In Hampshire infrequently recorded and nowhere common, but has been recorded several times from Southsea; first recorded from the Isle of Wight in 2015. Wingspan 14-17 mm. Distinguished from A. francillana by the broader and less oblique median and postmedian fasciae of the forewing [Bradley]. Larva feeds within stems of Hemlock.
