Drain Fly Larva

Moist environments rich in organic matter, such as drains, sewer pipes, septic tanks, and wet soil.

Scavengers that feed on the gelatinous film of bacteria, fungi, and decomposing organic material found in drains.

The larvae live submerged in slime or film; they breathe through a small tube at their tail. They undergo multiple molts before pupating and emerging as adult flies.

Generally harmless to humans, though they can be minor household nuisances. In the ecosystem, they are beneficial as decomposers that help break down organic waste.
