Similar species: See Angle-barred Pug for distribution. John Langmaid (in corres., 2013) advises that in the forthcoming check-list that Ash Pug will be treated as Angle-barred Pug E. innotata (Hufnagel) but with a note that 'opinions differ'.

Sutton & Beaumont, 1989: The distribution of this pug has changed very little over the past twenty years. There is still one coastal colony, where it was originally known as E. innotata (Hufnagel) (see comment in YNU, 1970), feeding on sea buckthorn, and a few inland ash-feeding colonies.

2012 (CHF): The true ash-feeding form (Ash Pug) is commonest in the western Dales though it can turn up elsewhere. Sometimes misidentified - take care if recording this species away from the coast or the Dales.
