Fungus gnats – Larva
Fungus gnat larvae (Bradysia spp.) are white and legless, about 1/4 inch long when mature, and have a shiny black head. Larvae feed on fungi and decaying matter, often injuring bulbs, seedlings and plants with succulent stems and roots. Fungus gnats can be monitored using potato slices. Larvae present in infested plants or media can lead to prolonged emergence of adult flies.
