This is the frog-legged leaf beetle, and there’s a good chance those gigantic legs are his weapons, researchers suspect. Found in the jungles of Southeast Asia, this brightly coloured, iridescent species can grow up to 5 cm long. Unlike its namesake, it doesn’t use its hind legs for jumping, but for clinging onto stems and foliage while it eats. Now researchers think that males also use them for wrestling other rivals.
