The Waitomo Caves

Limestone caves on New Zealand's North Island whose ceilings glow with the larvae of Arachnocampa luminosa, a species found nowhere else. Thousands of blue points above an underground river look like a night sky; they are in fact lures for prey the larvae catch on sticky threads. Māori knew the caves long before Europeans, and the chief Tāne Tinorau led the first survey into them in 1887.
