Technical description and variation
The wingspan is 32–34 mm. The length of the forewings is 13–15 mm. Forewing greyish ochreous, sometimes uniformly washed with brownish; the lines and stigmata dark grey, the latter with pale annuli; submarginal line luteous preceded by a dark grey shade; hindwing dirty pale grey in male, darker in female, and darker in both sexes in the brown suffused forms: - the form sericea Speyer, from Holland and Germany, is described as having narrower silky grey forewings; -in [now full species levis Stgr.], from W. Turkestan and Asia Minor, the yellower ochreous tint is predominant and the dark markings are conspicuous but in some pale examples from Segovia, Spain- ab. ochrea ab. nov. [Warren] the dark markings tend to become effaced, the head, thorax, and forewings being pale yellow ochreous - amurensis Stgr. indicates small dark examples from Ussuri, Amurland. Similar to and confused with Hoplodrina octogenaria and Hoplodrina blanda. Certain identification requires dissection of the genitalia.See Townsend et al.
