This fly is about the size of a large bluebottle fly. It has yellowy orange sides to the abdomen and a zig-zag central band. Like all Tachinids it has numerous bristly hairs on the abdomen.
Peak time is June to August.
The maggot stage of the fly develops inside the Dark Arches moth, eating it from within, and then emerging to pupate.
This species is distributed in the southern half of Britain, mainly in southern England and South Wales.
Status in Leicestershire and Rutland not known.
