Map

Appearance

The Map is unusual in that its two annual broods look very different. The summer brood are black with white markings, looking like a miniature version of the White Admiral and lacking most of the orange of the pictured spring brood.

Distribution

In the UK this species is a very rare vagrant, but there have also been several unsuccessful – and now illegal – attempts at introducing this species over the past 100 years or so: in the Wye Valley in 1912, the Wyre Forest in the 1920s, South Devon 1942, Worcester 1960s, Cheshire 1970s, South Midlands 1990s. All these introductions failed and eggs or larvae have never been recorded in the wild in the UK.

Reproduction

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.
