Glowworm Caves in WaitomoIn the Waitomo region of New Zealand, there is an underground labrynth of caves that have been forming over the last 30 million years. And in one of these caverns is a very special animal – one that has evolved to thrive in wind-free places exactly like these caverns. The species is Arachnocampa luminosa, a species of fungus gnat that is luminous during the larval stage. When a person travels by boat or inner tube through the pitch black Glowworm Grotto, as the cavern is called, the ceiling looks like a galaxy of blue stars.
Hi! I have a biology question for you. Its believed that many animals use bioluminescence to attract prey. I believe that works for insects, deep sea animals and stuff. But why then didn't those animals eventually evolve the instinct to avoid lights instead of going after them?
