a family of insects of the order Diptera. Tiny gnats (1–4 mm long). About 450 species.
Psychodidae are widespread throughout the world; in the USSR there are several dozen species, mostly in the south. The larvae live in rotting plant residues, sometimes in water. Larvae of blood-sucking species (mosquitoes) live in cracks in the soil, clay walls, rodent holes, and so on. Some species (for example, Phlebotomus papatasii) transmit the causative agents of diseases—phlebotomus fever and skin leishmaniasis.
