Featured Subspecies: ?
Weight: ?  /  Length: 8-9mm  /  Wingspan: ?
NO UK STATUS / IUCN Red List: Not Yet Evaluated 

A widespread small shieldbug that doesn't match the typical "look" of the family that most people expect - there is still a roughly shield like shape but it lacks the very broad "shoulders" of the more familiar species.  The striping is also distinctive - with the overall impression being something along the lines of a faded sunflower seed with a greenish tinge.  Widely found in Southern Britain, it has one new generation per year.

Order: Hemiptera
