Author 'Boucher Marc dit de Meilh' (Id 118013 ) : Common in Europe, the golden rose chafer (Cetonia aurata) is a beetle of the family Cetoniidae. This species is often a great variation in color from an emerald green metallic, olive and sometimes more or less intense ... I also noticed the color gold, orange, purple, mauve, dull green pulling black. These color differences visible to the naked eye, changing depending on the exposure of the insect to sunlight ... This Cetonia busy on the white petal ate pollen from a pretty wild rose. On the heights of 38,300 Rosière, away from the woods into a clearing wild and sunny, in the wasteland. Otherwise, I have nothing further to report. Marc Boucher said Meillan.
