- Teacherhello we are here now
- Bugscope Teamyay!
- Bugscope Teamhello!
- Bugscope Teamwelcome to bugscope!
- Bugscope Teamyou should have control of the scope now, you are welcome to start driging it anywhere
- Bugscope TeamHi Rick!
- Bugscope Teamdriving it, i mean
- Bugscope TeamOh Jimmy-John's is on!
- Bugscope Teamand Julie and Grace!
- Bugscope Teamthis is the face of a cricket, of course
- Bugscope Teamfeel free to ask any questions, we are here to guide you
- Studentwhat is the most interesting thing u have ever seen under a microscope
Bugscope Teamwell bugs are very interesting. there are lots of neat things on bugs that you can't see with your eyes: spiracles, setae, spinnerets, etc...
- Bugscope Teamif you drive a little south you can see the mouthparts
- Bugscope Teamof bug-like things I like finding mites on insects
- Bugscope Teamthe jumping bush cricket is the most common type of cricket in the US
- Studentdid you always want 2 be a scientist
Bugscope Teamscott and cate are scientists, i'm a computer dude
Bugscope TeamI've always liked science, working with microscopes makes it so I always get to be around it
- Studenthow do they chew
Bugscope Teamthey should have some type of jaws, but you can't see them easily here
- Bugscope TeamI like seeing stingers on bugs, they are cool
- Bugscope TeamI was in danger of being an English teacher and decided I'd better take some biology classes so I could do something else
- 1:22 pm
- Bugscope Teamso I got a degree in English and Biology and have been doing this (electron microscopy) for a long time
- Studenty does it look like it has hair on their eye
Bugscope Teamthat hair is called setae (see-tee), it is connected to nerves underneath the exoskeleton. those setae are how bugs sense their environment
- Bugscope Teamthey often do have what looks like hair
- Bugscope Teamthe hair-like things are called setae
- Studentwhat do they do
Bugscope Teamthe setae (hairs) have many different functions on insects. in general, they help the insects sense what is around them. Some will taste/smell/feel
- Bugscope Teamand setae are often sensory -- they can help the insect feel its environment, and/or they can help it taste the air, or smell
- Studentwhat do you do at your job???
Bugscope TeamWe do this...I also train people on the microscope you are using now as well as another electron microscope- the transmission electron microscope (TEM)
- StudentWhy did you choose this job?
Bugscope Teamwell, a job in the sciences and technical field is very interesting, you get to do different things each day, and it makes you feel good to use your mind
- StudentHOW WELL IS YOUR VISION
- Bugscope Teamwe train people to use microscopes, of all types, so they can use them to do their own research
- Studentwhat is the long tube going down the stink bug's head
- StudentWhat are we looking at?
- Studenthow do they eat
- Bugscope Teammostly we work with graduate students, sometimes undergraduates, and often postdocs -- people who have their PhDs and are just doing research
- Studentwhat are we looking at
- Bugscope Teamthe long tube is part of the proboscis
- Teacherwhat does this part do
- Bugscope Teamstink bugs are true bugs, which means, for one thing, that they have piercing mouthparts
- Bugscope Teamthis is part of the mechanism that lets the stinkbug move its proboscis around
- Studentwhy are there rippals on the proboscis
- Bugscope Teamwith a proboscis, you can think of it as an elephant's trunk, it can suck up juices through it
- 1:27 pm
- StudentWhats the pointy things on it
Bugscope Teamthose are more setae (hairs), and their function is to sense the wind movement. So if you swatted your hand at it, the fruit fly could feel it coming
Bugscope Teamthose are setae, sticking out inbetween the facets of the eye
- Studentwhat are we looking at now???
- Bugscope Teamit is either muscular or like one of those party favors that extends when you blow into it
- Bugscope Teamthis now is a fruit fly compound eye
- Studentare bugs warm blooded or cold blooded
- Bugscope Teamthey are cold-blooded, so they move slowly when it is cold
- Studentwhat is this?
Bugscope Teammonarch butterfly scales from a wing
- Bugscope Teamthis is part of a butterfly's wing -- the scales
- Studentthank you
- Bugscope Teamthese are tiny scales from a monarch butterfly wing
- Studentis this a cell
- Studentdo you know the average of how fast the bugs you look at go??
- Bugscope Teamthe scales are kind of like feathers to a bird
- Studentwhy are there lines on it
- Bugscope Teamnotice the holes in the scales. those holes allow for lighter scales, yet the wing still maintains good lift in the air for flying
- Bugscope Teamthe lines are ridges that help it keep its shape, and they are also thin enough that they refract light in different colors
- Bugscope TeamOOF as scott would say (out of focus)
- Studentdo u no how the tear happend?
Bugscope Teamthat could happen if someone were to touch the wing. It can tear easily, so I don't know the cause of it, maybe it happened when I picked it up
- Bugscope Teamwe think the scales are used to help give the insect lift in the air, but they also serve to help keep the insect from getting stuck in webs
- Studentwhat are the lines on the wing
- Bugscope Teamif the butterfly runs into a web the scales will stick and fall out and he/she can leave
- StudentWhat is best thing that you have ever looked at?
- Teacherwhat is a palp
Bugscope Teamit helps the insect to taste and manipulate food
- Bugscope Teamthis vacuum nozzle is a ladybug palp
- 1:32 pm
- Bugscope Teamwe did not answer the question about the average speed of these insects in part because it is hard to be definite about that
- Studentis this basically it's mouth??
Bugscope Teamno, it has 2 of these big palps on either side of its mouth
- Bugscope Teamthe palps are mouthparts that resemble accessory limbs
- Studentare those spikes or hair
Bugscope Teamthey are hair
- Bugscope Teamthis is right next to the mouth -- we won't be able to see an open mouth on this ladybug
- Studenthow does the bug contain water in its body
- Studentwhat is in the inside of the vacuum?
- Studentwhat are all the dots in it??
- Studentare they its tastebuds??
Bugscope Teamthey are analogous to tastebuds for us, yes!
- Bugscope Teamthose are sort of like taste buds, inside the vacuum cleaner nozzle -- yes
- Bugscope TeamD'Oh!
- Bugscope TeamCate is too fast for me
- Studentwhat are the little dots
- Studentwhat are the bumps under the mouth
- StudentDO THEY HAVE A TOUNGH
- Bugscope Teamthe little dots were the individual sensory buds
- Bugscope Teamladybugs do not have a tongue
- Studentare we seeing scales or cells
- Studentwhat may this particle be?
- Studentwhat is that?
- Bugscope Teamthey have chewing mouthparts
- Bugscope Teamit is juju we do not recognize
- Bugscope Teammay be oil from the sputter coater
- Bugscope Teamlike, a droplet of oil
- Bugscope Teamhere is one of the claws
- Student can u tell us about the brown beatle
- Studenthow do the bugs dispose their waste?
- StudentTell us about it
- Bugscope Teamthe claws work like one of those things people use to grab things off of a shelf
- Studenthow sharp is their claws?
- 1:37 pm
- Bugscope Teamthey have a part called an unguitractor on the inside
- Studentwhat are the small hairs above the claw
- Bugscope Teamyou can see that the claws are pretty sharp but they are also very small
- Studentwhat do ground beetles eat?
- Studentwhy does it have holes
- Studentwhat are the jobs of the claws
- Studenthow do they eat
Bugscope Teammost are predatory , but a few are omnivores, and even fewer just eat seeds
- Bugscope Teamthe small hairs are likely mechanosensory
- Studentwhat is mechanosensory
Bugscope Teamit means it is for movement or feel
- Bugscope Teamsome eat caterpillars, snails, slugs, berries...it depends on the species
- Studentdo they have a mouth?
- Bugscope Teamthe claws help the beetle grasp its food and walk on limbs, but these beetles do not have the ability to cling to walls or the ceialing
- Studenthow big are they?
- Bugscope Teamceiling...
- Bugscope Teamthis is the underside of the beetle mouth
- Bugscope Teamit has really big jaws
- Studentwhat are the finger looking things
Bugscope Teamthey are the palps, they do help move aorund food, which might explain why they resemble fingers
- Bugscope Teamand you can also see 2 pairs of palps
- Bugscope Teamcheck out the scale bar in the lower left of the image, 1 um = one micron = one millionth of a meter
- Studentare the little stuff in the mouth teeth
- Bugscope Teamyou can get some idea of the size by readfing the micron bar to the lower left
- Studentare those sensory hairs
- Studentwhat is the little rectangle in the center?
- Bugscope Teamfor example 304 microns is 0.304 millimeters, about 0.3 mm
- Bugscope Teamyes a lot of sensory hairs
- 1:42 pm
- Bugscope Teamthis is the center of the mouth
- Bugscope Teamwe are on the ant now
- Bugscope Teamthis is an ant comb, which does what it sounds like
- Bugscope Teamand now we see the comb-like structure on the ant leg
- Studentwhat is an ant's comb
- Studentwhat is it used for
- Bugscope Teamit uses this to clean its antennae
- Bugscope Teamit cleans the ant from debris
- Studentwhy are they so wing like?
- Bugscope Teamants use their antennae for communication much more than they use their eyes
- Studentis it like feathers
- Bugscope Teamthey are likely wing-like so they can be tucked in and out of the way
- Bugscope Teamfor your antennae
- Studentare the hair almost like cilia?
- Bugscope Teamants and other insects often get dirty and have to clean themselves off -- like you often see a fly doing
- Bugscope Teamthey are similar to cilia but I think are generally not motile
- Studentis that bacteria
Bugscope Teamoddly enough, we dont find too much bacteria on insects even though they are supposed to be covered in them. Bacteria are usually rodshaped and are around 2um big
- Studentwhat do ants eat
- Bugscope Teamthe reason there are so many setae is because they function as part of the sensory system
- Studentare those cob webs
Bugscope Teamno it is some sort of dust or dirt
- Studentwhat is the big blob?
- Bugscope Teambacteria are usually about 2 microns long and we don
- Bugscope Team't see any here
- Studenthow high of a magnification does your electron microscope go to?
- 1:47 pm
- Bugscope Teamyeah if there were bacilli we would be able to show them to you
- Studentare their any bacteria on bugs whatsoever??
- Bugscope Teamwe do see bacteria sometimes...
- Bugscope Teamyes we occasionally see bacteria on bugs
- Studenthow do they multipy?
- StudentHow much do you usually see?
- Bugscope Teambut it is usually after they die and start rotting
- Studentwhat is a spiracle
- StudentHow much bacteria sorry!
- Studentis that a mole
Bugscope Teamthis is the double stick carbon tape we use to stick the bugs to
- Bugscope Teamsometimes we will see individual bacteria, and sometimes small groups, like in the grooves between the eye facets
- Bugscope Teammiss smaha, your driving is adrift, do you need any help?
- Bugscope Teama spiracle is a breathing pore
- Bugscope Teamhere it is but the sample has drifted since we set the preset
- Bugscope Teamit looks like your image is drifting, are you sure your navigation is stopped? you may need to click inside the image to stop moving?
- StudentA pore like the same kiind of pore that gives humans zits?
- Bugscope TeamNENAD that is one of the spiracles -- there are usually two to a segment of the body
- Bugscope Teamwell those are breathing pores, so not like people have
- Studentwhat is the bill thing
Bugscope Teamlooks like a seta (which is setae singular)
- Bugscope Teampeople have skin, and insects have an exoskeleton
- Bugscope Teamthe exoskeleton is sort of like wearing armor would be, to us
- 1:53 pm
- StudentOk its Grace, do u know what kind of little bump we were just looking at?
- Bugscope Teamthe exoskeleton is a shell like a shrimp shell, of chitin
- Bugscope Teammiss smaha, when clicking to drive, click once to start moving, and you must click again to stop
- TeacherI can not get any thing i n focus
Bugscope Teamplease click in the image again, you are still moving now
- Bugscope TeamGrace the bump went by so fast
- Studenthow does it defend its self
- Bugscope Teamthere ya, go it is stopped, try clicking on a preset now
- Bugscope TeamMiss Smaha can you take the mag lower? That should help.
- Bugscope Teama preset is a great way to get a nice image
- Bugscope Teamwe were at 2500x, and it is hard to focus at that mag
- Studentwhat insect are we looking at now? (grace)
- Bugscope Teamnow we see what looks like silver paint
- Bugscope Teamhard to tell so far
- Bugscope Teamyou should be able to take the mag down lower
- Studentis it silver paint? (grace)
- Bugscope Teamlet us know if you need help
- Bugscope Teamah cool, this is salt from wendy's!
- Bugscope Teamsalt!
- Bugscope Teamthis always looks cool
- StudentWhy are there holes in the salt
- Bugscope Teamtheir salt is a little odd, it looks different from other salt strutures
- Studentwould this be considered grose?? (grace)
- Bugscope Teamwe think they put an anticlumping agent in it that makes it have those cool shapes
- Studentwhat is the difference
- Bugscope TeamGrace I don't think it is gross.
- Bugscope Teamnormal salt is kind of boring compared to this
- Bugscope Teamnormal salt will just look like cubes, wendy's salt has something else in it that gives it these cool aztec shapes
- Studentdo you know y the salt is always a cube?
- Studentis sugar like salt? (julie)
- Studentwhat is the stuff that gives it the shape and is it unhealthy
Bugscope Teamsalt, like most things, is unhealthy only is large amounts
- 1:58 pm
- Bugscope Teamsodium chloride forms cubes; sugar, for example, does not form crystals that are cubic
- Studentwhy are there squaresin the squares
- Bugscope Teamthe way the Na and the Cl fit together gives it that cube shape
- Bugscope Teamthe shape comes fomr the chemistry
- Bugscope Teamfrom
- Studentis the stuff on it like dead skin? (julie)
- Bugscope Teamthe chemistry of the individual components and the way they fit together
- StudentWhat is the wierdest thing you have ever seen under a microscope?
- Studentwhy is the end of it flat?
- Studentwht are they circular on the bottom
- Bugscope Teamthese hairs allow the insect to stick to walls and ceilings
- Studentare these like suckshin cups?
- Bugscope Teamwe have seen some weird insects/arthropods
Bugscope Teamthats what I think of them as
- Bugscope Teamyes they are like suction cups
- Bugscope Teammicro suction cups
- Studentwhat do these setae help the insect with? (grace) if they are setae!
- Studentwhy is it open on the end
- Bugscope Teamthey help the insect cling to ceilings
- Student why is it wrinkled up in the middle of the sucs
Bugscope Teamwhen the insects die, they dry up and shrivel a little
- Studentwhy are they so shriveled like a raisin
- Studentwhat are the lines
- Studentwhat are the wrinkles
- Studentare these there arms
- Bugscope Teamwhen they walk they can flex their tarsi and pull off of the surface that way
- Bugscope Teamthis is high mag, and it is hard to get perspective
- Studentwhat is the tarsi?
- 2:03 pm
- Bugscope Teamthe tarsi are the distal portions of the limbs -- the parts that are furgthest from the body
- Bugscope Teamfurthest
- Bugscope Teamso like the forearms and 'hands'
- Studentwhat are the circles in the backr
- Bugscope Teamhere you can see the cricket's eyes
- Studentwhat is behind the cricket head?
Bugscope Teamthat is carbon tape, used to stick to the bugs so they don't move around under the scope
- Studentwhy are the crickets antena appear to be cut
- Studentis that dust on it
- Studentwhy are there bumps on it's eye?
Bugscope Teamthe eye is a compound eye, meaning it has many facets on it that each collect an image
- Studentwhy does it look like it has a million eyes?
Bugscope Teamwell, that is called a compound eye, it actually does have hundreds of individual facets, each with a lens in it. flying insects often have very large compound eyes
- Teacherdo they have good vision
- Bugscope Teamthe background is doublestick carbon tape
- Studentthank you so much
- Studentis there bactiera on it's face?
- StudentThank You for teaching us about bugscope!!
- StudentTHANK YOU
- Bugscope Teami think their vision is pretty good
- Bugscope Teamthank you for all your interesting questions
- Studentthis was really great
- Studentthank u so much guys\girls
- Bugscope Teamyou all were awesome, thanks!
- StudentYou guys are very nice!1
- Studentthank you;)985
- Bugscope TeamOh...
- Bugscope TeamThank You!
- Bugscope TeamIt was fun working with you and we look forward to connecting again.
- 2:09 pm
- Bugscope Teammiss smaha, all the chat and images are saved on your bugscope member site: http://bugscope.beckman.uiuc.edu/members/2008-043
- Bugscope Teamwow, they are gone,
- Bugscope Teamthat was a fast logoff
- Bugscope Teamwait, miss smaha is back
- Teacherthank you so much be back next year
