The green shield bug (Palomena prasina) is a species of shield bug in the family Pentatomidae. It is commonly found throughout Europe, including Great Britain and Ireland, in a large variety of habitats, including gardens. The species displays different colouration during each nymphal stage, light brown, black or green-black, and in the final stage, the imago, is bright green with short wings. The imago stage is usually reached in September, with hibernation occurring in November. This green shield bug was photographed on Cumnor Hill in Oxfordshire, England.Photograph credit: Charles J.
