Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

Black Arches Lymantria monacha

(Linnaeus, 1758)


Wingspan 30-50 mm.

This attractive black and white species often shows traces of bright pink on the body, especially the abdomen, which however is normally concealed when at rest.

The males, which can be attracted to light, are smaller than the females, but have very large, feathery antennae.

Distributed mainly throughout the southern half of Britain, chiefly in woodland habitats, the adults fly in July and August.

The larvae feed in the spring, usually on oak (Quercus), but sometimes on coniferous trees.
