Fungus Gnat

Damp, decaying organic matter; commonly found in potted plants, compost piles, and moist soil. Indoors, they are attracted to overwatered plants.

Larvae feed on fungi, decaying plant matter, and sometimes plant roots. Adults do not feed significantly and primarily focus on reproduction.

Adults are weak fliers and often seen walking on surfaces or flying erratically around plants. Larvae are found in the soil. They thrive in moist conditions and their presence often indicates overwatering of plants.

Risks: Larvae can damage plant roots, especially in seedlings and young plants, leading to wilting or stunted growth. They can also be a nuisance indoors. Benefits: Adults are pollinators to a limited extent, and larvae contribute to decomposition of organic matter in outdoor environments.
