Fungus Gnat (likely)

Scientific Name: Sciaridae or Mycetophilidae (Family)

Order & Family: Diptera (Order), Sciaridae or Mycetophilidae (Family)

Size: 2-8 mm (adults)

Fungus Gnat (likely)

Natural Habitat

Damp, moist environments, often found near houseplants, decaying organic matter, or areas with high humidity.

Diet & Feeding

Larvae feed on fungi, decaying plant matter, and sometimes plant roots. Adult fungus gnats do not feed significantly and are mainly concerned with reproduction.

Behavior Patterns

Adults are weak fliers and are attracted to light. Larvae live in the soil or decaying matter. They have a short life cycle, and infestations can quickly grow if conditions are favorable (e.g., overwatered plants).

Risks & Benefits

Risks: Larvae can damage the roots of seedlings and young plants, leading to wilting and stunted growth. They are generally considered a nuisance pest in homes and greenhouses. Benefits: In natural environments, they contribute to decomposition processes by consuming fungi and decaying organic matter.
