Ophion variegatus

Length 15-22 mm. Identified the pale stripes on the thorax and by pale corners of the 'stigma' (the dark mark on the leading edge of the forewing). Many species of Ophion look similar therefore field identification is difficult. When viewed dorsally they have a long narrow reddish brown body but from a side view, the thin curved waist broadens out to a deep abdominal region. Late winter and spring-flying (before June) specimens in this complex all seems to be Ophion variegatus.
