About Deileptenia ribeata (Clerck, 1759)
Deileptenia ribeata, commonly known as the satin beauty, is a moth species belonging to the family Geometridae. It was first described by Carl Alexander Clerck in 1759. This species is distributed from Ireland, extending eastward through central Europe to Russia and Japan. The wingspan of adult Deileptenia ribeata measures 30–40 mm. The ground colour of its forewings is typically mid to dark brown, and the forewings have a slightly mottled appearance. Deileptenia ribeata is very similar in appearance to the mottled beauty (Alcis repandata), as well as Peribatodes rhomboidaria, Peribatodes secundaria, and Peribatodes ilicaria. For further identification details, see the work of Townsend et al. Adults of this species are active on the wing from June to August, and there is one generation per year. The larvae of Deileptenia ribeata feed on a wide variety of trees, including multiple coniferous species. Recorded host plants include Taxus baccata, Abies alba, Carpinus betulus, Betula, Quercus, Prunus spinosa, Vaccinium uliginosum, Lonicera xylosteum, and Picea.
