teamthey use them quite like we use our hands
• StudentWhat are those fur?
• StudentWhat are those furs?

• StudentDo claws have a poison?
• Studentwhat are these hairy things?
  Bugscope Teamlots of setae
• Studentdoes every insect have fur?
• Studenton which body part is this ?

• TeacherPlease give Kate control of the scope, Scot
• Bugscope Teamsome of the setae, or microsetae, help with thermoregulation

• Studentcool!

• StudentAre they are scales?
• Bugscope Teamplease apologize to Yenah for me
• StudentWhy do these hornets need claws when it can fly?
  Bugscope Teamthe claws help them walk over different surfaces
• StudentIs this leg?
• Studentwhat are does scales on the antenna?
• Studentwhat is that big things looking like little fins?

• Studentand why don't some places don't have holes?
• StudentWhy does it have so much hair?
  Bugscope Teamit has a huge variety of purposes
• StudentWhat are those?
• StudentWhy does it have a little kind of particles on the antehnna?
• StudentIs that aclaw?

• StudentIt's sharp!

• StudentWhat are those little hexagons on the antennae?
  Bugscope Teamthose we part of the texture of the cuticle
• 5:49 pm

• StudentDoes it have poison in it?
  Bugscope Teamnot in the claws. the poison in the hornets are in the stinger, which comes out of the last segment of the abdomen (a modified ovipositor, or egg laying apparatus)

• StudentThanks :D
• StudentWhat does these claw's fur do?
  Bugscope Teamit helps the insect tell when it is touching something

• Bugscope Teamwhen I was Scot I accidentally wiped Yenah off the map
• StudentWhat are those long pointy fur-looking things?
• Bugscope Teamso I am SEM again
• Studentwhy are there holes

• StudentYaaaayyyy :)
  Bugscope Teamhaha

• StudentScott and Sme is same?

• Studentwhy is the claw so dry, or at least it looks like it.
• StudentWhat are those furs for?

• StudentEscuse me Sem, when does the grasshopper use its claws?
  Bugscope Teamit uses them to grasp; when it walks it holds them up out of the way; in the center of the claws is the arolium, which inflates to help hold onto things
• StudentIs that a joint?
• StudentTHERE'S HAIRS ON THE BALL

• Studentis that a mouth?
• StudentScot = Sem? Is this right?
  Bugscope Teamyes and also sj, but that is in my office
• StudentIt is like a cactus....
• StudentWhat is the little bug-looking part?

• StudentWhat are the furry things? It's very hairy
• Studentcool they also have joints?
• Studentwhat is that big bumps?
• StudentIs that a joint?
• StudentWhy so hairy?
• Studentwhat are...
• StudentWhat are those circles?
• StudentWhat is circular part?
• StudentWhat are those balls?
• Studentwhy are there bumpy things/
• Bugscope Teamit is a ball and socket joint
• StudentWhat are those bumps?
• Studentw
• StudentWhat are those bumps?
• StudentWhat are those bumps?
• StudentIs that eyes?
• StudentIs that eyes?

• StudentExcuse me sem, what is the little bump?

• StudentWhat are the pimple-like bumps?
  Bugscope Teamthose are ocelli -- simple eyes that help the hornet navigate
• Studentwhat are those bumps?
  Bugscope Teamocelli
• StudentWhat are the little bumps?
  Bugscope Teamocelli --simple eyes
• Studentwhat are those bumps?
  Bugscope Teamocelli
• Studentwhat is ocelli
• StudentWhat is ocelli?
• Studentoh

• StudentWhat is Ocelli?
  Bugscope Teamthey are also called simple eyes, and there are three of them
• StudentSo, is ocelli same as eye?
• Studenteye

• StudentWhat are the things on the eyes?

• 5:54 pm
• Studentwhen the antenna breaks, does it regrow?
• StudentDo some of these insects only have ocellis? Or do they have other pairs of eyes which help them to see things clearly?
• Studenthow come there are so many setae?
  Bugscope TeamI think they help the insect hold onto the air and also help keep its temperature -- its body temperature -- stable
• StudentThis eye also have hexagon shape
  Bugscope Teamyes it does!
• StudentDoes hornet has 5 eyes?
• StudentWhat are those dusts near to the eyes?
• TeacherPlease give control to Katie Lee
  Bugscope TeamKatie Lee is the Supreme Commander
• Studentwas that an antena joint
  Bugscope Teamyup
• Studentwhy are the legs and the eyes so close together?...
• StudentWhy do they have more than 1eye?

• StudentWhat is that?

• Studentpimples
• Studentwhat is that little bump?
• Studentwhat is that bubble looking thing?
• StudentDo hornets have more than 2 eyes
  Bugscope Teamthey have huge compound eyes with many facets, and they also have three ocelli
• Studentwhat are those pimple looking bumps?

• Studentare those bumps simple eyes aas well?
• StudentWhat are those next to the hairy part?
• StudentWhat are those bumps on the bumps? Are they like air bubbles?
• Studentwhat are those lumps? (those look like eggs :D)

• StudentWhy do they have a lot of hairs?
• StudentWhy there are bumps on the bumps?

• Studentwhat is that bubble looking thing?
• StudentIs it eggs?

• StudentWhy is there a lot of hair?
• Studentthe bumps look like a cell

• Studentdon't think so
• Studentwhat is that bubble looking thing?
• StudentWhat is the line for in the middle between the bumps and the fur?
• Studentwhat is that bubble looking thing?
• StudentAre there reasons that they have all these bumps on bumps?
• Studentit looks like a pimple on a pimple

• StudentWhat is ommatidia?
  Bugscope Teamthey are the individual units that make up the compound eyes
• Bugscope Teamoops I should have said flies
• StudentWhy is there bumps on bumps?
  Bugscope Teamthat is some kind of oil, John

• Studentwhat is the difference between setae and vestiture?

• Studentit looks like stale bread
• StudentWhat is this? Eyes?
  Bugscope Teamsorry I see we are now on one of the claws, with an arolium in the center

• Studentwhy are there oils on the bumps? Why do they need it?
• Studentwhat does arolium mean?
• StudentWhat is biofilm?

• StudentWhat is arolium?
  Bugscope Teamit is a sort of air bag

• Studentwhat is biofilm

• StudentWhat does those furs do?
• StudentAre those mold?
• Studenta thin, slimy film of bacteria that adheres to a surface.

• Studentare those fur or claws?
  Bugscope Teamthose are sensory setae, so 'fur'\
• Studentwhat is the difference between setae and vestiture?
  Bugscope Teamthe setae form the vestiture
• Studentit looks like islands
  Bugscope Teamyes it does!
• TeacherPlease give control to Calvin Seo please

• StudentIt's cool
• Studentwhat does the ommatidia do?
  Bugscope Teamthey work together to give the insect a somewhat resolved picture of the world around them.
  Bugscope Teamresolution isn't great though, as in order to achieve the resolution of the human eye, the compound eye on us would have to be about 1 meter in diameter(imagine that on a human..
• StudentWhat are those sharp things?
  Bugscope Teamthose are mechanosensory setae -- they are touch-sensitive
• Studentits glitching
• StudentWhat is that sharp things?
• 5:59 pm
• Bugscope TeamCalvin is now the Boss of the 'scope

• Studentwhat are those things that looks like dust?
  Bugscope TeamYenah they probably are dust.
• Studentare I mean
• StudentWhat is mandibles?
  Bugscope Teamthat is what the jaws are called; in people, the lower jaw is the mandible and the upper jaw is the maxilla
• Studentwe saw this before
  Bugscope Teamsorry; who's driving?
• StudentWhat is mandibles?
  Bugscope Teamthey are what the jaws are called; they open side to side like a gate, not like our jaws
• Studentthe jaw
• Studentwhy are there two calvins
• StudentCalvin Seo's the leader now
  Bugscope Teamexactically
• Studentwasn't this the hornet we saw before?
  Bugscope Teamyes it is
• Studentlet's look at antenna segment
• StudentThere are 4CALVINS
• TeacherCalvin is but he's having trouble going to the Antennae Segment
  Bugscope TeamI can drive us directly to it
• Studentcool
• StudentIt looks like a worm...
• Studentwhat is that worm looking thing?????
• StudentWhy are antennae always curved when it can be straight?
• Studentwhat are these circle things?
• StudentWow who's is it?
• StudentThe holes, what are its effects?
• Bugscope Teambut I am sitting at the scanning electron microscope (SEM)
• StudentHow come some places have hokes?
• StudentWhat is placoid sensillae and chemoreceptors?
• StudentWe're near the placoid chemoreceptors?
  Bugscope Teamyes we are!
• StudentHow come some places have hokes?
• Studentwhat is placoid sensillae/chemoreeceptors?
• TeacherHaha. We are trying to get to the Antennae Segments. We saw the chemosensors already
  Bugscope Teamthese are on the antennae, DaddyO

• StudentIt also have a holes in it. Why is it?
• Bugscope Teamthis is the moth antenna
• Studentwhat are placoid sensillae/chemoreeceptors? Jae-Minwhat is placoid sensillae/chemoreeceptors?
• Studentwhat is that particles on it?
• Studentwhat is placoid sensillae/chemoreeceptors?
  Bugscope Teamthey are what help the insect sense things like smells in the air, or pheromones'
• StudentWhat are those things covering the antenna?
  Bugscope Teamscales
• 6:05 pm
• StudentWhat are the placoid sensillae:
  Bugscope Teamthey are plate-like sensory surfaces that may be chemoreceptors
• StudentWhy are the scales in on the antennae
• Studentit is like footprint
  Bugscope Teamyes it is!
• Studentwhy are there lots of scales on one side, and less in the other?
  Bugscope Teamthey were most likely surrounding it, but have since fallen off
• TeacherPlease give Nate Kim control
  Bugscope Teamgot it!
• StudentWhat are those little dotts?

• StudentDo scales grow back again?
  Bugscope Teamno they do not; the insect does not molt and does not grow new scales
• Studentwowo

• Bugscope Teamthis is totally cool
• Studentwow!
• Studentwhat is that?
• Studentit is like quid
• Studentantena?
• StudentThis looks like jellyfish!
• StudentWhy is that fur so long?

• StudentWhat are these jellyfish looking things?
• StudentIt is like octopus or squid
• Studentwhat is that lines thing?
• Studentit looks like a jelly fish
• Studentthis looks like the tree in avatar
• StudentWhat is the furry things?

• Studentantena
• StudentIt looks like a tree.. what is this?
• Studentdo the fur grow back?
• StudentIt looks like a bamboo stick with hair...
• StudentDoes this design of antennas help?
• StudentWhy does it have long fur looking things
• Studentwhy are there strings dangling?

• TeacherWhich bug is this from?
  Bugscope Teamit was just sitting there; it is from a mosquito or something
• Studentwhy are there strings dangling?
• Studentwhy are there strings dangling?

• Studentwhat bug is this from?
• Studentwhy are there strings dangling?'

• Studentdo the fur grow back?\

• Studentwhy are there strings dangling?
• StudentWhat is that?
• Studentwhat is this thing from?
  Bugscope TeamI am not sure. It is very small, someone's antennae
• Studentif they take out the slaughts, don't the scales grow back?

• StudentWhat is that?
  Bugscope Teamit is an antenna, and likely from a boy-type insect

• StudentWhy are there cracks on the wing?

• Bugscope Teamoops 'can'
• StudentIt looks little bit similar with the dragonfly's wing
• StudentThe grasshopper wing looks a lot like the dragonfly wing?
• StudentA mosquito... Why does it look like it's moving?
  Bugscope Teamthe electron beam cna affect it because it is small

• StudentHow come some places in the wings have cracks?
  Bugscope Teamit's not the insect's fault; it is likely our rough handling after the insect died

• StudentWhat are those holes?
• StudentIs grasshopper's wing stronger then dragon fly's?
  Bugscope Teammaybe...
• StudentWhy does it look like a leaf?
• StudentThey look likes leaves...

• Studentlook like cabage
• TeacherPlease give control to Sun Jun please
  Bugscope Teamgot it. Kim means 'gold'

• StudentIs that a eye?
• StudentHow can you identigy the female and the male?
  Bugscope Teamthere are lots of ways, but sometimes you cannot from the outside
• Studentwhat is that hole in the middle?

• StudentExact hexagon
  Bugscope Teamyeah Cool huh?
• StudentHow do you identify if its a boy insect and a girl insect?
  Bugscope Teamthey have different sexual organs. many insects, dissection is necessary. there are also sometimes sexual dimorphisms that occur so you can tell with just looking at the outside.
• StudentWow

• StudentWhat are those dirts?
• Bugscope Teamwith flies, the females' eyes are often far apart, and those of the males are close together
• Studentthe eyes look so cool

• Studentyes
• StudentThere is a hole on the bottom right. what is that?
• Studentwhy hexagons?
• StudentThen we have to disect the bugs to find out its gender?

• Bugscope Teamwith moths and mosquitoes, the antennae are often more ornate on the males
• StudentWhat are small things stuck?
• StudentWhat kind of view do they see through these eyes?
• StudentThe tessellations are so neat and located just next to each other

• Studentif their eyes get dirty can they clean it?

• Studentwhy hexagons?

• Studentso if the grasshopper dead body stays for a long time, will the wing be cracked a lot?
  Bugscope Teamthe wings become dried and more fragile, but should stay intact unless something/someones breaks it.

• StudentWhy all the insects has the hexagons in their eyes
  Bugscope Teamsometimes they are not hexagonal, but often are; it is a natural shape for something that is essentially round but close-packed in a dome shape

• Student?Why are the eyes always hexagon
• Studentit looks so cool
• StudentWhy is there so many dust on eye?
  Bugscope Teamit's partly our fault since the insects are dead and cannot clean themselves with their arms
• StudentWhat are small things stuck on the eye? Is it dust?

• Studentcan grubs live inside the eye
• StudentWhat is that hole?
  Bugscope TeamI think it is a place that looks like a hole but is actually absorbing electrons
• TeacherPlease give control to Chaelin Park please
• Studentwhat are dimorphism?
  Bugscope Teamdifferences between the sexes based on morphology, size, or something else
• Studentdo those white things disturb the grasshoppers from seeing?
• StudentWhat is the hole? and the white thing?
  Bugscope Teamthe white thing is a sensory setae that lets the insect know when wind is going by or something is touching it
• 6:15 pm

• StudentExcuse me Joe, how do the bugs clean themselves?
  Bugscope Teamthey use some type of oral secretion to clean areas their mouths can reach, and use their legs to help reach areas the mouth cannot.
• Bugscope TeamChaelin should be able to drive now.
• StudentH

• StudentWhat are those little holes on the eyes, Joe?
• StudentAre bugs supposedly to be clean?
  Bugscope Teamyes they are. they are usually quite fastidious

• Studentthe balance of a organ
• StudentWhat is haltere?
  Bugscope Teamit is a knobbed branchlike structure that beats opposite the way the wings beat (in flies) and balances that motion

• StudentWhat are those furs' functions?
• StudentWhat does haltere do?

• Studenthow does the hoverfly use its halatrae?
• Studentwhat's a haltere?
  Bugscope Teamhaltere is the modified second pair of wings in flies, the act as a sort of gyroscope used for balance in flight
• StudentIs it broken at the end?
  Bugscope Teamit is dried and shrunken, not like it is when the fly is alove
• Studentwhere's the haltere located?
  Bugscope Teamthey are where the hindwings would be

• Bugscope Teamor you could say they are modified hindwings
• Bugscope Teamthis is awesome
  Bugscope Teamyea crazy looking
• Studentthe balancing organ of a two-winged fly
  Bugscope Teamexactically!
• StudentAre those things are setae?
  Bugscope Teammicrosetae

• TeacherBeautiful!
• Bugscope Teamsometimes they are also called trichae

• TeacherI didn't even know about haltere before today. Amazing!

• StudentWhy is there thorn on the line?
• StudentA lot of setae! Do big amounts of setae do good for the bugs?
  Bugscope Teamthese form patterns, among other things; they may produce iridescence
• 6:20 pm
• StudentWhat is a trichae?
  Bugscope Teamit is another word entomolgists use for super tiny hair-like things
• StudentAre there sometimes setae on the insects' wings?
• StudentWhat are iridescence?
  Bugscope Teamreflecting light in shiny colors
• StudentSEM and Scot thank you!!
  Bugscope TeamThank You!
• StudentThank you
• StudentThank you!!
• StudentThank you~
• StudentThank you and bye
• StudentThank you!
• StudentTHANK YOU~~~
• StudentThank you!
• StudentThaaannnkksssss!
• TeacherSome students are leaving but I have about 10 more minutes
• StudentThank you....bye....
• StudentThank you!
• Studentthank you ~~!!^.^
• Bugscope TeamJoe is an entomologist, so he keeps me in line.
• StudentThank you so much! :)
• StudentBye~!!!
• Bugscope TeamThanks1 bye!
• TeacherPlease give me control
  Bugscope Teamgot it DaddyO
• StudentThank you! I got to learn more about bugs :D Bye!
  Bugscope TeamBye Sue!
• TeacherI want to snap a few more pics for our collection

• Bugscope TeamThank You, Everyone!

• Studentthank you
  Bugscope TeamThank You, John!

• Bugscope Teamyou can see the retention plan

• Bugscope Teamthe big spines on those raptorial forelimbs

• Bugscope Teamthis is the arolium, in the center
• Bugscope Teamit puffs up and helps the insect hold onto crevices

• Teacheri
• TeacherWow, it's flexible
  Bugscope Teamprobably puffs up with hemolymph
• 6:25 pm
• TeacherYes, hemolymph. Cool adaptation
• TeacherOops, I have a student here who wants to take control a little, David please.
  Bugscope TeamGot it!

• Bugscope Teammore spinelike setae, on the hornet leg

• Bugscope Teamtiny crystals of some sort
• TeacherThe microstructure on these is intense
  Bugscope Teamyes it is. pretty cool

• Bugscope Teamgood job driving

• TeacherAre the grooves for increasing sensitivity?
  Bugscope TeamI think they make the spines much stronger, less apt to bend

• TeacherAah that makes sense

• Bugscope TeamDude I am not sure what all of these bristles do, but they seem protective

• 6:30 pm

• Bugscope Teamnow we are at a disadvantage because the microscope is set up at a long working distance

• Bugscope Teamthe long working distance allows us to see more at lower mag but gives us worse resolution at high mag

• Bugscope Teamif everything was at a short working distance we would resolve better now but we would not be able to see much of the insects when we're backed out
• Studentit's so Cool!

• StudentI learned a lot today. Thank you so much!
  Bugscope Teamhey good job driving, David
• TeacherDavid has to go can you give me control one more time
• Bugscope Teamwe are more than an inch from the pole piece
• Bugscope Teamhard to see here, though
• Bugscope Teamthis is the inside of the chamber, but the camera is dying
• Bugscope Teamnow we're using the secondary electron detector again
• StudentBBye!
• TeacherJust wanted to see this butterfly antennae once more
  Bugscope Teamokay we can go to that
• Student:D
• StudentThank you everyone~~
  Bugscope TeamThank You!
• TeacherCheers
• TeacherSo they really have scales on their antennae?\
  Bugscope Teambutterflies, moths, skippers, mosquitoes
• Bugscope Teamand silverfish
• 6:37 pm
• Teachercool. No worries about the magnification. The kids lose perspective when we are in too close.
• TeacherThanks for staying late guys. I know the time difference is tough. I really appreciate it
• TeacherGotta go get ready for my other lessons today. I'll ssee you all tomorrow. Now room is ready and I won't have a cross pacific meeting to go to in the morning
• TeacherTake care and have a good night
• 6:43 pm
• Bugscope TeamThank you -- sorry I got caught in a conversation with a lab denizen.
• Bugscope Teamsee you tomorrow
