Cetonia aurata
''Cetonia aurata'', called the rose chafer or the green rose chafer, is a beetle, 20 mm (¾ in) long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.
''Cetonia aurata'' should not be confused with the North American rose chafer, ''Macrodactylus subspinosus'', or with the rarely seen noble chafer, ''Gnorimus nobilis'', which is is very similar to the rose chafer. One way to identify ''Cetonia aurata'' is to look at its scutellum; on the noble chafer the scutellum is an equilateral triangle, but on the rose chafer it is an isosceles triangle.
==Overview==
Rose chafers are capable of fast flight; they fly with their wing cases down. They feed on pollen, nectar, and flowers, especially roses. They can be found among roses on warm sunny days from May until June or July, and occasionally as late as September. Rose chafers are found in southern and central Europe and in the southern part of the United Kingdom, where they sometimes seem to be very localized. They are a beneficial saprophagous species (detritivores).
