BIOLOGY
Food
Psychodinae: larvae feed on algae, fungi and bacteria in sewage and organic sludge; adults feed in polluted water and on flower nectar. Phlebotominae: adult females in three genera suck blood from humans or reptiles in subtropical and tropical regions; larvae feed on dead organic matter in habitats mentioned above.
Habitat
Moth flies (Psychodinae): adults often found around sewage installations, in public washrooms, and bathrooms in homes, and are attracted to light; larvae live in organic sludge that forms on inner surfaces of drains and sewage pipes; pupae occur on the surface of the organic film that the larvae have been living in. Sand flies (Phlebotominae): adults occur in a wide range of habitats but often near water in dry semi-arid areas in the Old World, and in tropical forests and savannas in the New World; larvae inhabit areas containing high levels of organic matter such as in animal burrows, termite hills, tree holes, and leaf litter.
Active Period
Spring through fall; all year in tropical and subtropical areas.
Development
Psychodinae: in the home, females lay irregular masses of 30-200 eggs in the organic gelatinous film lining drains, particularly in bathtubs and showers; eggs hatch 32-48 hours after being laid, when ambient temperatures are 70?F (about 20?C), and larvae pupate 9-15 days later; pupa stage lasts 20-40 hours; development time from egg to adult is 7-28 days, depending on temperature and food availability; adults live for about two weeks.
Range
Most of the world; more common and diverse in tropical regions
Distribution
Worldwide.
