Drain Fly Larva

Moist, organic-rich environments such as drains, septic tanks, sewers, and damp soil

Decaying organic matter, algae, bacteria, and fungi (biofilm)

Lve in sludge and gelatinous films; they breathe through a tube-like siphon and are resilient to temperature changes and low oxygen

Harmless to humans but can be a nuisance; benefit the ecosystem by breaking down organic waste in plumbing systems
