Fungus Gnat (likely)

Natural Habitat

Damp, organic-rich environments, often associated with potting soil of houseplants, compost, decaying leaves, or moist areas indoors.

Diet & Feeding

Larvae feed on fungi, decaying organic matter, and sometimes plant roots (especially tender ones). Adults do not feed significantly or feed on liquids like nectar.

Behavior Patterns

Adult fungus gnats are weak flyers and are often seen hovering around plants or windows. They are attracted to light. Females lay eggs in moist soil. Larvae hatch and develop in the soil. The life cycle from egg to adult can be as short as 3-4 weeks under ideal conditions, leading to rapid population growth.

Risks & Benefits

Risks: Larvae can damage plant roots, especially seedlings and young plants, leading to wilting, stunted growth, and yellowing leaves. They are generally considered a nuisance pest indoors. They do not bite humans or transmit diseases. Benefits: In natural ecosystems outdoors, they help in decomposition of organic matter. Indoors, they are generally not beneficial and often indicate overwatering of plants.
