Notes:
Extinct in the British Isles, formerly in sand-dunes and shingle beaches in parts of southern England. Unlikely to be recorded in Hampshire or on the Isle of Wight. Wingspan 13-17 mm. Similar to A. williana but distinguished by its larger size and the yellower general appearance of the forewing, and in the male the presence of mottling on the hindwing [Bradley]. Larva feeds on flowers of Sea Holly.
