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.

Twin-spotted Quaker Anorthoa munda

([Denis & Schiffermüller], 1775)

Wingspan 38-44 mm.

A variable species, with forewings ranging from pale buff to reddish-brown.

The blackish twin spots are usually obvious, but in some forms, including ab. immaculata, these are reduced to barely discernible rufous marks, or obsolete.

It is widely distributed in woodland habitats in England and Wales, but local in Ireland and Scotland. Flying in March and April, like several related species, it can be found feeding on sallow blossom at night.

The caterpillars feed in early summer on various trees, including oak (Quercus), aspen (Populus tremulata) and sallow (Salix).
