Drain Fly Larva

Found in moist, organic-rich environments such as drains, sewage pipes, septic tanks, and wet compost.

They feed on sludge, slime, and gelatinous films of algae, bacteria, and fungi that accumulate in drains.

Larvae are aquatic or semi-aquatic. They breathe through a small tube at their rear end and can survive in low-oxygen environments by staying at the surface of the slime layer.

Generally harmless to humans. While they do not bite or spread disease like mosquitoes, large numbers can indicate a hygiene issue or a plumbing clog. They benefit the ecosystem by breaking down organic matter.
