Fungus Gnat

Damp environments rich in organic matter, such as overwatered houseplants, greenhouses, and moist soil

Larvae primarily feed on fungi, algae, and decaying organic matter in soil; adults do not feed or may consume water and nectar

Poor fliers that often run across surfaces or fly in jerky, zigzag patterns; attracted to light and moist environments for egg-laying

Generally harmless to humans but can be a nuisance; larvae may damage plant roots in high populations, while adults help decompose organic material
