Number 7173. These look like dark-winged fungus gnats (Diptera: Sciaridae). They breed primarily in very wet/water-logged soil having a high organic content. The most effective control is to allow the soil in potted plants to dry out as much as practical between waterings. The flies are harmless nuisance pests, but their larvae sometimes can cause damage to very tender plant parts. Fungus Gnats Control Suggestions
