[Ligne directrice - Note] Note du photographe
The Blackleg Tortoiseshell or Large Tortoiseshell (Nymphalis polychloros) is a butterfly of the family Nymphalidae. Although it looks very like the Small Tortoiseshell (Nymphalis urticae), it is more closely related to the Camberwell Beauty. It is now an extreme rarity in Britain, although it used to be widespread throughout England and Wales. Most of the specimens seen in Britain are thought to be captive-bred releases.
The adult insect (imago) over-winters in dry dark places, such as hollow trees or out buildings. In early March the butterflies emerge and mate. The females lay their pale green eggs (ova) in a continuous band around the upper twigs of Elm (Ulmus spp.) or Sallow (Salix caprea) trees. The caterpillars (larvae) are gregarious, and systematically strip the topmost twigs of the tree bare. They seem to have little defence against predation by birds. It is possible that their decline and extinction in the British Isles (late 1970s) was due to the loss of predatory birds, which previously had preyed upon smaller birds if they strayed to the tops of these trees.
