• 8:57 am
• Bugscope Teamsession enabled, rxl started
• Bugscope Teamhey DaddyO
• Bugscope Teamhi there
• 9:09 am
• Bugscope Teamventing scope, removing a juicy bug
• 9:16 am
• Bugscope Teamstarting vac again
• Bugscope Teammite!
• Bugscope Teama few minutes ago we got a message about leaks in the pneumatic system on the 1st and 2nd floor. it is possible those could bring us down -- something to watch out for.

• 9:22 am

• 9:29 am

• 9:36 am

• Bugscope TeamAt 3 your time -- 3 to 5 p.m.

• 9:41 am

• Bugscope TeamAbescope

• 9:48 am
• Bugscope Teampresets are done

• 9:53 am

• 9:58 am

• Bugscope Teamhi kristin, welcome to bugscope!

• Teacherwhat are we looking at

• Bugscope Teamthis is a beetle
• Bugscope Teamhey there welcome. If you have any questions let us know.
• Bugscope TeamYou can start by clicking on a preset in the lower right if you like
• Bugscope Teamright in the center here you see a pattern of hexagons, and that is the eye

• Bugscope Teamthis is right next to the eye, there, to the left
• Bugscope Teamthis is a clubbed-end antenna
• Bugscope Teamon a small beetle
• Teacherwhy do flys fly around you when you are hot
• Teacherwhat does the antenna do?
• Bugscope Teambecause, possibly, you smell particularly good to them at that time

• Bugscope Teammaybe flys are attracted to the smell that humans give off when they perspire?
• Bugscope Teamthe antenna collects pheromones, for one thing, from the air
• Bugscope Teamit is sensitive to chemical signals
• Bugscope Teamthis is the head of an ant, and one of its antennae is missing
• Teacheris the eye on the top middle
• Bugscope Teamwe are looking right into the mouth here
• Bugscope Teamfor ants, they leave behind chemical signals to let others know where food is, or where an enemy is
• 10:03 am
• Bugscope Teamthere is a eye on the left top
• Bugscope Teama mound shape
• Teacherhow much can a single ant carrie
• Bugscope Teamwith facets in it
• Bugscope Teamthe top middle is where an antenna broke off
• Bugscope TeamIt can lift 50x its weight
• Bugscope Teamsome of them can carry more than their own body weight
• Bugscope TeamI don't know how much that equals to
• Bugscope Teamas Cate says, much more

• Teachercan you tell us more about this
• Bugscope Teamthis is pretty cool
• Bugscope Teamthese are the little sitcky 'hairs' that help some insects stick to vertical walls or ceilings
• Bugscope Teamsticky
• Teacherso is this what spiderman crawls with
  Bugscope Teamexactly
• Bugscope Teamif you take the mag down here you can see where you are
• Bugscope Teamyou can see where these are found on the tarsus
• Bugscope Teamin the first movie, you see how he grows little hairs in his fingers and then he crawls up a wall, that is the same principle
• Teacherwhy do snails die when you pour salt on them
• Bugscope Teamthe tarsi are the segments of the arm or leg closest to the claw

• Bugscope TeamI imagine that the salts cause the snail to lose liquid -- to lose water that they are made of

• Teachertell us more about this picture
• Bugscope Teamit has the effect of drying the snail out very rapidly
• Teacherwhat are the bubbles in his mouth
• 10:09 am
• Bugscope Teamthis is the tip of a palp of a beetle
• Teacherwhat is a palp
• Bugscope Teampalps let the beetle taste its food
• Bugscope Teamthe palps are like little feelers that help the beetle taste and manipulate its food
• Bugscope Teamthe bubblelike things are taste buds
• Teacheris there any food on the beetle
• Bugscope Teamthat let the beetle smell its prospective food
• Bugscope Teamcould be if you take the mag down to see
• Teacherwhat does its nose look like
• Teacherwhat are grass beetles
• Bugscope Teamthese are not stored images -- you are actually driving a scanning electron microscope
• Bugscope TeamInsects smell with their antennae and they breathe through holes on their thorax and abdomen
• Bugscope Teamso you can take the mag down by clicking minus in the Magnify box.

• Bugscope Teamcool!
• Bugscope TeamThey have two different body parts to do what our nose does.

• Bugscope Teamwhen you click to drive remember to click to stop

• Bugscope Teamand you can take the mag lower to see where you are
• Bugscope Teamteacher, if you get lost, you can always click on a preset and the scope will move to that location
• Bugscope Teamthis is pretty high mag now

• Bugscope Teamhey cool
• Bugscope Teamthis is the claw of a true bug
• Bugscope Teamtrue bugs are a particular kind of insect
• Teacherwhat bug is tit
  Bugscope Teamthis is some sort of true bug
• Teacherit
• Bugscope Teamthat has, for example, piercing mouthparts
• 10:14 am
• Bugscope Teamif you take the magnification down you should be able to see its body
• Teacherhow hard does it pinch
  Bugscope TeamTrue bugs have sucking mouthparts, so they can't pinch when they bite. When true bugs bite, they stick you
• Bugscope Teamhemiptera

• Bugscope Teamit means 'half wing' and indicates (Annie can correct me) that the wings are partially covered by the elytra -- the shell that some insects have covering their wings

• Bugscope Teamyou are getting better and better at driving -- it is not so easy

• Bugscope Teamhere it is interesting to see that there seems to be a pad of tenent setae on the end of this joint

• Bugscope Teamthis is the head of a moth
• Bugscope Teamthe defining feature of true bugs is their possession of mouthparts where the mandibles and maxillae have evolved into a proboscis - (from wikipedia)
• Teacherwhat is this
• Teacherdo moths have fur
• Bugscope Teamyou can see the big round eyes on either side of the bright scaled portions
• Bugscope Teammoths do look furry
• Teacherwhat do beetles eat
  Bugscope Teamthe lady bug eats other insects
  Bugscope TeamBeetles eat almost anything imaginable: pollen, wood, other insects, rotting animals, poop, fungus, plants
• Bugscope Teammoths have lots of scales that make them look furry
• Bugscope Teambeetles eat a variety of things
• Teacheryes we can see the eye
• Bugscope Teamit depends on the beetle
• Bugscope Teamthere are so many beetles they can specialize in what they like to eat

• Bugscope Teamsome beetles eat plants only, others eat animals and plants... it varies on the specific species

• 10:19 am
• Bugscope Teamhere you can see the proboscis coiled up in the center of the head
• Bugscope Teamand you can see that the eyes are very round
• Teacherwhy do they have the hair
  Bugscope Teamthe hairs are called "setae", and they help the insect to sense it's environment. the setae are connected to nerves underneath the exoskeleton.
• Teacheris it hare
• Teacherhair
• Bugscope Teamthe hair helps them, for example, keep from getting stuck in spider webs

• Bugscope Teamsetae is pronounced 'sea-tea'

• Bugscope Teambut in this case what looks like hair is mostly scales, which are sort of like feathers

• Teacheris that a spot or a hole on the wing
• Bugscope Teammoths and mosquitoes and a few other insects have scales
• Bugscope Teamnow you can see that this moth was once in someone's collection

• Bugscope Teamit is a hole in the thorax
• Bugscope Teamremember insects have a hard exoskeleton around them. Think of it as a suit of armor. You won't be able to feel anything through that armor easily. So insects have "hairs" poking through that are connected to nerves to allow them to feel, taste, smell what's going on
• Bugscope Teamhwere there was once a pin
• Bugscope Teamwhere
• Teacherwhy are insects in the world

• Bugscope TeamWhen we make insect collections, we pin the insects throught their thorax to display them
• Teachertell more about this picture
  Bugscope TeamWe are looking at a close up of a moths wing. You can see the overlapping scales
• 10:24 am
• Bugscope Teaminsects can be very helpful and also can cause problems -- much like people
• Bugscope Teamthis is a portion of a wing
• Bugscope Teamit shows a number of the wing scales
• Teachera wing of what
• Bugscope Teama moth

• Bugscope Teamthe pattern of the scales can reflect light so that we see colors
• Bugscope Teamdifferent colors

• Bugscope Teamscales on a moth or butterfly are very similar to the feathers of a bird
• Bugscope Teamand speaking of colors...
• Teacherwhat are moths useful for
  Bugscope TeamMoths pollinate some plants, especially in the tropics. They are also very important food for birds and bats
• Bugscope TeamInsects are very important, they pollinate plants, they get rid of dead things and rotting vegetation, they are food for birds, lizards, frogs and mammals, and they produce a number of important products, like honey and wax and a number of dyes.

• Bugscope Teamthe reason our images are in black and white is because we are using electrons rather than light to collect the images we see

• Bugscope Teamelectrons are very small -- smaller than visible light

• Bugscope Teaminsects are part of the food chain
• Bugscope Teamsome moths are farmed for their silk, the silkworm moth is farm for the silk that it uses to build its cocoon
• Bugscope Teamso some of the things we like to eat would not survive if down the line there were now insects

• Bugscope Teamno insects would mean no fish, for example
• Teacherhow many eye's do they have
  Bugscope Teamthis is a fruit fly, so they have 2 compound eyes and 3 smaller simple eyes called ocelli
• Bugscope Teamwithout insects, a lot of pollination for plants wouldn't happen
• Bugscope Teamthe fruit fly will have hundreds to thousands of ommatidia -- the facets of the compound eye
• 10:29 am
• Bugscope Teamthis fruit fly has two large compound eyes, each one with hundreds of facets, called ommatidia, each one with its own lens
• Bugscope Teama fly has a highly developed sense of sight, which is why they can be so pesky!

• Teacherwhat is the hair coming off
• Teachercan a fly close thier eyes
• Bugscope Teamthe hairs (setae) are coming off of the eye
• Bugscope Teamthey cannot close their eyes
• Bugscope Teamand their eyes can get dirty, as we see here
• Bugscope Teamsome of them have fallen off, but the setae are inbetween the ommatidia
• Teacherdo insects sleep
• Bugscope Teamthe setae come out from between the ommatidia, uh, as Cate says

• Bugscope Teamthey don't sleep like we do
• Teacherwhat are the particals on his eye
  Bugscope Teamit's mostly dirt or something like that, we like to call it ju-ju
• Bugscope Teamthese hairs allow them to sense wind movement easily, like if a flyswatter or a hand were coming at them, they wouldnt feel the wind first and fly away before they get hit
• Bugscope Teamsome of the things on the eye are setae
• Bugscope Teamand some are dirt
• Bugscope Teamsometimes we see bacteria on the surface of the eye
• Bugscope Teamoh, yes, but the sticks laying across the eye are broken setae
• Teacherwhy do spiders have eight legs
• Teacherhow old do insects get before they die
  Bugscope Teammost of them are one year old, but some insects, like honeybee queens can live many years

• Bugscope TeamI think the way spiders move it is very handy to have eight legs

• 10:34 am

• Teachertell me more about what we are looking at
  Bugscope Teamthis is a haltere (the boxing glove) which beats opposite the wing to stabilize it during flight
• Bugscope Teamthis is the body of a fruit fly
• Teacherhow do insects get thier color
• Teachercan insects have freckels
• Bugscope Teamand we can see a hole in the side which in this case is supposed to be there -- it is a spiracle

• Bugscope Teaminsects do not have freckles like we do because they do not have skin like we do
• Bugscope Teaminsects have an exoskeleton; as Cate said they their skeleton on the outside of their bodies like armor
• Teachertell me more about what they use to breath
  Bugscope Teamthe spiracles can be found on many insects bodies. they are connected to the respiratory system
• Bugscope Teamthey breathe through the spiracles, which they can open as close as they wish
• Bugscope Teamthere are I think two spiracles on each body segment, usually on each side
• 10:39 am

• Bugscope Teamoh this is cool
• Bugscope Teamthis is a mite on the body of a ladybug
• Teacherwhat is a mite
• Bugscope Teambut it was not attached to the ladybug
• Bugscope Teamin some sharks and rays, however, spiracles are found behind the eyes, and those spiracles pump water to the gills while the animal is at rest
• Bugscope Teama mite is a very small arthropod that is often a parasite of some sort on a larger creature
• Teacherwhy are some spiders not posinous
  Bugscope Teamwell, most spiders can inject venom, and can kill its prey that way. but most of those venoms are not poisonous to humans
• Bugscope Teamif you take the mag down a bit you can see where it is

• Bugscope TeamAll spiders have venom but some are more choosey about when they use it

• Bugscope Teamthis is the 'chin' area of a ladybug if a ladybug had a chin
• Teacherwhat do mites eat
• Teachercan you tell how old a lady bug is by the spots they have
  Bugscope TeamNope, the number of spots on a ladybug only tells you what kind of ladybug it is. Insects don't change at all after they molt to adult form
• Bugscope TeamThey eat a variety of things like fungus, flakes of skin...
• Bugscope TeamAnd many time the venom of spiders is not harmful to humans. A human is way too big for any spider to eat
  Bugscope Teamgood thing for that too!!!!
• Bugscope Teamthe spots do not change on a ladybug -- it is an adult and will not change its spots

• 10:44 am
• Teacherwhat is the thing stiking out of the mites mouth
  Bugscope TeamI think that IS its mouth!
• Bugscope Teamnow you can see where the mite is in relation to the ladybug's head
• Bugscope Teamthe things sticking out of the front of the mite are its limbs
• Bugscope Teamand limbs ;)
• Teacherwhat are wee looking at now
• Bugscope Teampretty gnarly looking mouth, huh?
• Bugscope TeamAnnie is right, actually, since the mite feeds through its limbs
• Teacheris this the mouth of the mite
• Bugscope Teamthis is the head of the lady bug
• Bugscope Teamthe 2 vacuum nozzle looking things are a set of its palps

• Bugscope Teamyeah Cool
• Bugscope Teamsee how small the mite is? ladybugs are small, to us, and the mite is really quite tiny

• Bugscope Teamyou can see the eyes on either side of the head, on top, and you can see one antenna, on the left
• Bugscope Teamand as Cate says you can see the palps that we think resemble vacuum cleaner nozzles
• Teacherhow are lady bugs born
  Bugscope TeamLarvae hatch from eggs..the larvae eat and eat and grow and grow, then they pupate into adults
• 10:50 am

• Bugscope Teamthe life cycle of the ladybug is only 4-7 weeks :(
• Teacherwhy does the black widow spider have an hour glass on its bellie

• Teacherwhat are the insects siting on
• Bugscope TeamThe hourglass is red and likely signifies that the spider is dangerous. It keeps other critters from messing with it.

• Bugscope Teamoften insects/arthropods that are brightly colored and call attention to themselves are warning us that they are dangerous to touch or to eat
• Bugscope Teamyes, a brightly colored clear marking on any animal can serve as a warning to predators: stay away or i['ll mess up up man!
• Bugscope Teamthe insects are on silver paint and carbon doublestick tape
• Bugscope Teamthey are also coated with a few nanometers of the alloy gold-palladium
• 10:55 am
• Bugscope Teamwe cannot see the gold-palladium at these magnifications
• Bugscope Teamthe metal coating makes the insects conductive
• Bugscope Teamso that the electrons that impinge on them do not sink in and give us poor images
• Bugscope Teamthis is so pretty
• Teacherwhat is the spiders web made out of
• Bugscope Teamprotein!
• Bugscope Teamthese are tiny hairs but modified so that they can stick to surfaces
• Bugscope Teamwhen a spider is done with its web, it can eat it and make it again, kind of like recycling
• Bugscope Teamthe spider can produce web that is sticky, or not sticky
• Bugscope Teamand if it gets stuck in its own web it can eat its way out
• Bugscope Teamspiders inject venom into their prey, and the venom makes the inside of the prey turn to a liquid that the spider can suck out of the body
• Teacherwhat are the little dots on the sticky hair
• Bugscope Teamspiders think of their prey the way we think of milkshakes
• Bugscope Teamwe don't know what the dots do but it may be that they prevent the hairs from sticking too well
• Bugscope Teamthe tenent setae need to stick and then pull loose, repeatedly
• 11:01 am
• Bugscope Teami wonder if some spiders are lactose intolerant though...?
• Teacherare spiders picky eaters or do the eat whatever flys into their web

• Bugscope Teamthey don't like the taste of some things, like Monarch butterflies, and they will cut loose what they do not want to eat

• Bugscope Teamspiders can also sense when poison has entered one of their legs, for example, from something else biting them.

• Bugscope Teamthey can pop off a leg, if they need to, to get away
• Bugscope Teamwhen they sense a poison entering the leg, they can just let go of the leg

• Bugscope Teamin 1973, skylab took two spiders into space to test their web spinning capability in zero-gravity
• Bugscope TeamSorry that I have to leave early everyone. Thank you for your good questions!!!
• Bugscope Teambut the rest of us are still here teacher!
• Bugscope Teambye bye!
• Teacherbye bye annuie that you
• Teacherannie
• Teacherthank you
• Bugscope TeamAnnie is our entomologist.

• Bugscope Teamyes, she is an expert in beetles, and other insects as well
• Teacherwhat does that mean
• Bugscope TeamShe is a graduate student in entomology -- which is the study of insects
• Bugscope Teamshe is our bugologist
• 11:06 am
• Bugscope Teamshe studies, in particular, beetles that are called cerambycids -- longhorned beetles

• Bugscope Teamthe 'horns' are their antennae
• Bugscope Teametymology, which is the study of what words mean, is helpful in entomology
• Teacherwe really enjoyed this time of looking at bugs. Thank you for all your help, We learned alot and it will make us want ot study more about bugs and jobs like yours
• Bugscope Teamthank you for all your great questions
