Small fly or gnat (image too blurred for species-level identification)

Fungus gnats commonly occur around damp potting soil, decaying plant material, greenhouses, and moist indoor areas.

Adults often consume little or feed on nectar; larvae commonly eat fungi and decaying organic matter, and some damage plant roots.

Adults are weak fliers attracted to moisture and light, often hovering near plants. Larvae develop in moist soil or organic debris, completing multiple generations per year indoors.

Generally harmless to people and pets and do not bite. They help decompose organic matter, though larvae can stress seedlings and houseplants when abundant.
