(Gmelin, 1790)[1]

Closterotomus norvegicus (also known as the potato capsid) is a species of bugs belonging to the family Miridae, subfamily Mirinae.[2] It can be found feeding on nettle, clover,[3] and cannabis,[4] as well as Compositae, potatoes, carrots and chrysanthemums.[5] They prefer to feed on the flowers, buds and unripe fruit.[6] The species occurs in Great Britain and continental Europe. In 1997 it was moved from the Calocoris genus to its current name.[7]

Description[edit]

The species is green coloured as a nymph, but when they get to adulthood the colour changes to reddish brown. It does however, vary by territory; for example, specimens from northern Britain are brownish black. The prothorax has two spots, while its scutellum has dark marks.[3]
