Clogmia albipunctata

Clogmia albipunctata is a species of drain fly, a member of the family Psychodidae commonly known as the bathroom moth midge, bathroom moth fly or drain fly. This very common species has a worldwide distribution in tropical and temperate areas and is often associated with humans. Clogmia albipunctata can reach a length of 3–5 millimetres (0.12–0.20 in). Both the body and the wings are covered with thick gray-brown hair. The wings are pointed, and have some white spots (hence the Latin species name). Despite being a Diptera (a fly), it has a similar appearance to that of a small moth. The antennae show dense setae, each segment with separate whorls. The adults do not feed and live for about 12 days. They spend most of their life perched on walls. They move rarely, and with weak flight. The larvae live in aquatic environments, feeding on organic decaying matter, and take about 18 days to turn into a pupa, which develops into an adult after 5 days. They often infest drains of bathrooms and, for this reason, they are also known as 'bath flies' in the United States. Although they are considered harmless, some cases of myiasis caused by the larvae of this insect are reported in the literature, at the nasal, intestinal and urinary levels but are often associated with very poor sanitary conditions and bad hygiene habits.
