Fungus Gnat (likely)

Natural Habitat

Damp environments, often potted plants, greenhouses, and areas with decaying organic matter. Larvae live in soil.

Diet & Feeding

Adult fungus gnats typically do not feed or feed on liquids. Larvae feed on fungi, decaying organic matter, and sometimes plant roots, especially fine root hairs.

Behavior Patterns

Adults are weak fliers and are often found near the soil surface of potted plants or flying erratically. They are attracted to light and moisture. Larvae live within the soil or growing medium and are responsible for any plant damage.

Risks & Benefits

Risks: Can be a nuisance indoors in large numbers. Larvae can damage plant roots, especially seedlings and young plants, leading to wilting, stunted growth, or even plant death. They can also spread plant pathogens. Benefits: Contribute to decomposition of organic matter in natural environments.
