In a Glow Worm Cave In New Zealand Bioluminescent Worms Hang from Silk Threads

Glowworms are not worms but the larvae of fungus gnats, an insect that looks like a mosquito. There are two types of fungus gnats - those that feed on fungi like mushrooms and those that are carnivorous and feed on other smaller insects. The glowworms in New Zealand and Australia are the larvae of the carnivorous fungus gnats. www.teacherspayteachers.com/S...
In this video, we are in a boat in the limestone cave, and that is the rushing water you hear.
Beyond being pretty, the bioluminescent glow is also used to attract prey. Smaller insects and flies are drawn to the light and fly towards it.
