This moth looked to be no more than a speck among the many bird droppings on the sheet. I would have paid no more attention to it if it weren’t for the reddish tint near the tip and the unusual shape of the midbody fascia which is joined up with the first pair of costal streaks via a diffused, angled band. This species used to be more concentrated in the South but is possibly expanding northwards. It feeds on hawthorn and blackthorn.
The name ancylis, derived from ‘agkulis’ or angle, describes its hooked wings. Achates means a banded gemstone such as agate, which the markings resemble.
The moth has appeared on our blog before as part of a two-trap venture at Barley Studio and Keith Barley’s garden in Warthill, but this is the first time it has been found in our own gardens.
