About Calyptra thalictri Borkhausen, 1790
Calyptra thalictri is a moth species belonging to the family Erebidae. Its native range extends from Japan, Korea, China, and Malaysia, westward through the Ural Mountains to Southern Europe. The species has recently expanded its range into northern Europe: it was first observed in Finland in 2000, and recorded further west in Sweden in 2008. It is commonly called the vampire moth, though this common name is also used for other species in the genus Calyptra. The name refers to the moth's ability to drink blood from vertebrates, including humans, by piercing through skin. However, these moths are not considered to pose any threat to humans. This moth has a wingspan of 40 to 45 millimeters. Adults fly from May to September, with the exact timing varying by location. The larvae feed on plants in the genus Thalictrum.
