Living Stars in Limestone Caves

Waitomo, in the King Country of New Zealand's North Island, is known for limestone caves whose ceilings glitter with thousands of glowworms. The name comes from Maori words meaning water passing through a hole, after the streams that carved the caves.

The glowworms are the larvae of a fungus gnat, Arachnocampa luminosa. Each larva hangs sticky silk threads from the ceiling and glows by bioluminescence to lure insects into the trap. Adult flies live only a few days, as they have no mouths to eat, and exist only to breed.

Local chief Tane Tinorau and English surveyor Fred Mace explored the main cave in 1887, and Tinorau's descendants still help run it. Visitors drift by boat through the Glowworm Grotto in silence, while black water rafting, started in 1987, floats adventurers through caves on inner tubes.
