Scientific name: Charissa obscurata
July to August. Britain and Ireland. Medium-sized, colours range from white to grey to black.
Often found near sea campion, thrift and rock-rose. Found on rocky coastlines, beaches, heathland, moorland and downland. The variable colour of this moth appears to match the ground colour of its habitat, ranging from almost white on chalk and limestone to brown/black on heaths and bogs. Markings are less variable, with hollow circles and two jagged lines crossing both sets of wings, but these are less easy to see on the darker forms.
The adults rest by day on bare ground, in rocky crevices and behind overhanging vegetation, flying from dusk and after dark. The larvae can be seen from September to the following late May, overwintering near the base of the foodplant. They pupate on the ground among plant debris.
