Drain fly or moth fly

Found indoors near damp areas, bathrooms, kitchens, and plumbing drains.

Larvae feed on decaying organic matter, sludge, and bacteria in drain biofilms; adults consume nectar or polluted water.

Weak fliers that rest on walls and mirrors, often erratic when disturbed. Females lay eggs in gelatinous films inside pipes.

Generally harmless to humans and do not bite, though large infestations can indicate plumbing issues or trigger minor allergies.
