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. The species can be found near sewer drains, sewage treatment plants, plant pots, swamps and any other shaded place containing decaying, moist organic matter. The species is a common pest around household drains, but the larvae have an important role in sewage treatment.
Clogmia albipunctata adults have broad wings covered with brownish and blackish hairs. There is a tuft of blackish hair near each wing vein fork and a tuft of white hair at the ends of most veins (i.e. each wing has a pair of black spots near the middle and several white spots along the edge). The thorax and abdomen are covered in gray/brownish-gray hairs. There is a pair of antennae which are longer than the abdomen and covered in white hairs. The legs are brown with white annuli (rings) at the tips of the tibiae and metatarsi.
The original species description gives a body length of 2.2 mm and a wing length... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bathroom Moth Fly is recorded against all the insects logged in Great Smoky Mountains National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
