Family common name: common sawflies
Genus: Brachythops Curtis, 1839
The Tenthredinidae are the most species-rich family and are found throughout the world, in all continents but Antarctica. They are known as the “common sawflies.” They can generally be recognized by a cylindrical body and long, segmented antennae. Otherwise, they come in a variety of colors, sizes, and forms (Goulet 1992).
Sawflies in the Selandriinae subfamily are relatively small and slender. The range of Selandriinae is worldwide; it occurs on all continents except Antarctica (Goulet 1992). It is the most common and diverse group of tenthredinids in tropical regions, particularly in Central America, South America, and Southeast Asia (Smith 1969e). Selandriinae contains the only known sawflies that feed on non-vascular plants, specifically ferns (Smith et al. 2013). The subfamily can be distinguished from other subfamilies by wing venation (Goulet 1992).
In North America, Brachythops feeds on Carex spp. (sedge) (Smith 1969e).
North America: Brachythops has a northern distribution and is found in Alaska, Yukon Territory, and Northwest Territories, and south through Canada into Colorado, Wisconsin, and New York in the United States (Smith 1969e).
