One bizarre and unique feature of the Waitomo caves are the glowworms, (in Spec, p-Arachnocampa) quite similar to the RL glowworms of the same cave system. p-Archnocampa can be found in other caves, but glowworm populations are unusually dense in Waitomo. Also know as fungus gnats, these hardy insects can be found on the ceiling and walls, but from a human's point of view, these nondescript adults pale in comparison to their children..
