face is divided by a vertical black bar and the malar (distance between
bottom of eye and jaw) space is long. Antennae are yellow at the base.
The thorax has black hairs at the side and two yellow spots at the rear.
The abdomen is often red at the front. The nest is like that of the Tree
Wasp but with looser covering. Very widespread but more common in the
North. The D.saxonica (not pictured) is very similar but
the face bar is often irregular and the thorax has pale hairs at the side.
The abdomen is never red.
