Potato capsid

Closterotomus norvegicus (also known as the potato capsid)
This plant bug has a long oval, green body with long antennae and hind legs. Males develop orange coloration as they mature.The Common Capsid is a very similar green bug but, the key to positive identification of the Potato Capsid lies in the two brown dots on the pronotum region just behind the head.however the two spots on the pronotum can be frequently absent, similarly the dark markings at the top of the scutellum.Specimens from northern Britain may have brownish-black markings.
