- Bugscope Team sample is in the 'scope and pppumping down
- Bugscope Team now we're making presets for today's session
- Bugscope Team hello
- Bugscope Team Greetings.
- Bugscope Team We are ready here. Mrs. Haworth, you have control of the scope.
- Bugscope Team If you've done this before, then you know what to do. If this is your first time - or need a refresher, let me know and I'll give you some pointers.
- Bugscope Team wasp eye facets
- Bugscope Team ommatidia
- Teacher Good morning
- Bugscope Team Yay!
- Bugscope Team Welcome back!
- Bugscope Team Scott is driving around a bit, but feel free to take control at any time. The presets to the left are a good place to start. Click the blue arrow to reveal them.
- Bugscope Team Greetings!
- Bugscope Team please let us know, of course, whenever you have cuestiones.
- Bugscope Team we cannot see the venom pores, as far as I can tell -- I looked this morning
- Bugscope Team (the pointy crossed things here are the fangs)
- Bugscope Team the large fibers are fibers from a plant, likely, not web
- Bugscope Team the fangs are at the ends of the chelicers, or chelicerae
- Bugscope Team if we were able to see it from the other direction, we'd see that the chelicers originate just under the eyes
- Teacher Good morning
- Bugscope Team Good morning! Can you see this?
- Teacher Yes, we were disconnected for a minute, but we're back now.
- Bugscope Team sweet!
- Bugscope Team Glad you're back!
- Bugscope Team please let us know if you have any questions, need any help with anything, ...
- Bugscope Team you know that you can choose from any of the presets on the lefthand screen
- Teacher What type of spider is this?
Bugscope Team not really sure -- we're not good with spiders -- it is apparently a female...
- Bugscope Team males have large palps, and I believe, if we check lower on the cephalothorax, we'll see two gonopores.
- Teacher How do you tell what gender it is?
Bugscope Team male palps are larger, usually, like boxing gloves, whereas these are small (the things that resemble limbs on either side of the mouth)
- Teacher Can me move down to the abdomen/
Bugscope Team Are you able to click on the image?
Bugscope Team Just click on a point to move down, and it should put the point you click into the center of the next picture. Scott is moving for you now.
Bugscope Team If that isn't working for you, please let us know. Each time web browsers get updated, we need to revisit things because some things stop working.
- Bugscope Team spiders can sense when venom (from another spider, for example) has entered a particular limb, and they can selectively autotomize that limb
- Bugscope Team if these are gonopores they are actually on the abdomen, not the cephalothorax
- Teacher Ok, thanks
- Teacher It seems to move the image up, not down when I click on it.
Bugscope Team it is set up to center wherever you click, so it could move up
Bugscope Team It depends on where you click. It isn't like swiping on a smartphone. If you click in the upper right corner, what is in that corner will be in the center. If you click in the middle at the top, the image moves down. We're using the idea of "click to center".
Bugscope Team Correction: it is sort of like swiping on a smartphone, only you can't drag them image (yet).
- Bugscope Team the cephalothorax is hardened, whereas the abdomen is soft, so if we do not critical point dry the spider from ethanol, the abdomen will shrivel up
- Bugscope Team To see the other specimens we have for you, you can click on the blue circle with the left-pointing arrow. This should slide the presets into view. You just click on one of the presets to jump to that spot. (Of course you can stay on the spider as long as you want!!)
- Bugscope Team Nice! The assassin bug's eye!
- Bugscope Team assassin bug compound eye
- Bugscope Team It is surrounded by lots of tiny "hairs" we call setae.
- Bugscope Team you can see the individual facets -- the ommatidia
- Bugscope Team And, there appear to be little lumps of dust on the eye, too.
- Bugscope Team If you take the magnification down (by clicking on the red "-" by the word Magnification) you can see most or possibly all of the head.
- Teacher Are the hairs around the eye purely sensory?
Bugscope Team most of those hairs are for sense of touch, yes
Bugscope Team some of them are what are called the 'vestiture,' which might help with identification of like species, for example
- Bugscope Team they feed similar to the way spiders do
- Bugscope Team they inject venom that dissolves the insides of their prey so they can suck it all up like a protein shake
- Teacher What do they primarily feed on/
Bugscope Team any smaller insects it can grab. not sure if it likes certain ones more
Bugscope Team They will try to attack just about anything that moves - though they're only successful with other insects. There was a large one on the frame of a door I was trying to walk through and it kept eyeing me and extending its proboscis like it want to eat me. I guess it figured if it could get me, it was set for life!
Bugscope Team taking care of the family, on into the future
- Bugscope Team they are 'true bugs,' and one of the criteria for that is the piercing/sucking mouthparts, like those of a stinkbug, for example
- Teacher How big can these insects get?
Bugscope Team The assassin bug that tried to attack me (well, that sat on the door and eyed me greedily) was approximately 1 inch (2.5cm) long, not counting its proboscis.
- Bugscope Team wheelbugs, for example, are another type of assassin bugs -- the kind that look kind of like a stegosaurus slash insect
- Bugscope Team they can be a couple of inches long no problem, even here in Illinois]
- Teacher Wouldn't want to encounter a larger one! Especially if they think they can take us on?
Bugscope Team yeah they are kind of cranky
Bugscope Team hahaha! Their bite can be painful and dangerous for people who have allergic reactions to stings and the like. My assassin bug was one of the "wheelbugs" that Scott mentions, and looking at pictures of it from my phone, I'd say it was actually a bit longer than an inch, maybe 1.25-1.5 inches.
- Teacher How many different species of assassin bugs are there?
Bugscope Team there are said to be about 7000 species in about 1000 genera
- Bugscope Team some ants have very few ommatidia -- you can easily count them, like twelve, for example
- Bugscope Team this one has a lot. some ants do not bother to have eyes at all
- Bugscope Team they communicate and respond to chemical signals, which seem to have the highest priority
- Bugscope Team so for example if you brushed the scent of a dead ant onto a live one, the scavenger ants that clean up the next will take that live ant away even if it is struggling
- Bugscope Team cool how the facets are scarred up
Bugscope Team it was either in some fights, or it was rolled around a bit after it died
- Bugscope Team they seem to be more like crystals in some species, whereas in other species they have fine features -- as in the moth ommatidia in another preset today
- Bugscope Team they can also get caught in death spirals, in which they follow a scent, like a food scent, in a circle until they die of exhaustion
Bugscope Team Processionary caterpillars will do this too.

- Bugscope Team Are things stuck?
- Bugscope Team here are moth ommatidia, for comparison
- Bugscope Team we think that the tiny dots, which are on the nanoscale, help direct the light into the ommatidium and thus into the visual portion of the brain
- Bugscope Team this is something else kind of cool we wanted you to see
- Bugscope Team Nice wing scale
- Bugscope Team we're pretty close up on a single moth scale
- Bugscope Team yes this is from the same moth as is on the stub
- Bugscope Team the roughly horizontally oriented lines are ridges in the scale, and their spacing interferes with the wavelengths of visible light, producing what are called structural colors
Bugscope Team One note on this, most blue colors on butterflies are structural, not due to pigments.
- Bugscope Team somewhere recently I read that almost all of the blue in nature is structural
- Bugscope Team Mrs. Haworth, are you still there? Do you need some help?
- Bugscope Team was there a mutiny or some sort of uprising?
- Bugscope Team Mrs Haworth we're going to shut down soon...
