The head, mesonotum and some of the abdomen is brownish to reddish-yellow. In the female, the scutellum lacks a black band across the posterior margin and the abdomen is at most marked with black along the midline of the basal three tergites. The mesonotum is dulled by fine surface sculpture. The antennae is entirely black except for the underside of the apical segments. Male undescribed.

Euura fahraei larvae feed on aspen. Probably more widespread than recorded in aspen thickets.
