Nezara viridula
Southern Green Shieldbug
Family: Pentatomidae

A recent arrival in the UK, this large shieldbug 
differs from the much commoner Common Green Shieldbug Palomena prasina by the 3-5 white spots along the front edge of the scutellum and by the two dark marks at its corners. This species is uniformly green, lacking dark puncture marks, and the wing membrane is pale (but see freshly emerged P. prasina). In some individuals, the head and front margin of the pronotum is cream-coloured.

Native to Africa, but frequently imported to the UK in food produce,
it is widespread in southern Europe and has been recorded annually from sites in southern England since 2003 on various foodplants including tomato, beans, golden-rod, Lavatera, Viburnum and hemp agrimony. Manyrecords are from allotments where bugs are associated with cultivated beans.

Adult: All year
Length 11-15 mm
