The Waitomo Glowworm Caves attraction is a cave at Waitomo on the North Island of New Zealand, known for its population of glowworms, Arachnocampa luminosa. This species is found exclusively in New Zealand. And they for sure light the place up.
The caves began to form when earth movement caused the hard limestone to bend and buckle under the ocean and rise above the sea floor. As the rock was exposed to air, it separated and created cracks and weaknesses that allowed for water to flow through them dissolving the limestone and over time large caves were formed.
The stalactites, stalagmites, and other cave formations grew from water dripping from the ceiling or flowing over the walls and leaving behind limestone deposits. These stunning cave decorations take millions of years to form.
The glowworm is a species of fungus. Both the larval stage and the imago are luminescent. The species is known to dwell in wet places. Its Māori name is titiwai, meaning “projected over water”.
