Small fly; likely a fungus gnat

Often found around damp houseplant soil, greenhouses, and other moist, organic-rich environments.

Larvae feed on fungi, decaying organic matter, and occasionally tender plant roots; adults mainly take liquids or do not feed.

Adults are weak fliers and commonly hover near potted plants. Larvae develop in moist soil, with generations recurring indoors when conditions remain damp.

Generally harmless to people and pets; large numbers of larvae can damage young plants or roots. They also help break down organic matter.
