Drain Fly Larva
Psychoda spp.
- Order & Family
- Diptera: Psychodidae
- Size
- 3mm to 10mm (approximately 1/8 to 3/8 inch) in length
Natural Habitat
Moist environments containing decomposing organic matter, such as drains, sewage treatment plants, septic tanks, and wet compost.
Diet & Feeding
They feed on the gelatinous film of organic sludge, bacteria, fungi, and algae that accumulates in drains and pipes.
Behavior Patterns
The larvae live within the 'slime' of drains where they consume organic debris. They are highly resilient to temperature changes and low oxygen environments. Once they mature, they pupate and emerge as moth-like flies.
Risks & Benefits
They do not bite or transmit diseases through stings, but they can be a nuisance and may potentially transport surface bacteria from sewage onto food surfaces. They benefit the ecosystem by breaking down organic matter in drains.
