Hello! On May 17th, 2020, I observed this fly resting on a stone next to the river Rhein close to Worms, Rheinland-Pfalz, Germany. It flew away very quickly, so I couldn't get another or better picture. In the immediate surroundings, there are bushes, a line of trees and fields. Could it be an Eumerus? Thank you in advance! Ina
