There are four species of fungus gnat in the genus Arachnocampa. They spend up to a year as larvae, then pupate into adult flies, mate, lay eggs and die. One species is known as the the New Zealand glowworm in its larval form. The caves inhabited by the glowworms have become a popular tourist attraction.

Recently developed image intensifier technology reveals their true nature.
Developed by Japanese TV company NHK, the image intensifier (II) system has a camera chip 300 times more powerful than the standard digibeta camera used for most wildlife filming. It took only LED headtorches to light the cave sufficiently to see the 'gloworms'. Previously, they'd been filmed using time-lapse which creates a flashing effect that doesn't actually occur.
Discover what these behaviours are and how different plants and animals use them.
