Identification:  The adult Fungus Gnat is mosquito-like in appearance. The larvae construct protective shelters along several with long thin silk threads with sticky globules on them. The light of the Glow worms is produced by two light-producing organs found on the end of the larvae.

Habitat: 

Feeding: The sticky threads that the larvae produce are used to capture small insects which are attracted to light given off by the glow worms. When an insect is captured it is hauled up the line and consumed. Glow worms are not particular about their prey, they have been known to consume adult Fungus Gnats that have become entangled in their threads.

Breeding/Nesting: After mating the Fungus Gnat lays eggs on the walls and ceilings of caves, ledges or sheltered earth banks. Three weeks later the larvae hatch and consume eggs and other larvae to obtain nourishment.
