Sciaridae, commonly known as dark-winged fungus gnats, are small flies belonging to the family of Diptera. They are typically found in damp environments, where their larvae feed on decaying organic matter, fungi, and plant roots. These gnats are often seen around houseplants and in greenhouses, as they thrive in moist soil. The adult Sciaridae are characterized by their slender bodies and long legs, with dark wings that give them their name. While they are generally harmless to humans, their larvae can damage young plants, making them a concern for gardeners and farmers. Effective management includes reducing excess moisture and using insect traps.
