Green Shieldbug (Palomena prasina).. in wintercolor



The green shield bug (Palomena prasina) is a shield bug of the family Pentatomidae. It may also be referred to as a green stink bug, particularly outside of Britain, although the name green stink bug more appropriately belongs to the larger North American stink bug, Acrosternum hilare. The adult green shield bug ranges in the colour of their backs from bright green to bronze, without any substantial markings. Green shield bugs are a very common shield bug throughout Europe, including the British Isles, and are found in a large variety of habitats, including gardens. They have been found as far north as 63 N latitude.




In Europe, the bright green shield bugs appear in May, having hibernated as imagos during the winter. They fatten for a month and then mate in June. Copulation is back-to-back in typical Heteropteran mating position, as they are not flexible enough for both to face forward. The female lays her eggs in hexagonal batches of 25 to 30, and a single female will lay three to four batches. The imago's colouration changes over the summer from green to a greenish brown almost a bronze, before death. After the eggs hatch, the green shield bug enter their larval stage (which is really their first nymphal stage) where, in general, they remain together in sibling communities. This is made possible by the excretion of an aggregation pheromone. In case of danger, another pheromone is released which causes dispersal. The larval stage is followed by four more nymphal stages with a moult between each one. The green shield bug 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. Usually the imago stage is reached in September, with hibernation occurring in November.

Hello Juliette

Great macro of green shield bug in a diagonal align. I like this way of POV. Nice lighting, nice BG, excellent sharpness and details. The species name "prasina" means green in greek (πρασινα). Thanks for sharing.

Very nice macro: sharp, excellent light, good composition in the diagonal. Maybe a bit too tight a frame with the antenna very close to the top left corner.
