Pallas’ fritillary is mainly found in Finland as a wanderer, and the population can survive in southernmost parts of the country after a year or two of wandering (a so-called temporary stay). The rare species can be differentiated from other larger Heliconians by the way that its hind wings are divided in two by colour. Additionally, there is quite a small white blotch close to the apex of the female’s forewing, which sets it apart from other Heliconians.
