![]() * C heck your home and room bedding before sleeping for scorpions. Safety Scorpion Hunting with Black Lights. It has been noted that even fossils can fluoresce despite being preserved for millions of years. We have a scorpion inside an acrylic and it still fluoresces under UV light. Scorpions can be preserved in various mediums and still glow under black light. In this case the glowing property is part of the body and not controllable through animal function. THIS IS THE MASTER SCORPION hunter for sure.ĭo not be confused with other bio-luminescent animals that can glow by creating photons of energy through a chemical process.

The scene was lighted with a red light, showing again that the babies do not glow under UV light. #8 Another old picture of a scorpion with babies. That’s probably why the babies do not glow. As mentioned earlier, the chemical causing the glow accumulates on mature exoskeletons. Without the UV light, it would appear completely black. #5 Different scorpions glow as well! Possibly Hemiscorpiidae, Liocheles australasiae. #4 The same pair lighted with only UV light. ![]() #3 A pair of scorpions on the tree bark, again with fill flash #2 Same composition, but purely lit by UV light This Lychas scutilus is quite commonly found in Singapore. #1 Had everyone practising UV shots with my UV torch, this shot used flash to fill the background. Update : My UV photos were recently published on WIRED, with more details on this phenomenon: The Secret World of Fluorescent Arthropods. If it requires to move in the day for any reason, this might help to re-radiate solar energy from the sun.Īs for HOW the glow came about, further scouring found that the mature exoskeleton accumulates a chemical called beta-carboline, which glows under UV. Scorpions normally hunt at night and are tuned for the light and temperature conditions. There is another theory that the nocturnal scorpions have properties in it’s exoskeleton that repels UV light, protecting it from the sun. Douglas Gaffin of the University of Oklahoma “blindfolded” the scorpions and found that they could still detect light. It is believed to be used by the scorpions to detect shelter, as being under shelter would block the light signals on it’s body. But few know why or how.Īfter scouring around for answers, the most commonly accepted answer was… that the scorpion’s cuticle or exoskeleton functions as a giant secondary eye, collecting light information and relaying it to the nervous system. Many macro shooters have come to know that the scorpion’s exoskeleton glows a bright cyan under Ultra Violet (UV) light. ![]()
