Drain Fly Larva (likely identification based on shape and context)

Moist, organic-rich environments such as drains, sewage filters, compost piles, and bathroom grout. They thrive in the slimy film that builds up in plumbing.

Feeds on decaying organic matter, sludge, algae, bacteria, and fungi found in drains and moist areas.

Larvae are semi-aquatic but breathe atmospheric oxygen. They are often found wiggling near drains or on shower walls. They go through a pupal stage before emerging as adult 'moth flies'.

Generally harmless to humans (they do not bite or sting). However, they can be a nuisance pest in homes. In large numbers, they can indicate plumbing issues or unhygienic conditions. Excessive populations can potentially mechanically transport bacteria from sludge to surfaces.
