Scientific name: Cilix glaucata
Two generations from late April to early June and July to early September. Widespread and well distributed across England, Wales, Ireland and the south of Scotland.
This unmistakeable moth uses visual mimicry to avoid being eaten. When at rest the wings are held steeply over the body and combined with a white, brown and grey wing pattern it closely resembles a bird dropping.
A nocturnal species, they can sometimes be found at rest on vegetation during the day. They are regularly attracted to light. The caterpillar can be seen from mid-June to mid-July and late August to September. They overwinter as pupae in cocoons attached to leaves, debris or bark.
