Glow Worm Caves in New Zealand

Strange carnivorous worms glow and twinkle like the night sky to attract their prey.

New Zealand’s famous glowworms are one of the many wonders this beautiful country has to offer. What makes these creatures so unique is their bioluminescent glow that illuminates many caves across New Zealand.

Technically, these glowworms aren’t actually worms. They are the larvae of a special kind of fly known as a fungus gnat whose tail glows with a blue-green light provided by an organ equivalent to a human kidney. This light is used to attract its prey into a snare of sticky threads, but when scattered across the ceiling of a cave resemble a star-filled sky.
