Scorpion glow in blacklight9/12/2023 ![]() The female usually gives birth to anywhere from 25 to 35 young. In the Chalcraft lab, the technique for that was that when a rainy night came on, we grad students would drive the country roads with the car windows open, listening for the calls.A female Arizona bark scorpion with youngĪrizona bark scorpions have a gestation period of several months, are born live, and are gently guided onto their mother's back. When I was a graduate student, I needed frog and toad eggs for my experiment. Still, that’s how I got my Mountain Mullet observation and my Yellow Nose Shrimp observation. If the stream is somewhat deeper, it is actually more challenging, because then I can’t maintain my position as well – I’m either drifting on the current or swimming. Then I put it under a digital microscope.īut what I have been doing even longer than that is “fish watching” by putting on a mask and snorkel and lying belly down in a shallow stream, where the water is just deep enough to cover my mask in that prone position. My one Cyanobacteria observation and freshwater Green Algae observation was made by collecting creek water in a jar and growing out an ecosphere (inspired by the Jartopia YouTube channel) until I could see that there was some. His website also has an extensive library of NFCs for North American songbirds which is really useful in helping with identification (it’s basically a NFC field guide): A MacGyver I am not so that’s what I went with for my second setup. Bill Evans sells a kit on his website that is good quality and is a reasonable price for what it is but still costs a few hundred bucks. It wasn’t very sensitive but it picked some stuff up. My first setup was the mic from a pair of earbuds on a plate with plastic wrap over it inside a plastic flower pot, routed to my computer. A microphone, a weatherproof housing, something surrounding the mic to add directionality (reducing background noise), and something to record sounds, like a computer or other recorder. The basic idea around a NFC setup is very simple. I live in a forested area but have recorded rails, bitterns, night-herons, Common Terns, Common Goldeneye, and other neat stuff. I used to record nocturnal flight calls of birds migrating over my house at night. I believe most regular consumer UV lights are the safer longwave lights - but it’s worth observing the wavelength and recommended safety precautions if you you buy one. Note: shortwave UV light is pretty dangerous to look at and can burn skin, but different stuff reacts more to shortwave length lights. (I lent my lights to a friend who said she almost fainted when she saw all the stains low on the wall where her cats sprayed). I used black lights to see where my pets had accidents. Urine glows under a black light pest control sometimes use black lights to discover mouse or rat trails. I was surprised to discover dermatologists use a specific wavelength of UV light to diagnose ringworm (picked up volunteering for a pet rescue). US$ have a UV strip to foil counterfeiters (not single dollars, I think only higher denominations.) In a dark closet, the green liquid (chlorophyll) glowed blood red in UV light. We blended greens (usually tender weeds I had kids gather or spinach if I had a time crunch) with alcohol and then filtered the liquid through a coffee filter into little jars (or test tubes, if we were being fancy). I had an experiment where they discovered the chlorophyll in plants. (This showed kids that UV occurs in real sunlight, not just a lamp). Erik’s Deli pickles glowed, as do some spices.Ī jar of tonic water glows in strong sunlight (UV), but it’s not too noticeable unless you place it next to a jar of plain water against a black background. Shed snakeskins and fingernails glow, not brightly but enough. We also had some glowing minerals in the collections. We had scorpions in the nature center, so that was a hit. It was fascinating to see all the things we could do with black lights. ![]() Back in the day, I had a UV light class I developed for our after school science and summer science camp curriculum.
