Biologists hypothesize that the larvae of New Zealand glowworm Arachnocampa luminosa – which dangle, numerous and luminous, from the ceilings of caves – have evolved to resemble a star-studded night sky.

The ersatz starscape is thought to fool insects into thinking that the ceiling above them is no ceiling at all, but rather a vast and empty firmament. The insects move upward, buzzing freely through what they think is open sky, only to find themselves trapped in the sticky snare of a hungry glowworm.
