Fungus gnat (likely)

Moist potting soil, decaying organic matter, greenhouses, and humid indoor areas. Adults may rest on fabrics, windows, or walls.

Larvae feed mainly on fungi, algae, and decaying plant material, sometimes damaging fine plant roots. Adults feed little, consuming moisture or occasionally nectar.

Weak fliers that often walk or make short flights; adults are attracted to light and moisture. Females lay eggs in damp soil, where larvae develop before pupating.

Generally harmless to people and pets and do not bite. Larvae can stress seedlings and houseplants, while adults and larvae contribute to decomposition and nutrient cycling.
