Four-spotted Moth Tyta luctuosa
This scarce and vulnerable species was once widely distributed in the south, but is now restricted to a few small populations in Dorset, the Brecks and elsewhere. The larvae feed on field bindweed (Convolvulus arvensis), and prefer the buds of flowers. Image: Mervyn Crawford (Flickr).
