Blepharidopterus angulatus
Black Kneed Capsid
Family: Miridae

 A slender and parallel-sided blue-green species with black patches at the base of the rather bristly tibia ('knees'), parts of the antennae and at the posterior angles of the pronutum. The length of the 1st antennal segment is roughly equal to the width of the head. The antennae are usually very long in males. The yellow markings on the scutellum and forewings are variable.

A very common bug throughout Britain on many deciduous trees, including birch, alder, apple, lime, and ash. Partly predatory, feeding largely on red spider mites.
