- Bugscope Teamgood morning!
- Bugscope Teamwelcome to Bugscope!
- Bugscope Teamwe just finished the presets
- Bugscope TeamWe are ready to roll, and you may start driving as soon as you wish.
- 9:58 am
- TeacherWe just got in from recess, ready to go!
- Bugscope Teamgreat!
- Bugscope Teamplease let us know when you have questions
- Teacheris that the anntenea
- Bugscope Teamyes it is one of the antennae; one of them broke off
- Bugscope Teamyou can see the compound eyes on either side of the head
- Bugscope Teamthe flakelike things we see are scales
- Teacherhow many eyes are in a compound eye?
Bugscope Teamthere can be thousands, as in this one
- Bugscope Teama wasp can have 5000 individual ommatidia -- individual facets to the eye
- TeacherCan they see in color?
Bugscope Teamsome can and some cannot; some of the colors we see, they cannot see as well
- Bugscope Teamalso, many moths and some other insects can see ultraviolet wavelengths of light that we cannot see
- 10:03 am
- Bugscope Teamflowers may have ultraviolet colors
- Bugscope Teambe sure to click on one of the presets, to the left, when you want the 'scope to drive to another insect/arthrpod
- Bugscope Teamyou are driving a $600,000 microscope from your classroom
- TeacherDo all insects have compound eyes?
Bugscope Teamno -- some of them have simple eyes, and some of them have both
- Teacherwe can get the butterfly wing to come up
- Bugscope Teamfor example, wasps and bees and many other flying insects have compound eyes, of course, but they also have ocelli -- three simple eyes -- on the top of their heads
- Bugscope Teamthe ocelli help them keep oriented with respect to the sun, so they don't get lost
- TeacherI've clicked on butterfly wing and it says pending
- Bugscope Teamyeah it seems to be hanging up
- Bugscope TeamI will drive directly to it for you
- 10:09 am
- TeacherAre these the scales or are they feathers?
- Bugscope Teamthese are scales; they function a bit like feathers
- TeacherDo wings have holes in them?
- Bugscope Teamthe scales have tiny holes in them, yes
- Bugscope Teamscales give the wings color, and they also help if you happen to fly into a spider web
- Bugscope Teamthe scales will stick to the web, and come off, and you can slip out
- TeacherHow many scales are on each wing? We guessed millions.
Bugscope TeamI think you are close. I'm not sure anyone has counted.
- Bugscope Teamthe scales are what make the wings feel so silky to us
- Bugscope Teamplease let us help drive, since the software is acting funny this morning
- TeacherTrying to go to Probosic
- Bugscope Teamlet us know where you would like to go
- TeacherWhat are those?
- 10:14 am
- Bugscope Teamso we just drove past another mosquito, and now we are looking at the tip of the proboscis of a female mosquito
- Bugscope Teamthe proboscis is actually just a sheath for the sharp parts inside
- TeacherCan we see inside it?
Bugscope TeamI am sorry we cannot see inside today.
- Bugscope Teamlater if you'd like Scot can send you links to the sharp parts
- TeacherIs that the part that pokes you?
Bugscope Teamyes it is called the fascicle, and it has four super sharp blades, and a siphon tube that carries your blood one way and saliva the other
- Bugscope Teamlet us know where else you'd like to go!
- TeacherDoes it have hair or fuzz on it?
Bugscope Teamit has tiny microsetae -- very small hairlike features -- on it
- Bugscope Teamif we look further down the shaft we will see that mosquitoes have scales as well!
- TeacherWe want to see the fly head.
- TeacherIs that the eye?
- Bugscope Teamyes it is! it is a little bit dried and shriveled
- 10:20 am
- Bugscope Teamthe antennae are to the top
- Bugscope Teamthere is a pad part to the antenna and also a branched part called an arista
- TeacherWhat are the long hairy things?
Bugscope Teamthose are bristles that are mechanosensory
- Bugscope Teamthe bristles, which are also setae, go through the cuticle and attach to nerves beneath
- TeacherWhat does mechanosensory mean?
Bugscope Teamit means that the fly can sense touch with them, like a cat's whiskers
- TeacherWe would like to see the underside of the ant head.
- Bugscope Teaminsects have their skeleton on the outside, so it is like they are wearing armor
- Bugscope Teamthat was a caddisfly larva we went by
- TeacherDo ants have teeth?
Bugscope Teamno they have mandibles that are made of chitin, or cuticle, like our fingernails
- Bugscope Teambut some insects, like ants, have hardened mandible tips -- they may have zinc or calcium in them
- 10:25 am
- TeacherDo they grow longer?
Bugscope Teamusually once they are adults they do not grow anymore
- TeacherIs this inside the mouth?
Bugscope Teamyes, we're looking at the mouth parts up close
- Bugscope Teamsome insects, and other arthropods, will molt multiple times
- TeacherIs this a queen ant or just a regular ant?
Bugscope Teamthis is just a regular black ant
- Bugscope Teamwhen insects molt they can regain parts they might have lost
- TeacherWhat are tenent setae? Can we look at them?
Bugscope TeamTenent setae are like tiny sticky hairs that help insects stick onto things.
- Bugscope TeamWe are driving the scope there, give us a second
- Bugscope Teamthere we go!
- Bugscope Teamthis is a pad called a pulvillus that has lots of these tiny sticky hairs on it -- the tenent setae
- Bugscope Teamtenent like the Spanish word 'tener'
- Bugscope Teamso pretty!
- 10:30 am
- TeacherWhat insects have these?
- Bugscope Teamthe electron beam makes them move!
- TeacherDo Wasp have these? Where are they located?
Bugscope Teamwasps have them as well, and they are on the limbs, usually near the ends and sometimes between the claws
- TeacherCan we see the Mexican jumping bean trap door next?
- Bugscope Teamthis is one of the claws
- Bugscope Teamyou can see lots of scales that the moth lost when it left the bean
- TeacherWhat does it do?
Bugscope Teamthat is where the larva pupates and metamorphoses into a moth!
- Bugscope Teamactually the same pesky moth that keeps coming back when we try to go to another preset
- TeacherWe would like to see the ant doing a cannon ball.
- 10:35 am
- Bugscope Teamcannonball!
- TeacherDoes he have stripes?
Bugscope Teamyes! but it is a girl ant!
- Bugscope Teamlet's look at the stripes!
- Bugscope Teamthe stripes are tiny ridges that make the head more sturdy
- TeacherAre most insects that hairy?
Bugscope Teamyes! they are hairy because the hairs help them sense their environment
- Bugscope Teamsome of the hairs are chemosensory, some are mechanosensory, some are thermosensory, and some are sticky, like the tenent setae
- TeacherIs the hair poky or soft?
Bugscope Teamsome are very soft, and some are rigid -- they don't bend well
- Bugscope Teamsome of the tiniest hairs are not sensory -- they just form patterns
- TeacherCan we see the Japanese Beetle Palp next?
Bugscope Teamyes!
- 10:41 am
- Bugscope Teamthe palp have tiny chemo receptors that are like taste buds
- TeacherWht is that?
Bugscope Teamthis, now, is the palp, which is an accessory mouthpart
- TeacherGet closer.
- Bugscope Teampalps help insects manipulate and taste their food
- Bugscope Teamtiny tastebuds!
- TeacherOmmatidia next please.
- Bugscope Teamthis is a male mosquito and you can tell because he has really frilly antennae
- Bugscope Teamif you had compound eyes it would be very hard to buy sun glasses!
- TeacherHA HA
- Bugscope Teambut compound eyes allow you to see changes in the visual field very quickly when something is trying to grab you!
- TeacherIs that to attract a mate?
Bugscope Teamyes it helps, and the antennae also help the male find a female
- TeacherAre those eyes?
Bugscope Teamyes these are eyes!
- 10:46 am
- Bugscope Teameach ommatidium produces a tiny image, and all of the images together let the mosquito see around it very clearly
- TeacherAnything else that you'd like us to see? We are at the end of our attention span! :)
- Bugscope Teambecause there are so many eye facets, and they wrap around the head, the mosquito can see all around it
- Bugscope Teamwould you like to see the caddis fly?
- TeacherWow that would be useful for a teacher! Yes lets see the fly.
- Bugscope Teamthese live underwater
- Bugscope Teamthey are predators and eat other insects
- Bugscope Teamit's creepy!
- Bugscope Teamunder the water there are lots of things that stick to the caddisfly larva
- TeacherHow do they breathe?
Bugscope Teamthey have tiny gills we can show you
- Bugscope Teamthese are the gills
- Bugscope Teamand how they collect air
- TeacherWe think he is scary!
Bugscope Teamyes he is!
- TeacherHow big is he is real life?
Bugscope Teamseveral millimeters long, curled and tiny like the edge of your fingernail
- TeacherThank you very much for today. We liked what we saw and learned a lot too!
- 10:51 am
- Bugscope TeamThank you!
