Toadflax Brocade Moth Calophasia lunula

The Toadflax Brocade moth colonised the UK in the 1950s and, as a breeding resident, inhabited mainly shingle and gravel areas near coasts in south and southeast England where there is access to the toadflax plant. Currently it seems to be moving further north. Brown-grey with strong markings, wingspan is 26-32mm. On the wing between May and August, it is also seen as a migrant in July and August, sometimes in gardens.

The Toadflax Brocade caterpillar has yellow and black markings and grey sides. It eats toadflax plants (both the Common yellow, where it is camouflaged and the purple, where it is more visible) between June and September before spending winter as a pupa.
