The larvae feed on "Alnus glutinosa". The larvae feed on the catkins of birch ("Betula" spp) and alder ("Alnus glutinosa"). The larvae feed on "Betula" species and "Alnus glutinosa". Alder ("Alnus glutinosa") is a common host. The larvae feed on "Alnus glutinosa" and "Alnus incana". The alder ("Alnus glutinosa") carrs away from the rivers, however, were turned into grazing land. Glutinic acid, a substituted allene, was isolated from "Alnus glutinosa" (Betulaceae). Alder "Alnus glutinosa" and willow "Salix" species are part of the open water. At Mohos, vegetation consists of "Alnus glutinosa" (common alder), "Betula pendula" and "Salix".
