    Length 8-11.5 mm. A distinctive species, although similar to the Hawthorn Shieldbug (see below).

    Similar Species

    Confusion with the larger and more elongate Hawthorn Shieldbug (A. haemorrhoidale) is possible. The lateral extensions of the pronotum are smaller in E. interstinctus, and are not marked with red, while the scutellum of A. haemorrhoidale is green and the abdomen frequently red-tipped.
