Ancylis achatana
Triangle-marked Roller

([Denis & Schiffermüller], 1775)1115 / 49.215

Morley’s Final Catalogue: Pretty surely frequent, but rarely observed. First taken at Hemley in 1903 by Waller (EMM. 1904, 80); close beside Covehithe Broad in July 1912; and only once at Monks Soham light, on 24 July 1921 (Mly).

Recent Status: A common species in Suffolk.

Life Style: A single brooded summer flying species. It flies at night and comes to light. The larvae feed from spun rolled leaf or leaf clusters on Crataegus, Prunus spinosa or Cotoneaster. It pupates in the feeding location.

Identification: This species is easily recognised by the prominent pre-tornal triangular patch and the band that marks off the wing apex. The colours vary considerably. The extent of the markings varies a little.
