Fungus Gnat

Damp environments, typically found in potting soil of houseplants, greenhouses, and moist organic mulch.

Larvae feed on fungi, algae, and decaying plant matter in the soil; adults typically do not feed or consume nectar.

Weak flyers often seen crawling on soil or hovering near light sources. They have a short life cycle of about 3-4 weeks from egg to adult.

Generally harmless to humans but can be a nuisance indoors. Large larval populations may damage plant roots, while they benefit ecosystems by breaking down organic matter.
