- Bugscope Team we're waiting for the vacuum to get better
- Bugscope Team hello!
- Bugscope Team Greetings.
- Bugscope Team welcome to Busgcope!
- Teacher Hello This is our first time using bugscope
- Bugscope Team We're setting up some presets for you.
- Bugscope Team We're finding some interesting things for you.
- Teacher ok. We invited all of 4th grade and we may not need the full hour. Is that ok?
- Bugscope Team We're happy you decided to try it out.
- Bugscope Team That is quite OK! The more the merrier!
- Bugscope Team We're here to answer questions as they come up, so feel free to enter the student's questions (or have them type them in).
- Bugscope Team We'll let you know when we're done with the presets.
- Bugscope Team We're almost ready.
- Bugscope Team Since this is your first time, here's how to see the most things: click on the blue arrow pointing left to see some preset buttons. Just single-click on those presets to jump there.
- Bugscope Team we are ready to roll!
- Bugscope Team Once there, you can zoom out or in using the +/- buttons at the top, or move around by simply clicking once on a point in the image.
- Bugscope Team To more quickly, we recommond zooming out (using the - button by the word Magnification), then clicking.
- Bugscope Team You now control the scope.
- Bugscope Team please let us know when you have questions, and let us know if you have any problems driving
- Bugscope Team We are done setting presents.
- Bugscope Team You may be begin.
- Bugscope Team Remember, if you have any trouble, ask us here. If for some reason your web browser stops working, you can phone us at 217-265-8164.
- Bugscope Team this is a wasp, but we can only see two of its wings, and wasps, as well as bees, have four wings
- Bugscope Team this is the wasp's head
- Bugscope Team we can see its compound eyes, its antennae, we can barely see its mandibles, and we can see its ocelli, on top of its head -- the simple eyes
- Teacher ok we are all here
- Bugscope Team Great!
- Bugscope Team great!
- Bugscope Team this is a green wasp, but we cannot see the color; we're using electrons rather than light to collect the images
- Bugscope Team Since what I typed earlier may have scrolled off the screen while you were getting everyone there, use the blue left arrow to see our list of presets. You single-click on those to jump there. To zoom in or out, click on the red +/- at the top. To move, click on a point in the picture.
- Bugscope Team Scott just moved to the eye.
- Bugscope Team yes! this is the compound eye!
- Teacher student question: What are the holes around where the antenna enter the head?
Bugscope Team The holes are the "ball and socket joint" where the antenna attach and its movement is controlled.
- Bugscope Team compound eyes allow the wasp to see all around its head
- Bugscope Team another thing about compound eyes is that they allow the insect to see motion -- to see things that might be trying to eat it -- more quickly
- Teacher What are the bumpy things between the eyes?
Bugscope Team those are the facets of the eyes
- Bugscope Team they're called ommatidia
- Teacher Are those hairs coming our of the eye?
- Bugscope Team yes! the hairs are called setae (see-tee), and they are mechanosensory, like cat or rat whiskers
- Bugscope Team these are longer setae at the top of the head
- Bugscope Team this is cool, right here -- the little tiny things are bacteria!
- Teacher Oh we thought it was tiny particles of dust.
- Teacher Students would like you to drive there since you know the directions.
- Bugscope Team I'm sorry about the stinger, but I looked earlier and saw that it was no there
- Teacher Can we see the stinger on the wasp?
Bugscope Team Do you want to drive there or let Scott?
Bugscope Team we cannot see the stinger -- it is inside the body
Bugscope Team Oops. I thought you could. He'll drive down there for you now.
- Bugscope Team this is the tip of the abdomen, where the stinger usually is
- Bugscope Team speaking of eyesight...
- Bugscope Team here we have a crustaceaen with poor eyesight
- Bugscope Team plus one of its antennae is missing
- Bugscope Team crustacean, spelling, sorry...
- Teacher How good is their eyesite?
Bugscope Team In wasps and bees, their eyesight is in some ways better than ours: they can see colors we can't, such as ultraviolet (light beyond the darkest purple you can imagine).
Bugscope Team In other ways it isn't as good, which is why you see bumblebees often bumping into things.
Bugscope Team Here's a fun fact: flowers often have patterns on their petals that we cannot see but bees can. In some orchids, these make little "landing strips" to direct the bee into the source of nectar at the base of the flower.
- Teacher Do we know the name of this insect? Did it come from RES?
Bugscope Team Yes, you did!
Bugscope Team If you take the magnification down, you can see more of it.
- Teacher This is a beetle?
Bugscope Team This is the "roly-poly", also known as a "sow bug" or "wood louse".
- Bugscope Team yes as Daniel says, many flowers have patterns in UV light that we cannot see. Monarch butterflies are like that as well. When we look at males and females, we can tell from the thinner bands on the wings that we are looking at a male, but the wings look very much alike to us. In UV, however male and female monarchs look wayyyy different from each other
- Teacher How do we take magnification down?
Bugscope Team Click on the red "-" at the top, near the word "Magnification".
Bugscope Team Or... I guess Scott is doing it for you.
Bugscope Team There you go.
Bugscope Team If you click near its feet, you can see more of it.
- Bugscope Team good job driving!
- Bugscope Team Nice work on increasing the magnification! You can see where one of the antenna has broken off.
- Bugscope Team this is pretty cool
- Teacher This is really cool!!
- Bugscope Team it has a kind of sparse moustache, like Jonathan Waters
- Teacher Is that dark place between the antennae the mouth?
Bugscope Team the mouth is a little lower
Bugscope Team Can't quite see the mouth. You can see the little eye in the upper left corner.
- Bugscope Team we can see, also, why rol
- Teacher Haaaa
- Bugscope Team ypolies are called isopods
- Bugscope Team iso- means 'the same'
- Bugscope Team and pod means foot
- Bugscope Team so isopods have all the same shaped feet
- Bugscope Team they are said also to have gills on this side -- the ventral side, or underside
- Bugscope Team we can see its right eye, on the left
- Bugscope Team I can help, since I am sitting at the microscope.
- Bugscope Team if you increase the magnification now you will see the compound eye
- Bugscope Team some wasps, as well as dragonflies, can have as many as 30,000 ommatidia -- eye facets -- per eye
- Bugscope Team oh you sent us an ant as well -- can I go look for it?
- Bugscope Team this is so cool, and you sent it!
- Teacher Students want to know what a roly poly and wasp eat.
Bugscope Team The roly poly eats dead plants. That's why you often find them under rotting leaves and in rotting logs.
Bugscope Team My brother had a compost bin in his back yard. He'd fill it full of coffee grounds from Starbucks. One day when he opened it up, it was full of thousands of roly-polies! I think they really like coffee grounds. :)
Bugscope Team Some wasps eat other insects. They sting them and move them back to the hive for the young larva to eat. Some feed off nectar like bees. In the fall, yellow jackets can be a real problem because the queen has kicked them out of the hive and they need to find food. This is why they are a nuisance at picnics: they want some of your sugary soda!
- Teacher Is that our ant?
Bugscope Team yes it is! I almost forgot, and it is such a nice one!
- Bugscope Team it has serrated mandibles, like a steak knife
- Bugscope Team this ant has better eyesight than most; we can tell by the number of ommatidia
- Teacher Does the ant have as good eye site as the wasps?
Bugscope Team likely not
Bugscope Team It's hard to say for certain, but it is probably about the same or worse.
- Bugscope Team some ants live underground full time and don't even bother to have eyes
- Bugscope Team ants communicate using chemical signals, and they sense those signals using chemoreceptors in their antennae
- Bugscope Team they are very sensitive to chemical scents
- Bugscope Team a wasp has a rounder, larger compound eye, and it also has ocelli on top of the head -- it can usually see much better than an ant. flying insects in general will be able to see better than terrestrial insects
- Bugscope Team this ant is kind of a surprise; she has ocelli
- Bugscope Team almost all ants we see are females
- Bugscope Team ocelli are the tiny 'simple eyes' on top of the head
- Bugscope Team here we can see two of the three ocelli fairly well
- Teacher What is ocelli?
Bugscope Team As Scott said, they perform a function like eyes, but aren't fully formed like regular eyes.
Bugscope Team These are often used for sensing dark and light, more than they are for actually "seeing" things.
- Bugscope Team larval insects -- caterpillars -- sometimes have about 10 eyes, five on each side of the head, called stemmata
- Bugscope Team the stemmata look like this -- not very exciting
- Bugscope Team this is a wild-looking beetle
- Bugscope Team the reason we see so many hairs is because the hairs (we're supposed to called them setae) are sensory
- Bugscope Team insects have exoskeletons, which is like if we were wearing armor -- they have a hard shell
- Bugscope Team so they do not have skin like we do
- Bugscope Team because they do not have skin, with nerve endings in it, they need to sense their environment in a different manner, and they use the hairs for that.
- Teacher Why are there hairs on its back?
Bugscope Team In addition to what Scott wrote, I'll toss something in here as the "plant guy": flowers make use of those setae (hairs) to spread pollen around.
- Bugscope Team the ant's brain is kind of like a preprogrammed computer, but it also has the capacity to learn some things
- Teacher Does an ant have a brain?
Bugscope Team yes it does -- it is fairly simple, though
Bugscope Team Yup. They also have a type of a nervous system, but not nearly as well developed.
- Bugscope Team this is the top of a fruitfly's head
- Bugscope Team we can see its ocelli
- Bugscope Team this fruitfly's brain is about 350 microns wide, about 0.35 or one third of a millimeter
- Teacher What is the size of the brain?
Bugscope Team For an ant, it is going to be very small, easily less than half the volume of its head.
Bugscope Team Scott gave a size here - 350 microns - that's very small.
- Teacher Why do the call this a fruit fly?
Bugscope Team Because these small flies really like rotting fruit. If you want to grow some of your own, peel a banana and leave it sitting on a plate near an open window. You very likely will have fruit flies within a few days.
Bugscope Team Fruit flies will start out as small tiny white maggots, so you'll see lots of those at first.
Bugscope Team Then they'll "pupate" before turning into tiny flies.
Bugscope Team The flies only live for a short time - long enough to mate and lay eggs for the next generation.
- Bugscope Team since Daniel got married his wife does not let him grow fruitflies as often, in his house
- Bugscope Team he says he had some just a month ago...
- Bugscope Team some insects, as adults, live only a few hours, and some do not even have mouths, as adults
- Teacher How long can a fruit fly survive?
Bugscope Team The flies themselves often live for less than a week, some types only for a day!
Bugscope Team They grow very quickly, which is why they are so useful for science! You can grow your own from egg to adult in a matter of weeks.
Bugscope Team Fruit flies were what started us (people) down the road of understanding how we inherit traits from our parents.
Bugscope Team Fruit flies - like us - can have different color eyes. Some red, some brown, some white.
- Bugscope Team fruitflies, in comparison, have sponging mouthparts
- Teacher Can we see those cool mouth parts?
Bugscope Team let's see if we can find some sponging mouthparts
- Teacher Do some flies bite you and why?
Bugscope Team some flies actually drink blood, such as horseflies and deerflies
Bugscope Team they have really cool, wicked, cutting/slashing mouthparts
Bugscope Team Yes. Horseflies and deerflies are particularly bad about this. They want nutrients and blood.
Bugscope Team Some flies also regurgitate (vomit) acid onto their food to pre-digest it! They then slurp it up like a sour milkshake! Yum!
- Bugscope Team So far we haven't managed to find a mouthpart. We are still trying. May take a few minutes.
- Teacher Do fruit flies have tongues?
Bugscope Team fruit flies do not have tongues; they have bulbous mouthparts
- Teacher Oh that is so cool!
- Bugscope Team the thing we see now is the wasp's tongue, called a 'glossa'
- Bugscope Team we can see that the wasp has two mandibles, which is another word for jaws
- Bugscope Team the jaws open right and left, like a gate
- Teacher How do they suck the juice out of fruit?
Bugscope Team they squeeze saliva out of their sponging mouthparts, and then they use those same sponging mouthparts to suck up what the saliva dissolves
- Bugscope Team Thank you!
- Bugscope Team You sent some super nice things for us all to look at!
- Teacher RES 4th grade says thank you so much?
Bugscope Team You are very welcome!!!!!!!!!
- Bugscope Team We hope you will sign up again!
