Stenochironomus is a monophyletic genus found over much of the world. Look for these midges near running water.
Borkent (1984) summarized the larval traits this way: "A dorsoventrally compressed head capsule, expanded thoracic segments and a long, flaccid abdomen."
Adults typically are greenish with dark markings on the wings and abdomen. The very long front legs are often held in a backswept way.Photo location: Kumbrabow State Forest, Randolph County, West Virginia.
