Glow worms mimic stars, creating a stunning faux night sky in a New Zealand cave

Some insects deceive predators or lure prey by mimicking the appearance of others. Glow worms in the Waitomo Caves of New Zealand have a more creative approach: they mimic stars, collaborating to disorient and prey on moths that use light in the night sky to navigate. Part of KQED’s science documentary series Deep Look, this luminous short provides a fascinating glimpse of one of nature’s most unusual – and inventive – predators.
