Indoor Soil Gnats

Bradysia is a genus of fungus gnat in the family Sciaridae. They are commonly known as darkwinged fungus gnats. They are considered a major pest in greenhouse agriculture because they thrive in the moist conditions common inside greenhouses and feed on the plants being grown within. Bradysia is a large genus containing over 500 living species, with at least 65 species found in North America and 172 in Europe.

Bradysia species are a major pollinator of plants such as Aspidistra elatior.
