Drain Fly

Scientific Name: Psychodidae spp
Drain flies are also called sink flies, filter flies, or sewer gnats.
From the diverse Diptera (True Flies) Family Psychodidae hence we are not using their specific scientific names as this requires taxonomic works. Laboratory research to be exact.
They are small with short, hairy bodies and wings giving them a “furry” moth-like appearance, hence one of their common names, moth flies.
Drain flies inhabit plumbing drains and sewage systems also the wall and floor junction especially if the grouting is worn-out and moisture is present.
They are a harmless but persistent annoyance.
