[3] The dark green scutellum band is trapezoidal in shape, and extends from the dorsal pronotum to the forewing hemelytral membrane which accounts for the final third of the main body length.
The front wings lie flat when the insect is not flying, with the sclerotized pronotum and corium regions coloured dark red.
The rostrum is a modified proboscis formed by the interlocking of mandibular and maxillary stylet into a double-tubed elongation covered by the labium.
[5] The hawthorn shield bug is found across Europe, from Portugal to Russia, and is common in the southern part of Great Britain.
[6] In Britain and North Western Europe the species is generally active between the months of April and October, although specimens can reappear from hibernation during periods of unseasonable warm weather in the winter.
