![]() I was shocked at how 'bright' this drop-in was using 'bright' since I don't know what other word to describe the black-lightyness of this light. I installed the drop-in using the Sky-Ray S-R5 (which I just noticed Manafont has removed from their listings ). (The UV drop-ins on Manafont all have what appears to be the same emitter so they may be all the same except two have OP reflectors and the other two have SMO.) the 395nm of the 'generic' drop-in, and had more reviews that were all positive. ![]() I checked the selection of UV drop-ins on Manafont and selected this module. I was discussing this with a friend when we recalled that scorpions glow under a blacklight. ( ) I had caught 3-4 in traps, but I knew there were more around the yard. Although not deadly, the scorpions we have in Texas can inflict very painful stings, and are known to come indoors and hide under blankets or in other undesirable locations. ” The reasons Scorpions glow under black light is not fully understood, and this is an excellent posting for us to tag as a Mystery.Earlier this year, I moved to an area which I discovered is overrun with scorpions. In fact, mating is an extremely dangerous activity (to the smaller, usually male, partner). Scorpions hunt at night and gladly eat fellow scorpions. Maybe it helps the antisocial creatures locate each other in the dark and either stay away (usually) or find a mate. After hundreds of millions of years, after all other cuticle layers are lost, the hyaline layer remains, fossilized in rocks. The hylane skin toughens into an incredible substance. They glow bright green-blue or green-yellow like scorpion jewels. ![]() At night in the Arizona desert, you can see scorpions within a 20-foot radius by shining a black (ultraviolet) light around. ” According to AnswerBag: “All scorpions glow in the dark-even after death, even fossilized! A thin, transparent film (hyaline) in the outermost layer (cuticle) of their exoskeleton contains a protein that fluoresces. In volcanic habitats it can be quite dark with a striped tail. It has the basic identifiers of Paruroctonus scorpions, such as relatively robust hands and a somewhat slender metasoma/tail in which the keels do not terminate in an enlarged denticle. Throughout much of its range it is the only scorpion found. ” According to BugGuide, it is: “Highly variable throughout its range, and depending on habitat. If disturbed, they will inflict a sting that can cause painful swelling, but the poison of most North American species is not lethal to people. ENature has some information on the species, including: “Most scorpions are not dangerous and do not attack people. We suspect it is the Northern Scorpion, Paruroctonus boreus, which we determined upon locating a website with images of the Northern Scorpions photographed in Washington. ![]() Thanks for your wonderful image of a Scorpion glowing under black light. ![]() Signature: Paul Huffman, President-for-Life, Moclips Surf Club Northern Scorpion under Black Light Don’t know the exact species or the sting hazard, but it seems like a big tail, smallish pincher. I was surprised that these scorpions are fairly common on rocky arid ground around Yakima in Eastern Washington. Thought you should have some pictures of scorpion florescence under UV. ![]()
