The Glowing Spider-Worms of New Zealand
For over one hundred years, millions of tourists have flocked to the ancient limestone Waitomo Caves on New Zealand’s North Island, where a stunning species of fungus gnat called Arachnocampa luminosa live.
Unique to New Zealand and Australia, they are found in caves, grottoes, and other sheltered places. Arachnocampa means ‘spider-worm,’ as the gnat is known for the way their larvae hang strong vertical silk threads from their underground habitats. Since the larvae are luminescent, the thousands of tiny threads light up cave ceilings like a starry sky.
