Hesperumia
sulphur moth
Hesperumia is a genus of geometrid moths established by Packard in 1873. The genus contains four recognized species distributed across western North America, with adults typically active during summer months. Larval stages are poorly documented, but the genus is associated with various host plants including buckwheat and other herbaceous vegetation. Adults of at least one species, H. sulphuraria, are attracted to light sources.
