Local in dry pastures, downland and waste ground throughout much of the British Isles, predominantly coastal in the north of its range. In Hampshire largely absent from the New Forest and uncommon in the north, but fairly widely distributed in the south-east and along the chalk. On the Isle of Wight, there are no recent records, but it has occurred in the past. Wingspan 13-18 mm. Differs from
A. dilucidana in having the median fascia of the forewing complete; compared with
A. beatricella the median and postmedian fasciae are narrower and more oblique, the costal end of the median fascia extending beyond the dorsal end of the postmedian [Bradley]. Larva feeds on seeds of Wild Carrot, living between flower heads spun together with silk.
