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 →

Rare
Under 5% of wildlife watchers report a Bathroom Moth Fly sighting in San Francisco on a given day, based on 174 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to November
In those months about 10% of wildlife watchers report a Bathroom Moth Fly in San Francisco on a given day, against under 5% in December to June, the lowest months. Those are among San Francisco's driest months, with about 15 mm of rain a month against 110 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Bathroom Moth Fly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
150th of 163
Of the 163 cities where we can rate Bathroom Moth Fly sightings, San Francisco ranks 150th at under 5%. The best odds are in Kuwait City (Kuwait, about 60%), Doha (Qatar, about 50%) and Prayagraj (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Bathroom Moth Fly is recorded against all the insects logged in San Francisco (174 verified sightings), 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.
