Ophion obscuratus (ichneumon wasp) Garden

Description
Length: 15 to 22 mm. Ophion obscuratus is identified by pale corners of the ‘stigma’ (the dark mark on the leading edge of the forewing) and the distinctive pale marks on the top of the thorax. Many species of Ophion genera 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
When to see it
April – October
Life History
Females lay their eggs in the caterpillars of various noctuid moths. Because of this, they have no need of the long (sting like) ovipositors which many of the other ichneumons need to reach deep seated wood boring larvae.
UK Status
