- Bugscope Team we are ready to roll
- Bugscope Team hi Buggy!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team please let us know when you have questions for us
- Guest We are so excited.
- Bugscope Team Yay! Are you with the Altamont School?
- Bugscope Team this is a fruit fly
- Guest No. We are in Louisiana
Bugscope Team Awesome!
- Bugscope Team see the compound eyes?
- Bugscope Team they're a little dried, slightly collapsed
- Bugscope Team toward the middle of the head, and up, we see the antennae, like little pads
- Bugscope Team and the mouthparts are on the lower portion of the face
- Bugscope Team Buggy we just set it up so you can drive, until the school logs in.
- Bugscope Team if you click on the screen, the 'scope will center where you clicked
- Bugscope Team and if you click on one of the presets, on the lefthand screen, the 'scope will drive to that place on the stub
- Bugscope Team let us know if you have any problems driving and for sure let us know as well if you have questions, about anything.
- Bugscope Team Hello Bea's Bunch!
- Bugscope Team Please feel free to ask us questions, about anything.
- Bugscope Team now we see the forelimbs, and a wing on the left
- Bugscope Team awesome!
- Bugscope Team we can see the two segments of the claw, and the frilly part in between that helps the fly stick to surfaces
- Bugscope Team honeybee face
- Guest Will you show us the stinger?
- Bugscope Team the two long things are halves of the labrum, which protects the tongue
- Guest looks like teeth?
Bugscope Team those are hardened chitin, and below them is the tongue, called a glossa
- Guest It looks like a serrated knife!
Bugscope Team yes it does, exactically!
- Bugscope Team sometimes we can see more clearly that the two sides slide, side by side, to cut better into what they're stinging
- Bugscope Team this is a male mosquito
- Bugscope Team we can tell, without a microscope, which ones are males
- Guest It looks like a Dr. Seuss character
- Bugscope Team stingers are modified ovipositors, and some insects use them to both sting and deliver eggs
Bugscope Team This, in combination with the fact that honey bee stingers are serrated, is the reason why honeybees die after stinging. Their sting gets stuck in the "stingees" tissue and when the honeybee goes to pull it out, she rips her reproductive system out of her abdomen and bleeds to death
- Bugscope Team when honeybees sting mammals, their stingers get stuck and cannot be pulled easily out of our thick skin
- Bugscope Team but they can sting other insects no problem
- Bugscope Team male mosquitoes have these beautiful frilly antennae, whereas those of the females are kind of dull, in comparison
Bugscope Team The frills provide the mosquito with more surface area for chemoreceptors to smell better, and allow male mosquitos to better sense the wingbeats of female mosquitos
- Bugscope Team mosquitoes have tiny scales on the surfaces of much of their exoskeleton, like moths and butterflies and silverfish
Bugscope Team the tiny scales are kind of like feathers and may have a similar function, but one of their main functions is that they help protect those insects that have them from getting caught in spiderwebs
- Guest What happens to the other insects when they get stung?
Bugscope Team I think likely it kills them, or most of them
Bugscope Team Do you mean stung as in a wasp stinging other insects or biten as in a mosquito biting another insect?
- Bugscope Team when honeybees sting other insects it is comparable to wasp sting, which can be done repeatedly, even with mammals
- Bugscope Team tick leaning on a log
- Guest do all ticks carry lyme disease?
- Guest wasp sting
Bugscope Team Well wasps actually frequently "sting" caterpillars. I put "sting" in " because the wasps aren't doing the stinging for defense they are actually laying their eggs in the caterpillar when they sting them
Bugscope Team If you've ever seen the movie Alien - it's kinda like that
Bugscope Team The wasp eggs sit inside of the caterpillar growing and when they are ready to pupate they burrow out of the caterpillar and cocoon on their body
Bugscope Team Social wasps will also sting caterpillars, which they then chew up and feed to their larvae. The social wasps are the ones you are probably most familiar with. Many of the parasitic wasps mentioned above are super tiny and easily overlooked by the casual observer
Bugscope Team This stinging is again not for defense, but is a bit closer to actual stinging than parasitic wasps laying eggs
- Bugscope Team ticks start out with six legs and then metamorphose into adult stages, with eight legs
Bugscope Team Some tick can transmit diseases between other animals and humans, like Lyme disease and Rocky Mountain Spotted Fever. Some ticks also have venomous saliva which can induce paralysis in their hosts
- Bugscope Team This tick looks to me like is the Lone Star Tick
- Bugscope Team the part facing us helps the tick keep this central portion of its head stuck into your skin
- Bugscope Team at the very top of the image we see now, there's a portion of the mouthparts that rasps against your skin so it can cut into it and get blood back out
- Bugscope Team this is the part of the hypostome -- the part that sticks beneath your skin like a hypodermic needle -- that rasps
- Guest Does that mean it is from Texas?
Bugscope Team Nope! although it could be. The lonestar tick can be found over much of the eastern half of the united states. It gets its name from a white star shaped dot on its back. And maybe whoever named it was from Texas and made the association? not sure about that part, but I suppose its possible
- Bugscope Team earlier, further down on the body, we found features like these that resemble red blood cells
- Bugscope Team we are always looking for red blood cells on ticks. they're usually 8 to 10 microns in diameter and may be shrunken as well.
- Guest What is the hole?
Bugscope Team that very round hole was from a pin; the stinkbug had been mounted for someone's collection
- Bugscope Team the smaller hole was an opening of the stink gland on the stinkbug's right side
Bugscope Team Some stink bugs emit a smell that is similar to coriander
- Bugscope Team this is the absorbent area of the cuticle around the opening of the stink gland on the left side
- Bugscope Team Luke I am your Uncle, the stinkbug.
- Bugscope Team see its compound eyes, on either side of its head?
- Bugscope Team stinkbugs are said to be repelled by, or at least understand the repulsion produced by, their own bad smell
Bugscope Team I kind of enjoy the stink bug smell to be honest. It reminds me of green apple jolly ranchers...
Bugscope Team But I bet it doesn't TASTE like green apple jolly ranchers...
- Bugscope Team please, everyone, feel free to ask us questions about what you see or how this all works
- Bugscope Team you can see that a stink bug is in fact a true bug - this is because they have a piercing sucking mouthpart - aka the long tube that you can partially see between the yes
- Bugscope Team eyes*
- Bugscope Team the mottled features we see are likely more due to the stinkbug decaying/rotting
- Guest What do they eat?
Bugscope Team The puncture various parts of plants with their tube like mouthparts and drink plant juices
Bugscope Team Many cause damage to crops like apples
Bugscope Team Some stink bugs are also predators. They jab their beak into other insects and drink their juices.
Bugscope Team usually when 'true' bugs like that are predators, they have a three-piece proboscis, and the rostrum (the beak part) is super hard and pointy
- Guest Where do they lay their eggs?
Bugscope Team They try to lay their eggs on or near their host plants
Bugscope Team I'm not 100% sure, but I imagine predacious ones would lay their eggs where the female feels the young will find prey
- Bugscope Team this is one of the raptorial forelimbs of the praying mantis; the tooth-like elements we see are used to help grip the mantis's prey
- Bugscope Team Does anyone know if the "teeth" also function as mechanoreceptors of some kind, perhaps pressure sensors?
Bugscope Team I bet some of them are equipped as mechanoreceptors.
- Bugscope Team these looked like scratches on the surface of the compound eye, but we can see that they are strands of fungus -- fungal hyphae
- Bugscope Team Nice hamuli.
- Bugscope Team The velcro of the bee world.
- Guest I can see that.
- Bugscope Team here, now, we are looking at the hooks, called hamuli, as Daniel says, that help honeybees and wasps and other bees hold their fore- and hindwings together when they fly
- Guest What are hamuli?
Bugscope Team They actually act like velcro, though I'm sure one of the true entomologists here can give a better explanation. They're used to hold the pairs of bee wings together during flight.
Bugscope Team They basically zip the wings together.
Bugscope Team hamuli are not exclusive to bees, most wasps, bees and ants have them. Similar structures also exist in moths, although I can never remember what they are called...
- Bugscope Team bees and wasps have four wings, and it is more efficient for them to fly with essentially two wings, so they clip them together when they fly
Bugscope Team Across insect groups we typically see either a fusion of hind and forewings, or a loss in flight function in one pair of wings, for the reason that Scott mentioned.
Bugscope Team flies for example have reduced hind wings called halteres, which function as flight stabilizers rather than as flapping wings
Bugscope Team beetles have modified forewings called elytra which act as a shell that protects them and only use their hind wings for powered flight
- Guest Ms. Brabham and Ms. Lavergne's classes- Do you have any questions you would like to ask the scientists?
- Bugscope Team Bea's Bunch we really appreciate your, and everyone else's, connecting with us today. Our scheduled school did not show up.
- Bugscope Team You are always welcome to log on as guests when we're doing this -- usually twice a week during the season (about 9 months), and fewer times outside of the season.
- Bugscope Team you are of course also welcome to apply for sessions specifically set up for your school
- Bugscope Team time for us to go...
- Bugscope Team Thank you, Everyone!
- Bugscope Team Logging off!
