- Bugscope Team waiting for vacuum
- Bugscope Team this is the inside of the vacuum chamber
- Guest TESTING.. ARE WE ACTIVE?
- Guest Just FYI, We'll have one computer in each of the three classrooms signed on and sending questions your way.
- Bugscope Team yes we are active sorry did not see your message right away
- Teacher this is class two of three. Getting us logged in.
- Teacher we're ok to have three computers logged in, correct?
- Bugscope Team you can have as many as maybe 25 or 30. but only one person can drive at once
- Guest sounds good. I'll be in my own classroom so you may need to do a brief intro as to how to drive.
- Guest so these are the three classes below.
- Bugscope Team cool we are ready to roll
- Bugscope Team you can test if you would like
- Bugscope Team from Wikipedia:
- Bugscope Team This species has evolved a very interesting relationship with the yeast-like fungus, Endomyces hylecoeti. Every egg the female lays is coated with fungal spores from a pouch near her ovipositor. The larvae hatch and collect some of the spores by staying close to their egg shells for a while before tunnelling into the wood. The fungi grows on the walls of the tunnel the larvae make and it is this the young eat rather than the wood. The fungi requires a good flow of air, so the larvae keep their tunnel free of any debris.
- Bugscope Team this is a ship timber beetle
- Bugscope Team insects and similar athropods often have what appear to be too many hairs (setae) to count
- Teacher We're here and about ready to start. we have our first question which is how many hairs are on this type of beatle.
Bugscope Team lots and lots. many insects have hairs all over their body. These hairs are called setae, and they allow the insect to sense its environment and itself.
Bugscope Team These are necessary as insects have an exoskeleton, meaning they have a hard shell which they can't sense through. setae can also aid in thermoregulation
- Guest What are the parts that look like hands and have 10 or 12 fingers?
Bugscope Team those are palps, which are modified in this species, or highly modified in this species\
- Bugscope Team palps are accessory mouthparts that usually help insects taste and manipulate their food into their mouths
- Guest Thank you
- Guest What are they used for?
Bugscope Team this is a male ship timber beetle, and those weird palps are said to help the male hold onto the female
- Guest d
- Teacher how any eggs can this beetle lay?
Bugscope Team I'm not sure anyone knows. Likely dozens to hundreds.
- Bugscope Team Mr D has control of the microscope. If another classroom would like to drive we can give them access.
- Guest Does his antennae come from some sort of hole? Does he have 2?
Bugscope Team All insects have 2 antennae. it is in a joint socket so that the antennae can move freely.
- Bugscope Team in the center of the view we see now -- of a female mosquito, the central component is the proboscis\
- Guest Is that the antennae in the middle?
Bugscope Team the thing in the very middle is the proboscis- the mouth part. you can see part of one antennae coming from the middle of the screen and going to the upper right
- Teacher What are the dots all over the body?
Bugscope Team those dots are the individual facets of the mosquito's compound eyes
- Guest Why does it look like a pinecone on the bottom? Of the mosquito!
Bugscope Team i think we are looking at the proboscis of the mosquito. mosquitoes are covered in modified setae called scales. these kind of make it look like a pinecone. the large areas to the side of the center tube are the eyes.
- Guest Do we know how many facets there are? WOW!
Bugscope Team there are likely a few thousand. some large wasps can have 30,000 ommatidia per eye
- Guest Cool close ups of the eye!
Bugscope Team we can see that they are slightly shrunken, dried out a bit from the way they were when the mosquito was alive]
- Teacher Does each facet represent a human type eye?
Bugscope Team the individual ommatidia are not as good as human eyes, generally
- Guest How does a mosquito hear?
Bugscope Team the antennae of a male mosquito have components that can sense the beat frequency of a female's wings; the component is called a Johnson's organ, and other insects may have them as well
- Guest Do insects have DNA?
Bugscope Team yes they do!
- Bugscope Team here the mandibles are in the upper middle of the face
- Bugscope Team they open out like a gate, unlike our jaws, which go up and down
- Teacher I have 2 questions: do bugs have teeth, and do beetles live in colonies?
Bugscope Team bugs do not have teeth but they can have hardened mandibles
Bugscope Team they don't have teeth, but they do have mandibles that are very similar in function.
Bugscope Team some beetles do live in colonies
Bugscope Team these are the ambrosia beetles, there is a species that have a similar caste structure that we see in honey bees. Reproductive female with worker females.
- Guest What is a borer?
Bugscope Team in this case borer is referring to wood borer, they bore holes into wood materials and some feed on the wood, and others may cultivate fungus in the tunnels created and feed on that.
- Teacher can you show us a mandible?
Bugscope Team the smooth things we see now are this borer's mandibles
- Guest What does a mosquito bite you with?
Bugscope Team female mosquitoes bite, and they do that using a muscular mouthpart called a fascicle that has four cutting components in it as well as a siphon tube and another part I am not sure about
Bugscope Team the bite is more similar to a needle injection
- Bugscope Team the fascicle comes out of the proboscis, which is like a sheath
- Guest Yikes!! We dont like needles.
Bugscope Team you can hardly feel it
- Guest We feel the itch though
- Guest Why does it make you itch?
Bugscope Team we think it is because we have a reaction to the mosquito's saliva, which comes through another small vein in the siphon tube and keeps our blood from clotting
- Guest What is the hairy stuff surrounding the mandibles?
Bugscope Team a lot of those are indeed bug hairs, which we call setae. They help the beetle to sense what is going on around it, usually for sense of touch.
- Teacher Can you explain the beetle diet?
Bugscope Team beetles are opportunists and also a super huge group or family of insects; so they eat all kinds of stuff depending on what kind of beetle they are
- Bugscope Team the ship timber beetles do not eat wood; they feed on a fungus that the female adult has in a pouch near her ovipositor so that it gets attached to the eggs as they are laid\
- Teacher What is this?
Bugscope Team this is a claw -- one of the borer's claws
- Guest Is there a pad that helps him hold on like an ant?
Bugscope Team great question! this one does not seem to have that pad, which is called a pulvillus and is covered with tenent setae
- Guest What are the spikes on the legs for?
Bugscope Team they are mechanosensory setae responsible for sense of touch
- Teacher Where do moscetos live?
Bugscope Team they like wet places like streams, ponds, marshes usually because that is where they lay their eggs
Bugscope Team some of them like standing water, so buckets of water that's been left out, or clogged gutters are also areas where mosquitoes can breed
- Guest Does it have three moving parts in it's claw?
Bugscope Team some claws move and some do not. with the ones that move -- open and close -- there is an internal tendon-like thing called an unguitractor that helps make that happen
- Guest do they have segmented legs?
Bugscope Team yes they do! here we see only a few segments
- Guest Does it have hairs coming out of it?
Bugscope Team yes those are used mostly for touch-sensing; they are mechanosensory
- Guest Why does the borer claw look like a pick ax? Looks like
Bugscope Team that is probably its relaxed or actually maybe the opposite, its constricted shape. we were impressed that it looks like it has serrations on the inner sides
- Bugscope Team so cute! a baby ladybug
- Teacher the legs look hollow, are they?
Bugscope Team they are filled with nerves and muscles bathed in hemolymph
- Guest not so cute!
Bugscope Team they are predators and like to eat aphids, in particular
- Guest Cute if your his momma!
- Teacher are their eyes?
Bugscope Team they have simple eyes as larvae. they look like round bumps on the sides of their head
- Bugscope Team sometimes we find them covered with aphid bodies, like they've taken trophies
- Guest haha E1
- Guest What are the spikes on his back almost like a stegasaurus>?
- Teacher what are the spikes on the back for?
Bugscope Team likely they help keep them from being easily eaten -- they're spines
- Guest Is the stemmata the eye?
Bugscope Team yes!
Bugscope Team we can see at least two. the thing to the right and down is the antenna, which is fairly rudimentary, like the stemmata
- Guest Does he have wings?
Bugscope Team no. only adult insects (of all types) have wings
- Guest Is it the knobby looking thing?
Bugscope Team that is one of the antennae
- Guest We say EWWWWWW!
Bugscope Team haha
- Teacher Why does a lady bug have spots?
Bugscope Team they have their bright red spots to warn other animals not to eat it. they dont taste/smell very good
- Guest Does it look for food right when it comes out of the egg?
Bugscope Team pretty much. they may have a period in which they breathe, inflate a bit, and harden in the air
- Guest Where is the eye?
Bugscope Team there are at least two but they are hard to distinguish. one is above center and to the left.
- Teacher we are interested in what this is?
- Guest What is the part that looks like spaghetti?
- Guest Why do they call boy lady bugs "lady bugs?"
Bugscope Team It's in reference to Mary, mother of Jesus, and in Britain, they became known as Our lady's beetle. The proper colloquial name for ladybugs is ladybird beetle, or lady beetle.
- Guest We are amazed that it is only as wide as one hair.
- Guest what is a flying spaghetti monster?!!!!
Bugscope Team FSM. those are not really flyting spaghety
- Guest Thank you for your excellent answer about lady bugs.
- Bugscope Team boys have spots
- Guest Do all insects have segmented legs?
Bugscope Team yup.
Bugscope Team all arthropods in fact. crabs, spiders, scorpions. arthropods mean jointed legs
- Guest Can we see a FSM leg?
Bugscope Team they're called noodly appendages
- Guest back to ladybugs, do boys not have spots?
Bugscope Team they do, in general, males look largely similar to females. there are species where the males don't look like females, and not all ladybird beetles have spots.
- Teacher can you tell us about this type of insect?
- Teacher What do FSM's eat?
- Guest Looking quite "noodly" Gluten free?
Bugscope Team haha not sure
- Bugscope Team they are actually.,
- Guest Oh good!
- Bugscope Team we think they are a kind of plant spore-like body that flies through the air
- Bugscope Team they get picked up by wind currents
- Guest Why is it called a spaghetti monster? Do they have wings?
Bugscope Team they are called spaghetti monsr\t
- Bugscope Team sorry totallyt \
- Guest How many legs do they have?
Bugscope Team insects all have 6 legs. arachnids (spiders, ticks, scorpions) have 8 (some juveniles with 6).
- Bugscope Team cannot type
- Bugscope Team spaghetti monst
- Bugscope Team still cannot type
- Guest no worries!
Bugscope Team this is a ladybug's compound eye
- Guest The 12 fingers body part?
Bugscope Team that was a palp on the ship timber beetle
- Guest My bad, sorry
- Guest Isn't a palp the part they eat with?
Bugscope Team yes usually
- Bugscope Team palps are like forks and spoons that can taste your food for you before you eat it
- Guest Are those sensory spikes?
- Bugscope Team but some have other purposes
- Guest Can we see the ant claw before our time is over?
- Bugscope Team Cate thinks this is mineral and not pollen. She may be correct.
- Bugscope Team pollen can look different depending on the plant it came from. ragweed looks like spiky balls
- Bugscope Team lily pollen grains look like deflated footballs
- Bugscope Team the spiky ragweed pollen grains, you can imagine, would be great for getting on clothing or fur so it can move to other places with ease
- Guest You read our minds! These look like intricate ladders.
- Bugscope Team essential...
- Bugscope Team if we had no bees at all a lot of the fruit we eat would not exist
- Teacher can you tell us about these and how they get the color?
Bugscope Team scales can have colour granules ingrained which is partially responsible for some of the colours (i think orange might be in this category). Other colours are created with the way light reflects and refracts off the microstructures of the scales.
- Guest Why are there holes in the butterflies wings?
Bugscope Team the holes make the wing scales much lighter; likely they also help hold air; they are analogous to feathers in some ways
- Bugscope Team scales also have a purpose in protecting butterflies, moths, skippers, silverfish, and mosquitoes from spider webs
- Guest Travel or fly?
- Guest Are scales different sizes in different insects wings?
Bugscope Team there are scales of different size on just one insect. They can sometimes be long and skinny, and sometimes more like a potato chip like here
Bugscope Team they are the insect's version of hairs
- Teacher how are buttrtflies eyes work compared to human eyes? do they see well?
Bugscope Team they see very well, but differently from humans. they have many ommatidia, or facets, in their eyes that allow them to see movement better than we can
Bugscope Team better movement detection, worse resolution
- Guest How fast can butterflies travel?
Bugscope Team it varies by the butterfly; I think it takes a few months for Monarchs to fly hundreds of miles to Mexico. they probably take advantage of wind currents as well, so it is traveling
- Guest Thank you~~
- Guest Where is the sticky pad?
Bugscope Team this may not have a sticky pad; instead it may have what is called an arolium
- Guest What are the two swords on the side used for?
Bugscope Team they are used kind of the same way we use our fingers, or our hands
- Bugscope Team the swords are the claws
- Teacher are their bodies covered in this?
Bugscope Team only if they have become gunked up with bacteria, and likely then after they died
- Guest Why does it look like spider webs?
Bugscope Team the parts that did not dry out look like that; the more jelly-like fluid is gone
- Guest What is biofilm
Bugscope Team bioflim is secreted by bacteria; it protects the bacteria, which can swim around in it
Bugscope Team oops biofilm
- Teacher Do the ant satae work like the other insect satea?
Bugscope Team mostly, setae are shaped mostly by function.
- Bugscope Team biofilm can be dangerous to humans because it can protect bad bacteria from getting washed off or fruits and vegetables
- Bugscope Team thanks for joining us today for bugscope
- Teacher Thats a rap! Thank you so much for showing us this great information. We loved it!!
Bugscope Team Thank you, Mr D!
