Drain Fly (also known as Phorid Fly/Scuttle Fly)

Damp environments with decaying organic matter, such as drains, sewage pipes, trash cans, and rotting vegetation.

Larvae feed on decomposing organic material, sludge, and fungi; adults feed on juices from decaying matter and nectar.

Characterized by their jerky, running movement (scuttling) instead of flying immediately when disturbed. They exhibit a fast life cycle, developing from egg to adult in roughly 14-25 days.

They are considered a nuisance pest and a sanitation risk, as they can mechanically transport pathogens from waste to food surfaces. They do not sting or bite humans.
