- Bugscope TeamGerman cockroach head.
- Bugscope Teamhello alyssa!
- Bugscope TeamYay! Alyssa!
- Bugscope Teamwelcome to bugsfope
- Bugscope Teamthis is the eye of the cockroach
- Bugscope Teambugscope, silly me
- Bugscope TeamI just drove up to see it.
- Bugscope Teamyou have control, Alyssa, and can choose from among the presets, change the mag, drive off the edge of the world (not recommended)...
- Bugscope Teamlet us know if you have any trouble, or any questions
- 3:02 pm
- Bugscope Teamalyssa, do you see the chat?
- Teacherwhat bugs are we going to be looking at?
Bugscope Teamwe have a fruit fly, leafhopper, katydid, bumblebee, a few beetles, a damselfly-type insect, german cockroach
- Bugscope Teamleafhopper, katydid, a few beetles, a weevil...
- Bugscope Teamfruit fly, German cockroach...
- Bugscope Teamif you scroll though the presets, you can see all the presets that we made for you, lots of cool stuff there
- Teacheryes i do see the chat!
Bugscope Teamcool!
- Bugscope Teamand the bumblebee has a few mites on it
- Bugscope Teamand Alyssa can you see the controls, like Magnify, to the top right?
- TeacherI can not see the preset though
Bugscope Teamah, yeah, like scott said, click F11 to maximize your browser window... can you see them now?
- Bugscope Teamif your browser window needs to be resized you can hit F11
- 3:07 pm
- Bugscope Teamthe presets should be to the right of the chatbox here, and you should be able to scroll through them
- Teacherye ahg i tried to hit the F11 key and it still did not show the presets
- Bugscope Teamif maximizing your browser window doesn't work, you'll need to increase your screen resolution. i can help you do that if you need help
- Bugscope Teamok, we need to increase your screen resolution
- Bugscope Teamwhat are you using now, do you know?
- Teacherok! help
- Bugscope Teamok, step by step, i'll step you through
- Teacherim not even sure how to find out
- Bugscope Teamon the desktop, right click anywhere on it
- Bugscope Teamthen you'll see a menu pop up, click on properties
- Bugscope Teamdo you see that?
- Teacheryes im there
- Bugscope Teamcool, one of the tabs is resolution, that should tell you whaty the current screen resoltuion is, and you should be able to change it (if you have admin rights on the computer)
- Bugscope Teamcan you see what the screen res is?
- Bugscope Teamlike, the settings tab
- Teacherok! I took a gamble and it worked!
- Bugscope Teamoh wait wait, it's the "settings" tab, yes, i forgot that sorry
- Bugscope Teamcool, bugscope requires at least 1024x768 screen resolution
- Bugscope Teamso now you see the presets?
- Bugscope Teamyay! so you can see the whole browser now, and the presets, etc.?
- Teacheryes we can see it! OK we are going to start now!
- Bugscope Teamcool beans
- Bugscope Teamthis is a leafhopper
- Bugscope Teamsee the compound eye, and the little antenna tucked into the side of the head?
- 3:13 pm
- Bugscope Teamit's like a conehead
- Bugscope Teamthis is a profile view, it is facing left
- Teacheris this the eye ball that we are seeing
- Bugscope Teamtotally
- Bugscope Teamthat's a compound eye
- Bugscope Teamyes it is
- Bugscope Teamlike half a golfball
- Bugscope Teamyes I just kicked the mag up, but you can do the driving
- Bugscope Teameach little bump on it is an individual facet, with a lens. they are called ommatidia
- Bugscope Teamthe little furry stub to the left is one of the antennae
- Bugscope Teamnice job driving the scope alyssa!
- Bugscope Teammonster!
- Bugscope Teamfruit fly claw
- Bugscope Teamthis is a claw of a fly, a fruit fly
- Bugscope Teamif you take the mag down you can see where you are. the head is to the north
- Bugscope Teamthe fruit fly has six legs, and each has a claw like this on it
- 3:18 pm
- Bugscope Teamthe little things that resemble wilted flowers are tenent setae -- they help the fly cling to surfaces
- Bugscope Teaminsects are also really hairy. those hairs are called setae (see-tee) and they help the insect sense its environment
- Bugscope Teamcloser to the head....
- Bugscope Teamtake the mag down to see where you are
- Bugscope Teamor legs
- Bugscope Teamyou can see that it has a comb on it
- Bugscope Teamthe bumps in the background is the carbon tape we stick the bugs on
- Bugscope TeamYay!
- Bugscope Teamthe head of the fruit fly!
- Bugscope TeamAlyssa once you can see the sample you can try 'click to center' if you wish, to nail a certain place.
- Bugscope Teamthis is the eye, and you can see the antenna
- Bugscope Teamthe mouth (it has sucking mouthparts) is to the right
- Bugscope Teamsponging mouthparts really since it acts like a sponge :)
Bugscope TeamCate is right.
- Bugscope Teamthe little fur cave to the left and below the eye is one of the spiracles, through which insects breathe
- Bugscope Teamyou can see that the eye has lots of facets (the ommatidia), and there are also lots of little spikes sticking out of the surface of the eye.
- 3:24 pm
- Bugscope Teamflying insects have huge compound eyes compared to insects that live in the ground, like ants
- Teachertypical size for a fruit fly
Bugscope Teamthey are around 3mm big
- Bugscope Teamit's a compound eye, meaning that it is composed of all of those individual facets, which produce lots of images to process in the brain
- Bugscope Teamprobably 5 millimeters long
- Bugscope Teamoops
- Bugscope Teamthis is one of the mouthparts of a beetle
- Bugscope Teamit is a palp, which is what insects use to taste and to manipulate their food
- Bugscope Teampollen!
- Teacherit is not loading the image
- Bugscope Teamhit F5
- Bugscope Teamif you see a blank screen try refreshing your browser window
- Bugscope Teamor Refresh
- Teachergot it now
- Bugscope Teamdoes that work?
- Teacheryes it works now
- Bugscope Teamthe bumblebee was busy, picking up pollen
- Bugscope Teamthere are mites on the bumblebee as well
- Bugscope Teammites dont usually have any eyes
- Bugscope Teamthey are super tiny, not too much larger than the pollen grains
- Bugscope Teamif you take the magnification down, in steps, you can get an idea of the relative size of the bee and the mite
- Bugscope Teamit has powerful arms to help it cling to the bee
- 3:29 pm
- Bugscope Teamooh a roach! how did that get here?
- Bugscope Teamroaches are very streamlined
- Bugscope Teamthey have very simple features
- Bugscope Teamit looks like it has also started to decay a little bit maybe or just has some sort of gunk dried onto it
- Bugscope Teamyou can see that this roach had been in a collection, and someone had pinned it after it died
- Bugscope Teamroaches are able to live in a variety of environments
- Bugscope Teamthey are not specialized like, for example, a tick or a mosquito
- Teacherwhat makes them able to adapt well to harsh enviornments
- Bugscope Teamthey are relatively smooth and compact -- they don't have big frilly antennae, and as Cate said they are streamlined so they can squeeze into small spaces
- Bugscope TeamCockroaches have 2 autonomous brains - one in their head and one in their tail as a result they react to danger faster than the blink of an eye. They don't need both brains to survive - therefore cockroaches can remain active after their heads are removed.
- 3:34 pm
- Bugscope Teamcompare it to the leafhopper, with its big bulging eyes and its sort of triangular body shape.
- Teacherwhat is this
Bugscope Teamthis is a palp, one of the accessory feeding apparatus
- Bugscope Teamroaches have hairlike spines that stick out behind them, and if you touch them the roach will move automatically, without 'thinking'
- Bugscope Teamthere are mandibular (the lower jaw in people) and maxillary (the upper jaw in people) palps
- Bugscope Teamthe palps are like little limbs that can move around and help the insect taste as well as manipulate its food
- Bugscope Teamthe little things inside the palp, which looks like a jet engine, are like taste buds
- Bugscope Teamthey are tiny chemosensors
- Bugscope Teamthe chemosensors kind of look like little fingers
- 3:40 pm
- Bugscope Teamtwo mites!
- Teacherwhat are these on
- Bugscope Teamhere are 2 mites playing in bumblebee setae (aka bug hair)
- Bugscope Teamthey have soft bodies and are kind of shriveled since they died
- Bugscope Teamyes as Cate says these were riding for free on a bumblebee
- Bugscope Teamthey are small, even for mites
- Bugscope Teamif you decrease the magnification you can see where they are on the bumblebee
- Bugscope Teamjust a warning tho is the bumblebee is very large so you wont be able to see it all at once
- Bugscope Teamyes it is a very large bee
- 3:46 pm
- Teacherwow the kids are loving this
- Bugscope Teamnow you can start to see how small the mites are -- not much larger than pollen
- Bugscope Teampollen are like basketballs to mites
- Bugscope Teamsee the pollen grains through the hairs (setae)? to the right?
- Bugscope Teamleafhoppers (this is one of the claws) usually have tiny beads on them called brochosomes
- Bugscope Teaminsects always have six legs, and they have claws like this at the end of each leg
- Bugscope Teamthat little folded pad probably helps the leafhopper stick to the leaves it walks on
- Bugscope Teamleafhoppers like to drink the sap from leaves
- 3:51 pm
- Bugscope Teamyes leafhoppers and any other insect with a proboscis drink their food, whether it be plant sap or the insides of other insects, or our own blood!
- Bugscope Teamthe claws look very sharp but they are so tiny they would only tickle if it was walking on you
- Teacherany kind of leaves?
- Bugscope Teamthe scalebar in the lower left corner says 105 microns, which is about one tenth of a millimeter
- Bugscope Teamthey favor certain leaves depending on what kind of leafhopper they are
- Bugscope Teamsome like potato leaves and are thus agricultural pests
- Guestwats does this thing do cate
Bugscope Teamthis is a claw at the end of the leg
- Bugscope Teamwe don't know what kind of leafhopper this is...
- Bugscope Teamof a leafhopper
- Guestwats are does pointy things ae
Bugscope Teamthe 2 big pointy things are the ends of the claw. The spikes coming out of the leg are the setae (aka bug hairs)
- 3:57 pm
- Bugscope Teamthe background we see is the carbon tape the insects are stuck to
- Bugscope Teamnow we see tiny hairs...
- Bugscope Teamand now -- this is a cute little beetle cate found
- Guestok by every one scot and cate getting off
- Bugscope Teamsee it's antennae? and its forelimbs
- Bugscope Teambye lil d. thanks for stopping by
- Bugscope TeamThanks Lil D!
- Guestwait were is alex
- Bugscope Teamack I should've said its antennae, not it's, which means 'it is'
- Bugscope TeamHe had to go pick up a cable for a computer project
- Bugscope Teamwe gave Alex a break; he helped us set up earlier
- 4:02 pm
- Bugscope Teamsee the beetle mouthparts? when we put insects on the stage so we can image them, we put them on their backs so we can see their legs and their mouths
- Bugscope Teamit has segmented antennae going out on either side of the head
- Bugscope Teamwe can't see his eyes, but as Cate says we can certainly see his antennae
- Bugscope Teamyou are driving a $600,000 microscope from your classroom, and the samples you see are in a vacuum chamber. they're also coated with gold-palladium to make them conductive, because we are using electrons to get our images. electrons don't see color, which is why the images are in black and white like an old movie
- Teacherwow this has been amazing! thank you very much!!!
- Bugscope Teamof course if we did see color we would see silver...
- Bugscope TeamThank You!
- Teacherthe kids say "thank you"
- Bugscope Teamthank you! and as always you can get to your chat and images from today at your member page at http://bugscope.beckman.illinois.edu/members/2009-035/
