Scorpions, spiders, and different creatures that glow at the hours of darkness

The sight of a scorpion would possibly make some folks nervous, however Javier Aznar González de Rueda sees solely an ideal muse for his digital camera. The Madrid-based photographer has spent years documenting bugs that shine—and just about all scorpions fluoresce when uncovered to ultraviolet gentle due to particular substances of their exoskeletons that react to high-energy rays. Fluorescence is widespread in bugs and arachnids. Why that’s the case, although, is a thriller. Scientists have hypotheses: It would possibly assist with camouflage, signaling to mates, or solar safety. But laborious proof is scarce.

During night time walks, Aznar scouts for his multi-legged fashions, scanning the bottom with a UV flashlight for telltale pops of neon. To get one of the best photographs, he modified a pair of off-camera flashes to emit UV gentle, which, he says, “shows us the world in a different way.” The ensuing portraits reveal what’s hidden: dun-colored scorpions glowing aquamarine, caterpillars with smooth hairs, and bugs with vibrant spots that match their environment. Aznar hopes his pictures will encourage extra analysis into the position fluorescence performs in nature. Already, they’re displaying a facet of those creatures we’d by no means see in any other case.
