- 8:15 am
- Bugscope Teamhello, welcome to bugscope!
- Bugscope Teamwe are still setting up presets
- TeacherGood morning, I was just checking in while my first period class finishes another project. I will have two classes today - I hope that is okay. They both are about 40 people and will last about 45 minutes.
- Bugscope Teamyeah, that's cool
- Bugscope Teamone thing to note:
- Bugscope Teamwhen having your students login, it's best to keep the number of logins lower than 25-30, or else lag might be bad
- Bugscope Teamso, maybe you coudl double up your students on a computer?
- Bugscope Teamhowever, that's not a requirement, just a suggestion
- TeacherI have seven laptops for them to use so they will group up as table one, two, etc...
- Bugscope Teamah cool, that sounds great!
- 8:20 am
- Bugscope Teamwe'll be done with presets soon, and then you can practice driving... oh wait, you were logged in yesterday too right?
- 8:26 am
- TeacherYes, I was. I need to switch from my Mac system to the Windows so I will log out for a couple of minutes.
- Bugscope Teamok, no problemo
- 8:34 am
- Bugscope TeamWelcome to Bugscope
- 8:39 am
- Bugscope TeamLet us know when you have questions!
- Bugscope TeamLooks like something took a bite out of this part!
- Bugscope Teamthis is one of the mouthparts of this fly, kind of hard to see what is what
- Studentwhat is it
- Bugscope Teamthis is a fly proboscis
- Bugscope Teama proboscis is basically something that sucks up liquids of some sort
- Bugscope Teama type of mouthpart
- Bugscope Teamif you take the mag down you can see where you are
- Bugscope Teamthe biggest proboscis in the world is the elephant trunk
- Bugscope TeamHello Table 7
- 8:44 am
- Bugscope TeamHello to all the tables!
- Studenthi scot
- Bugscope TeamYou are in control of the microscope, Mrs D.
- Guesthi table 1
- Bugscope TeamHello Table 1
- Guesthi trevor
- Studentwhat is this
- Bugscope Teamlet us know if you have questions about the bugs, or how the microscope works, or anything else
- Studenthi joseph
- StudentOk, thank you.
- Studentha trevor
- Bugscope TeamIf you decrease the magnification a bit, you can see the rest of the fly's head
- StudentHey guys, this isn't an Im, please stop.
- Studentcomo estas
- Studentmuy bien
- Studentstop saying hello to everyone
- Studenthow many eays does it have
Bugscope Teamwell, it has two large compound eyes
- Studentthis is for questions only
- Bugscope Teambut i think some insects have simple eyes as well, i know spiders do
Bugscope TeamYes, some (but not all) insects have simple eyes in addition to compound eyes
- Studentthank u
- StudentWe saw yesterday that these things have minipoop, is there any of this "poop" on the table?
Bugscope Teamtable 3 we will see some if you look around -- entomologists call it 'frass'
- Studentwat is it
- Studenta fly
- StudentIt is a fly
- Guestwat part is this
- Bugscope Teamyep, this is a fly, but probably not a house fly like i said before
- Studentwhat gender is it
Bugscope Teamwith flies (Diptera) you can sometimes differentiate between male and female by looking at the eyes
- StudentOh ye, we saw that.
- 8:50 am
- Studentwhat does the fur on it do for the fly?
Bugscope Teamthat fur is called setae (see-tee), and those are hair like structures that stick through the exoskeleton, these hairs are how insects feel their environment
- Studentis it a male or female
- Studentis the hole really that big in the bug?
Bugscope TeamThis insect was part of a pinned collection...the hole is where the pin used to be.
- Studentwhere can they be found at?
- Studentis that the hole from the metal toothpick thing?
- Bugscope Teammale fly eyes are often close together, and those of females are further apart
- Studentye table 2
- Bugscope TeamThe hole is not very big in proportion to the rest of the fly
- Studentoh i thought so
- Guestwat is that
- Studentwild needs to talk regular
- Bugscope Teamthat is/was the head of the fly
- Studentis that the eye
- Guesto thanks
- Bugscope Teamit has huge compound eyes with thousands of facets, called ommatidia
- Studentis this the eye
- Bugscope Teamyep, this is the compound eye
- Bugscope Teamyes that is the eye, on the right just now
- Bugscope Teamfly's have very good vision, thanks to these compound eyes
- Studentok cool
- Bugscope Teamin the background we see bubbles in the doublestick carbon tape Cate used to mount the samples on the stub yesterday
- Bugscope Teameverything we see is inside the vacuum chamber of a scanning electron microscope
- Bugscope Teammrs. dobler, you can also click on any preset to take you to that location, if you like
- Bugscope Teamand it is coated with several nanometers of gold-palladium
- 8:55 am
- Studenton estimate how many eye spots are in a compound eye? normally?
Bugscope Teamwell, it ranges from maybe a hundred, to thousands. flying insects usually have more facets (ommatidia) on them, because they need better vision.
- Studentis that a leg or arm?
Bugscope Teamthey are all legs
- Studentis that a leg
- Studento ok thank you
- Studentis that a pincher
- Bugscope Teamthere are hundreds to thousands of ommatidia on the eye of a flying insect
- Studentwhat are ommatidia?
Bugscope Teamommatidia are the individual facets of a compound eye. all those bumps on the compound eye are ommatidia. each one contains a lens and sends a vision signal to the fly brain
- Studentis that hair?\
Bugscope TeamWe call insect "hairs" setae. The setae allow the insect to sense its environment through its thick cuticle
- Bugscope Teamsome flying insects, like bees, flies, wasps, also have three ocelli -- simple eyes -- on the top of their heads
- Studento ok thanks
- Bugscope Teaminsects are a lot hairier then they seem. insects have a hard exoskeleton that is like if you were wearing a suit of armor. If you just had the suit on, you would bump into stuff and not really be able to feel it. Insects have holes in their "armor" with setae (insect hairs) sticking out that are connected to nerves underneath. These setae allow the insect to sense their environment.
- Bugscope Teamplease be sure and click on another preset to go to a different insect/arthropod when you are ready
- Studentis it strong
- Studentcan't the fly only sense whats in front of him, instead of seeing an image like us
Bugscope Teamwell, the lens's in the compound eye are fixed, so they can't move it around. but you'll notice that the ommatidia are many hundreds, and pointed in a wide range, so in fact the fly can see a wide angle, probably better than we can
- Bugscope Teamyou all are doing a great job, asking real good questions!
- Bugscope Teamand let us know if you have any trouble driving
- Studentwhat is that?
Bugscope TeamThis is the edge of the eye...woops, not anymore
- Studentis that its ear
Bugscope TeamInsects don't typically have "ears" like we do. Many insects sense their environment with setae that sense vibrations.
- Studentlets go to a different bug
- Studentwhat are the bumps???
- Studentis that an ear?
- Studentok thank you
- Studentcan we go to a different bug mrs. D?
- Bugscope Teamhere we are looking at the cuticle, and the small ball like things are pollen grains
- Studentwhat is the hair on it?
Bugscope Teamthose hairs are called setae (see-tee) and they are like cat whiskers in that they help the insect to sense its environment
- Studentreally i didn't know that
- Guestwhoa wat is that
- Studentwhat are those shell looking this?
Bugscope Teamthose are scales
- 9:00 am
- Studento so they help it figure out where it is?
- Bugscope Teamthis is a green iridescent beetle that resembles a weevil but does not have a snout, and it also has scales, as Alex said
- Studenthow many compounds does it have?
Bugscope TeamTwo compound eyes
- Studentwhy are some of the scales together and some apart
Bugscope Teamwell, they can fall off or be dislodged. often the scales might come off on purpose, as is the case with a moth that might be trapped in a spider web, it'll shed it's scales so it can fly away. i think butterfly's do that too, scott, annie?
- Studentwhat is the texture of the scales?
Bugscope TeamYou really won't be able to tell that they are scales. They might feel a little like dust or sand particles.
- Studentwhat do the scales do????
- Bugscope Teamvert few insects besides mosquitoes, butterflies, moths, and silverfish have scales
- Bugscope Teamvery
- Studenthi cate
- Studentok thanks
- Bugscope Teamin this case the scales contribute to the color of the insect -- to the green iridescence
- TeacherWhat are the scales for/
- Studentwhat do the scales do for the bug and why are they there?
Bugscope TeamScales have a number of functions. In some insects, they contribute to their color, as Scott said. The color can help them to blend in with their environment or to warn predators. Some insects have scales because it makes them slippery, and less likely to be caught by predators/ spider webs. If you have every tried to catch a butterfly you know how hard it is to hold onto them. That is because they are coated in slippery scales that you rub off when you touch the surface of the wing.
- Studentwhat are the scales made of???
- Studentwhat is that thing taht is off of the scales?
- Studentwhat is that thing
Bugscope Teamon the very right of the screen is part of a leg and just to the left of that was part of an antenna
- Bugscope Teamoop
- Bugscope Teamif you take the mag down we can see what the whole dude looks like
- Studentwhere is the antennae?
- Bugscope Teamwe have Annie, our entomologist, curious to see it
- Studentis tha ta leg?
- Bugscope Teamthis is a portion of the arm
- Studentscroll down christina
- Bugscope Teamnice job controlling the scope mrs. d!
- Bugscope Teamand now we see the whole top of the body -- Thanks!
- StudentMorgan go to spider fangs!!!!!!!!!
- 9:05 am
- Guestwat is it then?
- Bugscope Teamcool, SPIDER FANGS
- Bugscope Teamhere is your spider
- Studentis that the hair setae
- Studentsuper cool
- Bugscope TeamI am not sure what kind of beetle that was...I will have to take a look at it later
- Bugscope Teamfangs!
- StudentSPIDER FANGS!
- Studentthese are spider fangs!!!!
- Studentvery hairy
- Studenthey wild.
- Bugscope Teamyep, the fangs are pointed towards the center of the image
- Guesthey andrew
- Studentwhy are they hairy
Bugscope Teamalmost always, hairs are there to help the insect/spider sense its environment, with mechanosensory or chemosensory setae (see-tee)
- Studentis this bug venoumous?
- Studentis that joseph
- Studentjoseph r u wild
- Bugscope Teamspiders inject venom into their prey that dissolves the insides of the prey, and they then suck that liquid out like a milkshake
- Studentyes this bug is venimous!
- Guestu spelled my name wrong buddy
- Bugscope Teamyummmy yummy bug milkshakes
- Bugscope Teamall spiders are venomous
- Studentdoes this spider have venom
Bugscope TeamAll spiders have venom
- Studentwhat prey does this spider eat
Bugscope Teamanything smaller than him!
- Studentoh thank you so very much.
- Studentevery bug is venimous?
Bugscope TeamNope, not every insect. Every spider is, though.
- Studenti mean spider?
- Studentdo the fangs liquify the prey
Bugscope TeamNot the fangs, the venom that is ejected from the fangs
- StudentIs this spider very posinous?
Bugscope TeamNot unless you are a small arthropod
- Studentis the hole by the fangs a mouth? and is it a wolf spider
- Studentfangs are cool
- Bugscope Teamit is deadly to small arthropods
- Studentcan spiders eat peple
Bugscope Teami think if there was a game of spider vs. humans, and the winner is the one who eats more of the other, humans would win hand down, no contest.. that's true with a lot of species of animals as well
- Studentare those a separate pair of fangs
- Studentdo the fangs still have venom in them?
Bugscope TeamProbably not, it is most likely all dried up
- Studentits people
- Bugscope Teamsome spiders can hurt people by biting them, but spiders do not eat people
- Studentyes the fangs do
- Studentwhat do they eat?
- Studentis it a wolf spider
- Studentthis is a cool wolf spider
- Bugscope TeamIn all actuality, some people have severe allergies to spider bites in which case, this spider could harm a person. Then again some people have severe allergies to peanuts, but we don't walk around in fear of peanuts or squish peanuts and throw them out of our houses.
- 9:10 am
- Studentwhat is that
- Studentwhat are the two tube things on he screen
Bugscope Teamthose are where legs used to be. spiders have a cool function where they can shoot off their legs if it will help them get away from predators. This also makes it easier for legs to pop off after they are dead and dry
- Studentthe screen
- Studentwhat is that
- Studentare those legs and are they cut off
- Bugscope Teamyes those are the stubs of a couple of legs
- Studentwhat is that
- Guest that where the pin was?
- Teacherwhat is the hole???????????
Bugscope Teamthat is where the pin was stuck in the spider
- Studentwhy does this spider need so much hair???
Bugscope Teamwell, the exoskeleton doesn't have nerves in it. the only way the spider can feel it's surroundings is thought these hairs. so over time spiders that have more hairs (setae) might survive better than ones that don't, so what your left with are lots of hairy spiders... that's one idea about it anyway ;)
- Guestsorry is
- Studentis it a wolf spider? please answer?
- Studentit is where the pin was
- Studentit is the needle hole
- Bugscope Teamtable 5 we are not sure what kind of spider it was
- Studentis this table 5 wolf spider
- Studentbrown recluse
- Student >:-(
- Teacherwhat are the other holeish things??
Bugscope Teamat the top left side of the screen is where the spider legs have popped off
- Bugscope Teamwe cannot always tell, and spiders have soft bodies that shrivel quite a bit after they die, making it more difficult to identify them
- Studentwhat sideare we looking at the top or bottom
- StudentOkay we understand thanks for trying
- Bugscope Teamthis is the ventral side -- the underside
- Teacherhey do we want to move on to the head of the Yellow Jacket
- Studentwhy is the legs that are broken off have no hai?
Bugscope Teami think those were the sockets of the broken legs, so the internal sockets wouldn't need setae (hair)
- Studenthow many eyes do spiders have and can it vary
- Teachernew bug!!!!!!!!!!!!!!
- Bugscope Teamwe almost always mount insect/arthropods upside down so you can see the legs, the mouths, etc.
- Studentwhat is this?
- Studentwhat is it
- Guest bee
- Bugscope Teamhere is another insect you sent-- a yellow jacket
- Bugscope Teamthis is a yellow jacket, like cate says
- Teacherare those pinchers
- 9:15 am
- Studentoh is that the bee?
- Studentwhat form of mouthparts are these
Bugscope TeamThis are mandibulate mouthparts.
- Bugscope Teamright on mrs. d!
- Studentwhat do pinchers do??
- Teacherthey pinch
- Studentare those strongly developed pinchers
Bugscope TeamThey are jaws--they help the yellowjacket to eat and to manipulate things--like a dog does...
- Studentyeh right on!
- Studentthat looks like the peeling of oranges
Bugscope Teamlots of things look very odd, or take on different looks, when looking at them under an electron microscope
- Guestit does?
- Studentwhat do they eat, plant or other bugs?
Bugscope TeamOther insects and dead things. Yellow jackets LOVE to eat roadkill
- Studentnot really
- Bugscope Teamyou can see the eyes on either side of the head, and you can see the antennae around the edges of the image we see now
- Studentyes it does
- Studenthow long are their legs by our point of view?
Bugscope Teamthere is a scale bar in the lower left of the image, if you focus on a leg, then we can figure out the measurement no problemo!
- Guesti agree with table 5
- Studentits teeth
- Studenthow many segments are on the legs?
Bugscope Teamfrom the body outward, insect legs usually have a coxa, trochanter, femur, tibia, and a number of tarsi -- the forearm segments
- Studenti had no idea that yellow jackets liked eating road kill
- Studentis that a wing
- Studentdo they lay eggs in the spring in America?
Bugscope TeamFoundress queens overwinter as adults, then they lay eggs and start colonies in the spring.
- Studentwhy does it have so many layers
- Bugscope Teamack, click again to stop!
- Bugscope TeamYellow jackets are the junk food junkies of the insect world. They like softdrinks, sticky candy, fatty food, and rotting meat.
- Studentwhat is that
- Studentwhy does it have layers on it legs????
Bugscope TeamDo you mean segments? Each segment is rigid and can only move so much, so there are a number of tubes of cuticle that move together...think of a suit of armor, there are a number of plates that fit together and the are flexible in places, which allows the wearer to move
- Studentwhat are those spiked orbs
- Studentwhat is that?
- Bugscope Teammrs. dobler, we drove off the edge of the scope stage, so we fixed the scope and clicked on a pollen preset for you, you should now have control again
- Studentits pollen
- 9:20 am
- Bugscope Teamthis is a pollen grain on the body of the fly
- Studentwhat is the pollen on
- Studentthank you
- Bugscope Teammade me sneeze
- Studentthat thing looks really cool
- Studentdon't sneeze Scot!!
- Studentthat is so cool!
- Studentgo to new slide
- Studentohh wow tiny
- Bugscope Teambacteria are often 2 microns (micrometers) long
- Bugscope Teama micrometer is one millionth of a meter = way way small dude!
- TeacherCan you transfer control of the microscope to me at the "new" Mrs Dobler - I got logged out by a "student driver"
- Bugscope Teamso we would have no problem seeing bacteria if there were any
- Studentwhat are the prickles under the pollen
- Studentok i get it now!
- Bugscope Teamtable3 the prickles are setae on the body of the fly
- Studentthank you
- Bugscope Teamha!
- Bugscope Teammonster!
- Studentoh ic
- Studentit has horns
Bugscope Teamheh, well, those are antenna that are broken
- Studentwhat is this?
- Bugscope Teamcibarium!
- StudentMrs. Dobler could we see the yellow jackets stinger?
Bugscope Teamthe stinger was not visible today
- Bugscope Teamthis is the head of the cicada
- Studentwhat part of the bug is this
- Studentwhat the heck is that
- Studentwhat is that? its scary looking?
- Teacheris that near the head?
- Studentwhat is a cibarium
- Studentdoes it have any eyes
Bugscope Teamthe eyes are hard to see but they were on the far sides of the screen when we were looking an the tympanum
- Studentit looks like it has ribs
- Studentwhat is that tube in between the legs
- Bugscope Teamthe tube is the proboscis
- Teacheris that a torn off leg?
- Bugscope Teamhaha, the center of many insects that suck plant juices have a "pump" in the center of their head. It is called the cibarium. It is kind of like a squeezy bulb--the insect compresses it and releases it and the change in pressure sucks juices into its mouth
- Studentwhat is their dietuj6uj
Bugscope TeamThey feed on root juices as nymphs. Adult cicadas do not feed.
- Studentthats my pet cicada phil!!!!!
- 9:25 am
- Studentlater homies
- Studentwhos phil
- Studentbuh bye
- Studentcya joe
- Bugscope TeamThank you!
- Bugscope TeamThank you for connecting with us today!
- Studentmi cuchara es de masiano grande que
- Bugscope Teamyou all did awesome. you rock and or roll!
- Bugscope Teamde nada table dos
- TeacherWe now have a five minute break between classes and it will be an entire new group.
- Bugscope Teamok, no problem mrs. d, you all are doing great
- Bugscope Teamand your scope driving is excellent
- 9:34 am
- TeacherMy forty students are ready to fire questions at you...
- Bugscope Teamok, we are ready!
- Bugscope Teamgreat!
- Studenthow long do it take to decay
- Bugscope Teamwelcome to bugscope students!
- Studentwat are the broken rectangular things in the cicadea?
- Bugscope Teamthis is the edge of a butterfly antenna
- Studentis it a boy or a girl
- Bugscope Teamit does not take long for something to decay once it dies
- Studentdo they have a scales
- StudentWhat are the strings attached
- StudentWhy is the texture different.???
- Bugscope Teamwith insects it can be hard to tell, sometimes, boys from girls
- Bugscope Teamyep, moth, butterfly's, they all have scales
- Studentoh about how long does it take?
- Studentare they falling off?
Bugscope Teamyep, some scales fall off on purpose, it can be a defensive mechanism, like if the butterfly is trapped in a spider web, its scales will fall off and then it can fly away
- Studentwhat kind of butterflie is t
- Studenthow do you know wether it's a boy or girl
- Bugscope Teamhere we see some scales, which fall of easily, and also some setae on the surface of the antenna
- Studentwhat are those patterns?
- Studenthow do blood flow
- StudentHow many
- Studenthow many
- StudentHow much does it cost for one of the microscopes?
Bugscope Teamthis scope cost about $750,000 in 1998
- Bugscope Teamhow many what?
- 9:39 am
- Studentwhat do butter flys use the antennas for?
Bugscope Teambutterflies use their antennae to pick up scents in the air -- such chemical signals as pheromones, for example
- Bugscope Teamsometimes boy flies have eyes that are closer together, sometimes insects have stinger/ovipositors that let us know they are females, sometimes the female is plumper and larger because she is carrying eggs...
- Studenthow mANY SCALES
Bugscope Teamwell, hmm, i don't know, looks like hundreds, if not thousands of scales
- Bugscope Teamthere are thousands of scales
- Studentis this a tail?
- Studentdo they have pattern on them
Bugscope Teamyes, those patterns often produce color of the insect, by the way the scales reflect light
- Studentwhats the black line??
Bugscope Teamthe black line looks to be a crack in the carbon tape that we set the insects on
- StudentHow longz do they live for.???
- StudentWhat kind of bug is this?
Bugscope Teamthis is a butterfly antenna
- StudentWhat is that?
- Studentwhat part of the bug are we looking at?
- StudentWhat are we looking at now?
- Studenthow long does it take to run the microscope?
Bugscope Teamthe microscope takes a few minutes to pump down, and then it is pretty easy to run
Bugscope Teamoh, not long, about 5-10 minutes to prep a bug sample and start up the scope, which involves pumping a vacuum chamber so the electrons can bounce freely inside the scope chamber
- Studentwhere do the sound come from they make
- StudentCan we see a picture of the eyes?
- Studentwhat do they eat?
- Studenthow long do they live?
- Bugscope Teamthis is another antenna, but on a fly
- Studentcan we see the eyes$$$$$$$$$$
Bugscope Teamtable 4 the eyes are just below where we are now
- StudentWhat kind of fly is this.???????
- Studentwat is all that hair?
- Bugscope Teamsure, mrs. dobler has control of the scope, ask her to move to a compound eye preset
- Studentshe said no
- Studenthave you ever scanned a dustmite
- Studenthow high do they fly
- Studentdoes this microscope only show up in black and white?
Bugscope Teamgood question! the answer is yes. since the electrons are being used to gather the image, there is no frequency of light involved, so the image is simply a mesh of grey-scale. we can, however, color the image after the fact, based on elemental analysis
- Studenthow do flys mate with other flys?
- StudentWhat kind of fly is this.?!?!?!
- Bugscope Teamthis is one of the compound eyes of the fly
- Studentwhat is on the eye?
- Studentare all those millins of eyes?
- Bugscope Teamthis may be some kind of biting fly -- we are not sure
- Studentwhy are the eyes so big?
- Studenthow many pimpels does it have
- Bugscope Teamthere are thousands and thousands of individual facets to this eye
- Studenthi scott
- Bugscope Teamthe facets are called ommatidia
- 9:44 am
- Bugscope TeamHi Table 5!
- Studentwhat are on the eyes?
Bugscope Teamwe can see scales from other insects on the surface of the compound eye
- Studenthi cate
- StudentWhat are the hairs
Bugscope Teamthose hairs are called setae (see-tee) and they function a lot like cat whiskers in that they help the insect to sense its environment. setae stick through the exoskeleton, to nerves underneath, and that's how they send feel signals to the insect
- Student0o0 OKAY i SEE
- Studentare compound eyes better than single eyes
Bugscope TeamCompound eyes give insects the advantage of being able to process motion very quickly compared to our eyes
- Studentis that an intenna?
- Studentwhat are we looking at?
- StudentNumber 4 is all a's in class
- Studentis this its wing?
- StudentScot is that a wing?
- Bugscope Teamthis is a wing, yes!
- Studentdo flies see black and white or colored
Bugscope TeamI think they see in color; many insects do
- Studentare those lines veins?
Bugscope Teamthe lines on the wings were veins
- Studentwhat is that
- Student this program is technically intruge
- Studentare those little things hairs.?
Bugscope Teamthe things that resemble hairs are called 'setae,' and they are often sensory
- StudentHOW OLD IS THIS THING.??
- Studentwhat are the bumps
- Studentsorry about that
- Studentthis thing is scary looking
- Studentis that the head?
- Bugscope Teamyep, this is the head
- Studentis this the mouth?
- Bugscope Teamwith compound eyes on either side, antenna above, and mouth pinchers too
- Studentis that the mouth?
- Studenti like flyes
- StudentThis is sexy
- Bugscope Teamthat is the mouth, yes
- 9:49 am
- Studentwhat are the things on his head why are there so many
Bugscope Teamyou mean those hair looking things? those are setae, and insects have thousands of them all over
- Studenthow many legs do it have
Bugscope Teaminsects, as adults, have six legs
- Studenthow often does a flie poop
- Studentdoes it have a anus
- Studentis the arm broken?
Bugscope Teamyeah, on the left, it does look like a broken antenna, or leg...
- Studentdoes a fly poop every time it lands on something/
Bugscope Teamwell, not everytime, but quite often
- Studentand or puke?
- Studentbecause that is what i have heard
- Studenthow do it attack there prey
- Studentwhat is the black holw?
- Studentdoes this bug have teeth?
- StudentEWK WHAT IS THAT OPEN AREA.??
- Studentwhats the hole
- StudentIn the summer flys are attracted to my dogs poop why is that?
Bugscope Teamwell, i'm not sure, but it's most likely having to do with some kind of feeding it is doing, to survive
- Teacherwhat section is this
Bugscope Teami'm not sure, if you lower the mag, we can get a better idea of what we are looking at... oh, scott knows..
- Studenthow does a fly ear
Bugscope Teamflies hear using their setae, usually -- they do not have ears]
- Bugscope Teamthis is the thorax
- Studentwhat are we looking at
- Studentwhat is this part?
- Studentwow you guys are smarticle
- Studentis this the leg?
- Studentwhy dont you guys answer!!!!!
- Bugscope Teamyou guys are doing awesome, great questions, and mrs. dobler is a pro at controlling the scope!
- Studentis this his claw.???
- Studentis that a pincher
- Studentwah is it.?!?!?!?!\
- Studenthow many parts does a wasp have
Bugscope Teama wasp would have three main body parts -- the head, thorax, and abdomen
- Studentwhat does fly eat?
- 9:54 am
- Studentwhat is that thing a pincher
- Studentdo they have senses?
Bugscope Teamyep, they can see with their eyes, they can feel with their setae (hairs), and they can probably taste, although that would be very hard to measure by humans because we can't talk to fly's and ask them what things taste like
Bugscope Teamthey have chemo, mechano, and thermo senses
- Bugscope Teamthe claw is much like a tiny pincher
- Studentcan we see a dustmite
Bugscope Teamwe could see a dustmite if there was one
- Studentwhat is is the body part that we are seeing now
- Bugscope Teamthis now is the head of the cicada
- Studentthe eyes?
- Studentwhat is this
- Studentwow that is so cool
- Studentare those the eyes?
- Studentwhat are the horn like things on top
- Bugscope Teamthe eyes are almost out of the image on either side
- Studentwhat is the bumps on it
- Studentwhat is that thing
- Studentwhat is the webbings?
- Studentare those things on its head eyes
Bugscope Teamno, those were broken antennae, i think that's what you were referring too.
- Studentdo u have a dustmite
- Studentwhat is the crack in the center spot?
- Bugscope Teamtable 1 we do not have any dustmites that we know of on this stub
- Studentwhat family is a wasp in
Bugscope Teamwasps are in the Family Vespidae
- StudentDo they only come out every 4 years??
- Studentyup that was right
- Bugscope Teamdustmites are hard to preserve because they shrivel up like aphids when they die
- Studentwhat is the tube that is sticing out
Bugscope Teami think that tube was a broken antenna
- Studenthow many times does a insect usally molt
Bugscope Teamgood question, it differs for different insects. some molt once, and other molt each season, etc.
- Studentwhat is this?
- Studenthow long do it live
- StudentHow many admins are there?
- Studentwhats a aphid?!?!?!?!?!?!?!
- Bugscope Teaman aphid is a insect that lives on plant fluids
- Studentdid its arm come off?
- 9:59 am
- StudentIs that a leg?
- StudentAlex how many years do they live?
Bugscope Teamhow many years does what live?
- Bugscope Teamthis is the spider!
- Studentwhy is it all hairy
Bugscope Teamthe 'hairs' are an important part of its sensory system

- Studenthow do leeches move
Bugscope TeamLeeches have two ways of moving around. 1- They will swivel their flat bodies while in the water to propel foward. It almost looks like their whole body is doing the wave. 2- They wil outstrech thier front sucker on a rock, while the end sucker clings on to the other side. The front sucker will cling on to the rock and the leech will be streched out fully. The end will release itself, and inch foward, and will repeat to get around.

- Studentwhat do centipes eat and how poisonious are they to people
Bugscope TeamThey eat insects, spiders, and other small invertebrates. If the centipede is large enough it will even attack small vertebrates like lizards.
Bugscope TeamI'm not sure how poisonous they are to people. They are poisonous to insects much like how spiders are poisonous. Maybe if a person was allergic to the venom it would be harmful, otherwise it would be like getting a spider bite from a house spider
- Bugscope Teamspiders also have soft bodies, and can get hurt easily
- Bugscope Teamspiders are also predatory, so they lurk and surprise their prey (food)
- Bugscope Teamspider thus like hanging out in dark places, thinking that gives them a lurking advantage
- Studentis it true true that the daddy long leg is the poisenis spider?

- Bugscope TeamGoing off of what Leeches are hermaphrodites meaning that a single individual is both male and female at the same time. Reproduction occurs through the production of cocoons that are either attached to a substrate where they develop or in the family Glossiphoniidae many species of leeches have the cocoons attached directly to the ventral surface of the parent. This allows the parent to protect and care for the young as they develop. This includes providing food (prey) for the young leeches after they hatch.
- Bugscope Teamthese are tenent setae, which help insects stick to walls and smooth surfaces
