Fungus Gnat

Damp soil, decaying organic matter, and indoor potted plants

Larvae feed on fungi, algae, and plant roots; adults do not feed or consume liquids only

Attracted to light; slow, weak flyers often seen crawling on surfaces or soil; short life cycle of about 3-4 weeks

Harmless to humans; larvae can damage plant roots in high populations; benefit as decomposers of organic matter
