(Stephens, 1852)949 / 49.122

Morley’s Final Catalogue: Two specimens on yarrow on the cliffs at Felixstow in 1901 (Pyett); on the Breck at Mildenhall in mid-August 1934 and at Blakenham chalk-pits in July 1935 (Mly).

Recent Status:: A rare species with few Suffolk Records.

Life Style: Single brooded flying at dusk during July and August. The larvae feed on the seeds of Pastinaca Wild Parsnip or Heracleum Hogweed. It then bores into the stem where it hibernates. Often, but not exclusively, found coastal.

Identification: The moth has a pale yellow/ochre forewing with brown oblique bands similar to A. francillana and A. beatricella. The bands are narrow but not as acute at the apex as francillana and the proximal band does not reach the costa. More Info
