Fungus Gnat

Natural Habitat

Damp, moist environments, especially where there's decaying organic matter. Commonly found around potted plants, greenhouses, and unkempt organic waste.

Diet & Feeding

Larvae feed on fungi, decaying plant matter, and sometimes plant roots. Adults do not feed much, but may consume liquids.

Behavior Patterns

Adults are weak fliers and are attracted to light. Larvae live in the soil or substrate, often causing damage to plant roots if in large numbers. Short life cycle, leading to rapid reproduction in favorable conditions.

Risks & Benefits

Risks: Larvae can damage plant roots, especially seedlings, leading to stunted growth or death of plants. They are mostly a nuisance pest indoors. Benefits: Adults are pollinators for some plants. Larvae can help with decomposition of organic matter in natural settings.
