Drain Fly (Larva)

Moist areas containing organic slime, such as bathroom drains, sewers, and septic tanks.

Feeds on decaying organic matter, algae, and microscopic organisms found in gelatinous drain films.

The larvae live submerged in drain slime, breathing through a small tube; they pupate near the surface before emerging as fuzzy, moth-like adults.

While they do not bite or spread disease, large numbers can be a nuisance and indicate a clog or sanitation issue; they are beneficial by breaking down organic waste.
