In the medium live over 200 species of bacteria, algae, worms, protozoa, and insects including larvae of the drain fly; together these organisms form a biofilm which processes the fluid passing through the filter system and removes pollutants. First, figure out where drain flies are coming from. The larvae resemble mosquito larvae, in that they are slender, white to creamy brown with a distinct head, well- developed mouthparts, and an apparent siphon (Figure 2). The larvae are slender, whitish, cream or pale brown, with a head with strong jaws, 11 body segments, and siphons on the hindermost two segments. In the medium live over 200 species of bacteria, algae, worms, protozoa, and insects including larvae of the drain fly; together these organisms form a biofilm which processes the fluid passing through the filter system and removes pollutants. The adult insects seldom move far from where they were hatched. The adults normally remain in proximity to the larval habitat, where they mate and oviposit shortly thereafter. The larvae can be found feeding on the film of wet organic material that can accumulate in drains. [7], Originating in North America, this insect has spread around the world. The larval stage lasts for about 15 days at 70 °F, and it is in the larval stage that the insect will usually overwinter, in diapause.
