The Admiral arrives every year to Denmark in June and July. It is probably overwintering butterflies from southern Europe.

Vanessa atalanta, the red admiral

The red admiral is found in temperate regions of North Africa, North and Central America, Europe, Asia, and island regions of Hawaii, and the Caribbean.

In northern Europe, it is one of the last butterflies to be seen before winter sets in, often feeding on the flowers of ivy on sunny days. The red admiral is also known to hibernate, re-emerging individuals showing prominently darker colors than the first brood. The butterfly also flies on sunny winter days, especially in southern Europe.

In North America, the red admiral generally has two broods from March through October. Most of North America must be recolonized each spring by southern migrants, but the species over winters in south Texas.
