About Pachycnemia hippocastanaria (Hübner, 1799)
Pachycnemia hippocastanaria, commonly known as the horse chestnut moth, is a moth species that belongs to the family Geometridae. This species can be found across most of Europe. It has a wingspan that ranges between 28 and 32 millimeters. Adult moths are active from April through May. In many cases, a partial second generation of adults emerges in August; this generation typically produces fewer moths, and the individual moths are smaller than those from the first generation.
