Ecology
Description and characteristics
Vanessa atalanta is a lepidopteran species in the family Nymphalidae. It is distinguished by its dark brown to black wings, which bear a bright red transverse band on the forewings and a red band on the hindwings, along with subapical white spots. It is a medium- to large-sized butterfly, with a wingspan that can reach 64 mm. In northern Europe, it is one of the last butterfly species to be seen before the arrival of winter, visiting ivy flowers on sunny days. Overwintering individuals tend to show darker coloration than the spring generation. This species is known for the territorial behavior of males, which defend specific areas to court females, and for its ability to migrate long distances, using air currents to save energy during seasonal movements.
