Drain Fly Larva (or Moth Fly Larva)

Moist environments with decaying organic matter, such as drains, sewers, septic tanks, compost piles, and wet soil.

Feeds on organic matter, including decaying plant and animal material, fungi, and biofilms that form in drains and pipes.

Larvae develop in cracks and crevices, feeding on organic matter. They are often found in bathrooms, kitchens, and basements. They are generally slow-moving.

Generally considered a nuisance pest, but not known to transmit diseases to humans. Large infestations can indicate a sanitation issue. They play a role in breaking down organic matter.
