- Bugscope Team setting up 'scope
- Bugscope Team Checking in :)
- Bugscope Team k just a sec
- Bugscope Team no problem
- Bugscope Team here's your tick
- Bugscope Team here's the 'TJ sensory pit'
- Bugscope Team :)
- Bugscope Team can you zoom out a bit more?
- Bugscope Team and here is the weird medallion on one of the sides (also found on the opposite side)
- Bugscope Team zoom out?
- Bugscope Team perfect
- Bugscope Team To be honest, I'm not sure what that is, but I have my book with me so I'll check it out
- Bugscope Team Looks like it's the spiracle plate
- Bugscope Team so it's like a bunch of spiracles in one area?
- Bugscope Team a compound spiracle? :)
- Bugscope Team lol sounds like it - I'm reading further into it
- Bugscope Team I hope the Josh type dude logs in today to see this.
- Bugscope Team Welcome to Bugscope!
- Bugscope Team room 9 has control of the 'scope now
- Teacher Can we zoom in on the eye? Can you tell us a little about it?
Bugscope Team you have control if you want
- Bugscope Team this is the head of a fruitfly
- Bugscope Team we can see one of its compound eyes very clearly
- Bugscope Team to the lower right we see one of its antennae
- Bugscope Team in the middle of the head, between the compound eyes, which have so many facets, we see the ocelli, which are simple eyes
- Teacher How can a fly see in all directions?
Bugscope Team using eyes like this, with many small lenses
Bugscope Team It can't actually see in all directions without moving its body/head, but it has a wider field of vision than we do.
- Bugscope Team Fun fact about fruit flies - Drosophila melanogaster is actually a vinegar fly not a fruit fly. They're commonly called fruit flies because they're found on rotting fruit - which produces vinegar (they're food source)
- Bugscope Team their* food source
- Teacher Is that the eye that we are looking at?
Bugscope Team It is their compound eye. each of the individual squares is an ommatidia, which are the facets that make up the compound eye
- Teacher What the life span of a fly like this is?
Bugscope Team 40 to 50 days total, including time spent as a larva and pupa
- Teacher Is this part of the exosceleton?
Bugscope Team yes it is -- these are the jaws (mandibles) of a super tiony ant
- Bugscope Team tiny
- Bugscope Team ant
- Teacher A student asks how do they turn their heads?
Bugscope Team that is why they have compound eyes, because with some insects it is not easy to turn their heads
Bugscope Team The only insect capable of really turning their head to the left and right would be a praying mantis
- Bugscope Team These are the mandibles of Strumigenys rostrata, a species of "plier ant" native to Illinois
- Teacher How many eyes does a fly have?
Bugscope Team they have two compound eyes, which can have hundreds of lenses, and they have three ocelli
- Bugscope Team the ocelli -- the simple eyes -- do not register features very well
- Bugscope Team ant plier ant is reclining on her back
- Teacher Is that a tongue inside the ants mouth?
Bugscope Team it has four feelers that are called palps
Bugscope Team the palps help them taste their food
- Teacher Do insects have a heart?
Bugscope Team not like we do
Bugscope Team they have an open circulatory system, so it is more like an oil pump inside a truck engine
- Teacher Can you tell us about the teeth of this ant?
Bugscope Team Yes I can! :)
Bugscope Team This species of ant is a specialist on tiny jumping insects called springtails. Because springtails are easily frightened and can jump quickly, these ants are highly specialized in both their morphology and behavior
Bugscope Team They can detect springtails within a few milimeters of their body, and when they detect one (usually by contact or smell, as they have very poor eyesight), they freeze, orient at an almost imperceptively slow speed towards the springtail, and open their mandibles to about 60 degrees. They then lock their mandibles in place and contract their mandibular closer muscles, storing up energy like spring. Once they get close enough, the springtail touches a set of trigger hairs inside their jaws, which releases the mandibles, kind of like a bear trap. the teeth help the ant mantain a strong grip on the springtail while they sting it to incapacitate it. once its knocked out they take it back to the colony to feed to their larvae.
- Bugscope Team this is a female mocquir
- Bugscope Team mosquito
- Bugscope Team the things that look like donuts are pedicels, the bases of the antennae
- Teacher On the mosquito what are the things by its eye?
Bugscope Team so we can see its wraparound compound eyes
Bugscope Team Are you refferring to the fuzzy stalks inside a deflated ball looking structure? those are the antennae
Bugscope Team now we see the proboscis and two palps
- Bugscope Team we are following the proboscis to its tip
- Bugscope Team this is where the tip of the fascicle is...
- Bugscope Team we don't have any fleas, but we have a tick
- Teacher Can we see the wings?
Bugscope Team let's see if we can...
Bugscope Team the wings!
Bugscope Team A mosquito's body is covered in scales. similar to the bodies of butterflies. The scales probably help them escape spider webs.
- Teacher I have a request to see a flea. Can you tell us what insects we have to see?
Bugscope Team we have a tick, a moth, a robber fly, a stinkbug, a stonefly larva...
- Bugscope Team here you can see little scales- the flakey things
- Teacher Are those hair on the wings?
Bugscope Team the fringe-y things we see are the scales, which butterflies, moths, and silverfish have as well
- Bugscope Team there's a haltere in the middle of the screen. it beats opposite the wings
Bugscope Team halteres are reduced hindwings that act very much like gyroscopes and help stabilize flies while they are in flight.
- Teacher How may types of flies are their?
Bugscope Team Flies are grouped into the Order Diptera - meaning 2 wings.
Bugscope Team There are multiple families within this order, but there are roughly 100,000 known species worldwide
- Teacher Do you have a roley poley bug? Do you know what the little white spots are on the roley poley bug underside?
Bugscope Team We do not have any in the microscope for this session. roley poley "bugs" are actually not even insects, but rather Isopods, a type of crustacean. they are more closely related to lobsters than insects.
Bugscope Team maybe you are seeing eggs or little larvae on them?
- Teacher Where do flies lay their eggs?
Bugscope Team Depends upon the fly.
Bugscope Team Fruit flies will (somewhat obviously) go for fruit. The larva (maggots) look like and are about the same size as a grain of rice.
Bugscope Team A wide variety of them lay eggs in decaying flesh.
Bugscope Team I think they mostly like to lay their eggs on tuna salad sandwiches.
Bugscope Team Trivia here: certain flowers rely on flies for pollination. Those flowers often release odors reminiscent of decaying corpses. Yum! (Don't give your date one of those for prom!)
- Teacher How far and what types of areas do flies travel?
Bugscope Team they are on every continent, I think, not sure about Antarctica
Bugscope Team mosquitos are a kind of fly. even their name means 'little flies': mosca ito
Bugscope Team haha but they are on Antarctica :) there are called Arctic Midges and they're wicked cool
- Teacher Can you show us the tick?
- Bugscope Team this is the capitulum -- the 'head' portion of the tick
- Teacher Can you tell us what we are seeing now?
- Bugscope Team There are wingless midges that live in the antarctic year round.
Bugscope Team TDOT!!!!! ARGH.
Bugscope Team :D
Bugscope Team That's what I get for confirming they were midges and not "flies" per se before posting!!!!!
Bugscope Team Tdot, you need a midge rap. You got somethin'?
Bugscope Team I don't know enough about midges to free style a midge rap
- Bugscope Team it burrows into the host with that sharp part
- Bugscope Team we can see the recurved spines on the hypostome, in the middle, that help it keep buried in your skin
- Bugscope Team the things on the sides of the capitulum are palps that fold down when the tick feeds
- Teacher Are there particular fruits that the flies lay eggs in?
Bugscope Team They love bananas and apples, the two fruit I now have in my house. :(
Bugscope Team There's an invasive fruit fly from China that infests small fruit, particularly raspberries and blackberries. My research plots were full of them. They are going to be a *serious* economic pest for these fruits, and will probably put a large number of berry growers out of business.
- Bugscope Team the tick is leaning against a log like a juvenile delinquent, but it is an adult, with eight legs
Bugscope Team The black legged tick is a delinquent...spreading disease
- Teacher Where do flying insect migrate?
Bugscope Team If you mean for winter, many of them don't. Quite a number of them simply die in the winter time.
Bugscope Team This is often the life cycle of many butterflies and moths: they hatch from eggs in early summer, feed on plants up to the fall, overwinter as pupae, hatch in the spring, breed, die. Kind of depressing.
- Bugscope Team this is kind of like a wrist watch, but on both forearms, that ticks have
Bugscope Team only instead of telling time, it tells apart different chemicals like carbon dioxide, which it the air we (and many other animals) breath out
- Bugscope Team breathe*
- Teacher Is the claw on a fruit fly the same as a mantice? Can we see that part?
Bugscope Team I'll drive there manually, just a sec
- Bugscope Team this is the fruitfly claw
- Bugscope Team it is quite different from the raptorial forearms of mantises
- Teacher Are their baby fruit flies? And how do flys eat?
Bugscope Team The baby fruit flies are actually larva. They look like little white caterpillars, the size and shape of white rice grains.
Bugscope Team The larva have mandibles and eat by mashing the food before slurping it up.
Bugscope Team nice comparison Daniel - if anyone has seen the Dreamworkds movie Flushed Away there is a little one line song in the movie "that's not rice it's maggots you're eating"
Bugscope Team Also if no one has seen Flushed Away, I highly recommend it - the movie great and has an awesome soundtrack
- Teacher What the hairs do?
Bugscope Team Some function as mechanoreceptors and allow the fly to have a sense of touch. The group of hairs below the two claws act like velcro and allow the fly to adhere to surfaces.
Bugscope Team the ones we see now with flat ends are the ones Josh is referring to that stick to surfaces
Bugscope Team some hairs are water sensing, some sense hot and cold, and some are touch or wind sensitive, as Josh said
Bugscope Team some sense chemicals by touch, and some sense chemicals in the air
Bugscope Team some hairs, actually called setae (see-tee), are scales
- Bugscope Team The previously mentioned arctic midge lives for 2 years as a larva but only about a week as an adult. if I remember correctly
- Teacher How long do flies live?
Bugscope Team a Mayfly adult may only live a few hours.
Bugscope Team some flies live for weeks
Bugscope Team Correction, a Mayfly is not actually a fly but is in its own order, the Ephemeroptera. There are flies with similar adult lifespans though
Bugscope Team Ephemeroptera means that it is ephemeral, including being a fly
- Teacher What are the life span of a flea?
Bugscope Team The average adult life span is 2-3 months.
Bugscope Team But it it doesn't have a host (some animal to feed off of) then they may only live a few days
- Bugscope Team fleas can live in carpet for many months and perhaps years before they are disturbed and hatch
- Teacher Thank you so much for your time and our barrage of questions. We appreciate it.
- Bugscope Team Fleas also have larva that look kind of like caterpillars. in case no one mentioned that yet
- Bugscope Team Thank you for connecting with us today!
- Bugscope Team It was awesome working with y'all today! I hope you learned a lot :)
- Bugscope Team Thanks for listening to my Plier ant spiel :) Hope you had fun!
- Bugscope Team Yay!
