Dark-winged Fungus Gnat

Natural Habitat

Commonly found in damp environments, particularly in household potted plants, greenhouses, and areas with high humidity or decaying organic matter.

Diet & Feeding

Adults generally don't eat much but may drink water or nectar. Larvae feed on algae, fungus, and decaying plant roots in soil.

Behavior Patterns

Adults are weak fliers often seen running across soil surfaces or resting on leaves. They are attracted to damp organic material where they lay eggs.

Risks & Benefits

Generally harmless to humans (they do not bite), but can be annoying pests in homes. Heavy larval infestations can damage plant roots, stunting growth, particularly in young seedlings.
