The real shoulder runner ( Pterostichus oblongopunctatus ) is a beetle from the family of ground beetles (Carabidae).
features
The beetles reach a body length of 9 to 12 millimeters. Their body is black in color and has a greenish or bronze tinge. The upper wings ( elytra ) are longitudinally grooved and have four to seven, usually five, deep pore points in the third stripe. The similar four-pit grave beetle ( Pterostichus quadrifoveolatus ) usually only has three such points. The splints ( tibiae ) and tarsi are colored brown-red. The pronotum is shaped like a heart and has two wide, slit-like notches at its base.

Way of life
