Araschnia levana

The same species as in yesterday's post. This image displaying the full color pattern of the upper side of the wings (spring brood.)

Araschnia levana (NL: Landkaartje / EN: Map / DE: Landkärtchen) is a small butterfly of the Nymphalidae family (forewing about 17-21 mm). When you look at the underside of the wings it is not hard to imagine how this butterfly got it's name (see yesterday's post). The species is common throughout the lowlands of central and eastern Europe, and is expanding its range in western Europe. The eggs are laid in long strings, one on top of the other, on the underside of stinging nettles, the larval foodplant. It is thought that these strings of eggs mimic the flowers of the nettles, thereby evading predators. The larvae feed gregariously and hibernate as pupae. The Map is unusual in that its two annual broods look very different. The summer brood are blackish with white markings, looking like a miniature version of the White Admiral and lacking most of the orange of the spring brood (this image). This seasonal dimorphism is thought to be related to the diapause (= the delay in development in response to regularly and recurring periods of adverse environmental conditions) which the hibernating pupae of the spring brood undergo.
