Distribution:

Following Karsholt & Nieukerken (2010), the species is known from the Iberian peninsula throughout central and southern Europe to the east of European Russia, but is missing in most parts of north-western and northern Europe, in some southern European countries and also in Asia (Dubatolov 2009, anonymous 2009a). Vertically, A. violella has been recorded from the lowlands up to more than 1300 m a.s.l. (Kurz & Kurz 2010).
