Berberis Sawfly ... ?

Saw this in a friend's garden a couple of days ago. Her 20 year old berberis bushes were ravaged last year by larvae that completely stripped the leaves leaving a very sad looking skeleton and I am wondering if this is an adult Berberis Sawfly. Going to pay a return visit tomorrow, if dry, to look for the offending larvae and see what can be done to relieve the problem.
