- Bugscope Team sample is pumping down
- Bugscope Team we are ready to roll
- Bugscope Team :(
- Bugscope Team making presets for today's session
- Bugscope Team we are ready to roll
- Bugscope Team godd morning!
- Bugscope Team Welcome to Bugscope!
- Teacher we are just making sure we can connect.
- Bugscope Team d'oh sorry "good" morning
- Bugscope Team cool we will be here
- Bugscope Team we always start an hour early so we can make the presets
- Teacher we are here
- Bugscope Team hi! welcome!
- Bugscope Team we are currently looking at a grasshopper head
- Bugscope Team to the left is a very big compound eye
- Teacher what kind of grass hopper?
- Teacher there are lots of species in southern Alberta Canada
- Bugscope Team I'm not sure what kind of grasshopper it is -- it was collected here, like a lubber or something, not sure
- Teacher cool
- Teacher so if we click the image, we can move the microscope?
- Bugscope Team likely it's a common field grasshopper
- Teacher we have many around here.
- Bugscope Team this is a small one -- all of the insects have to fit on a 1.75-in. diameter stub
- Bugscope Team you can click to center, and you can change mag, so if you click on an edge at a low mag you can essentially move in whatever direction you want
- Bugscope Team we used to have a click to move capability, but remotely it is hard to tell if you're moving or not
- Bugscope Team you can of course click on any of the presets, on the lefthand screen, to get the microscope to move to one of those positions on the stub
- Bugscope Team please let us know if something does not work
- Bugscope Team once in a while the 'scope will keep driving to one place no matter what you do
- Teacher can we drive to its wings
- Teacher it looks scary up close!
- Bugscope Team yes but they are folded...
- Bugscope Team now you can see the large hindleg and the folded wing
- Teacher huge leg!
- Bugscope Team insects have hairs all over them to help them feel what is going on
- Bugscope Team here you can see the mouthparts
Bugscope Team the appendage looking like things are palps that help it manoeuver food around and also gustatory senses (taste)
- Teacher do they breathe through pores?
Bugscope Team yes. there are ports along their bodies that are connected to a trachea. The trachea transports the oxygen
- Bugscope Team this is a fruitfly
- Bugscope Team its head fell off at some point
- Bugscope Team maybe Joe has; I've never eaten insects on purpose
- Bugscope Team haha sj
- Teacher no wonder they are so hard to catch with all of those sensors
- Teacher have you ever eaten a grasshopper?
Bugscope Team not a grasshopper. but crickets, and they're not too bad.
- Bugscope Team flies taste like paper
- Teacher We have accidentally eaten a few too
- Bugscope Team any time you eat broccoli, you're probably eating a lot of insects
- Bugscope Team you can look at other stuff on the stub today, if you want; we set up a different set of insects/arthropods each time we do this
- Bugscope Team it might taste better with chocolate or cheese
- Teacher how do we do that
Bugscope Team click on one of the presets on the lefthand screen
- Teacher my name is kingi i ate one , I roasted it with a magnifying glass
Bugscope Team haha poor grasshopper
- Teacher gross
- Bugscope Team the background in all of these views is carbon doublestick tape
- Bugscope Team the specimens are all coated with gold-palladium to make them conductive
- Teacher did you catch all of these bugs?
Bugscope Team some of them we caught and some of them other people caught and sent or brought them to us
- Bugscope Team the fruitfly that we made into a preset came from down here
- Bugscope Team in the Underworld, where we work
- Bugscope Team you can see the beetle's compound eyes, and its antennae, and a fringe that helps it know when it is moving its head
- Teacher it has an interesting mouth
- Bugscope Team this isn't the mouth. the mouth is to the north a little bit
- Bugscope Team this is where the head is attached to the thorax
- Teacher ohhhhhhh
- Bugscope Team click beetles are called that because they have an escape mechanism, where they can pop themselves up into the air
- Teacher does it have pinchers?
Bugscope Team their claws are kind of like pinchers, and their mouthparts -- the mandibles --are like pinchers as well
- Bugscope Team right now we're looking at the mandibular and maxillary palps
- Teacher do they bite people?
- Bugscope Team they might bite in self defense
- Bugscope Team palps are accessory mouthparts that help taste and maneuver food into the mouth, as Joe had said below
- Bugscope Team click beetles click in self-defense as well, like if you lean on one it will pop against your back
- Bugscope Team these are wing scales
- Teacher we are looking at the butterfly wing
- Teacher we grew butterfies once... they were painted lady butterflys
- Bugscope Team butterflies, moths, silverfish, mosquitoes, and few other insects have scales
- Bugscope Team those seem to be pretty common for classes to grow. maybe they are extra hardy?
- Bugscope Team scales are modified setae, and one of their purposes is to protect the insect from spiderwebs
- Bugscope Team these are butterfly scales, and the way that they are grooved determines the colours you see (in part)
Bugscope Team these grooves reflect and refract light giving off the colours you see, and they may also contain colours in them as well
- Bugscope Team as Joe says, butterflies and moths, especially, can have both structural colors and colors derived from pigment
- Teacher we didn't know that mosquitoes had scales
- Teacher we wondered about the patterns on a butterdly wing
Bugscope Team some butterflies that look exactly alike to us do not look at all the same to another insect because they reflect or refract colors in the UV range of light that we do not see
- Teacher that is amazing
- Bugscope Team sometimes we see pigment granules in the little holes we can see now
- Teacher there is a lot of math ...things to count when you look close up!
- Teacher what do you have to do to the insects to make them ready to view?
Bugscope Team we stick them only aluminum disks that fit into the microscope. The disks have carbon tape, but we also use a dab of silver paint to help glue them on better and to help ground any extra charge. Then we coat everything with gold/palladium alloy to make them conductive for the electrons
- Bugscope Team you can get an idea of the size of the specimens/features by comparing it with the data bar at the bottom left of the screen
- Teacher ants are creepy looking
Bugscope Team ants are almost all females
- Bugscope Team all the workers are female.
- Bugscope Team the same is true for bees
- Bugscope Team if you see a flying ant it is either queen, out for a cruise, or a male ant
- Bugscope Team and wasps. ants and wasps and bees are related
- Bugscope Team when they have wings, they have four wings, compared to a fly, which has only two
- Bugscope Team the abdomen of an ant, as we see here, is called a 'gaster'
- Teacher that is very interesting
- Bugscope Team sometimes we find a tiny stinger at the tip of the gaster
- Teacher theyare so strong
- Bugscope Team you can see where the antenna fits into the head with a ball and socket joint
Bugscope Team ants have very good chemosensors, they rely on chemicals to find food, and recognize nest mates and who their queen is
Bugscope Team if a worker ant somehow gains the ability to reproduce (workers usually will not have this ability), they will be attacked by nest mates because of changes in their chemical profile.
- Teacher ewwwwww
- Teacher we want to check out the lady bug
- Bugscope Team a lovely baby ladybug
- Bugscope Team so cute!
- Bugscope Team this is what they look like before they metamorphose into their adult form
- Bugscope Team you can see the palps
- Teacher it looks like it is smiling
- Bugscope Team larval insects (caterpillars) often have five or so small eyes per side of the head
- Teacher how long does it take them to change to an adult?
Bugscope Team egg to adult is roughly 3 weeks or so depending on species
- Bugscope Team they spend a couple of weeks eating and then change into cute little spotted beetles
- Teacher sometimes they stay in our windows over the winter...
- Bugscope Team yes they do that here too
- Teacher between the window sill and the frame
- Teacher how many wings do they have?
Bugscope Team beetles all have 4 wings, 2 of which are for flight, and the other 2 have been modified into a hard shell called the elytra
Bugscope Team the elytra acts as an air foil of sorts
Bugscope Team *airfoil
- Teacher yikes!
- Bugscope Team fruitfly
- Teacher we have some in our home on occasion!
- Bugscope Team fruitflies and many other flying insects have an extra three eyes on the tops of their heads
- Bugscope Team currently we are sharing the lab with a number of fruitflies
- Bugscope Team someone's experiment went feral
- Teacher why are some fruit flys red?
Bugscope Team they have a large variety of eye colors and other mutations
- Teacher my grandma catches them with a tall jar with a yeast mixture in it.
Bugscope Team that's what we should do here
- Teacher :(
- Bugscope Team I am not sure what purpose a different eye color would serve, except to identify the fruitfly to potential mates
Bugscope Team color in they eyes play a number of roles, they can restore photoconverted visual pigments, and in some cases, they fine-tune their spectral sensitivity
- Teacher well, thank you for all of the very interesting information.
- Bugscope Team thank you for connecting with us today!
- Bugscope Team Sorry we missed you a couple days ago
- Bugscope Team Thank you!
- Bugscope Team thanks!
- Bugscope Team have a good weekend!
- Teacher it was our fault. how often do you offer these sessions?
- Teacher we will watch out for bugs!
- Bugscope Team usually we run bugscope about 2 times a week. You are always welcome to sign up again in the future
- Bugscope Team yes!
- Teacher we have a little zoomy microscope for our computer but this is way more cool!
- Bugscope Team here you can see the inside of the microscope
- Teacher neat!
- Bugscope Team I just vented it, so we will be able to open the door soon
- Bugscope Team you can see the insects we were just looking at
- Teacher have fun catching those fruit flies!!!
Bugscope Team haha Thank you!
- Bugscope Team Bye!
