Small fly (likely fungus gnat)

Moist soil, decaying plant material, fungi, and indoor potted plants. Adults may appear near windows or lights.

Larvae commonly feed on fungi, decaying organic matter, and occasionally plant roots. Adults consume little, often taking moisture or nectar.

Adults are weak fliers and may gather around damp soil and lights. Larvae develop in moist organic substrates, with several generations possible indoors.

Usually harmless to people and pets; heavy larval infestations can damage seedlings and houseplants. They help decompose organic matter and serve as prey for predators.
