Keroplatidae
Predatory Fungus Gnats, Fungus Gnats
Keroplatidae is a family of small, delicate flies in the order Diptera, commonly known as predatory fungus gnats. The family comprises approximately 950 described species, though true diversity is estimated to be substantially higher. Members are predominantly forest-dwelling insects associated with damp microhabitats where fungi occur. The family is notable for containing three genera—Arachnocampa, Orfelia, and Keroplatus—with bioluminescent larvae, commonly called "glowworms." Larval ecology varies: some feed on fungi, others are predatory, and many combine both strategies. The fossil record extends to the Cretaceous period.
