About Saucrobotys futilalis Lederer, 1863
Saucrobotys futilalis, commonly known as the dogbane saucrobotys moth, is a species of moth belonging to the family Crambidae. It was first described by Julius Lederer in 1863. This moth is native to North America, where it has been recorded across a range stretching from the northeastern part of the continent west to British Columbia, and south to Texas and California. The forewings of adult individuals measure 14 to 16 mm in length. Adult moths are active in flight from May through July each year. The larvae feed on plants in the Apocynum genus, which includes Apocynum cannabinum, and on plants in the Asclepias genus, which includes Asclepias tuberosa. The larvae build silken nests on their host plants. To defend themselves against predators, the caterpillars regurgitate the contents of their digestive tracts.
