Waitomo Glow Worm Cave
Spent the day traveling through the beautiful New Zealand countryside from Rotorua to Auckland. Our late morning stop was at the Waitomo glowworm caves.
The first part of the cave was a traditional cave with stalactites and stalagmites. Then we boarded a small boat on the river that went through the cave. As we moved along the river, we could see the glowworm threads hanging from the walls and ceiling. It almost looked like bright stars against a dark sky.
Glowworms, which are really insect larvae, attach to rock and send out tiny threads that they use to catch other insects. They use bioluminescence to make the threads glow to attract their prey.
