Jumping Spiders Catch UV Light
Jumping spiders have recently attracted attention as the cutest of the spider family. But they have some downright odd habits. Male jumping spiders have patches of UV-reflective scales on their faces and bodies, which they show off when posturing during courtship. But the males aren’t the only ones who glow, females also have their glowing tricks to attract males, and that’s the fluorescence green in UV light. When UV light was blocked, spiders didn’t glow, and they lost interest in mating. It’s as if these psychedelic spiders are dressed for a rave. As the male gets closer to attracting their mate, they arch their body, vibrate, and tiptoe to their potential mate, eventually luring them in with their bright colors (NBC News).
