摘　　要：通过鸟类视觉模型,比较白星花金龟Protaetia brevitarsis Lewis成虫古铜色和青铜色体色组成及差异,分析两种体色在绿叶和树皮自然背景下的识别度.结果显示古铜色和青铜色体色白星花金龟成虫在蓝山雀眼中是由种类不同的色斑组合而成,是两种完全不同的可以区分的图案颜色.当蓝山雀搜索猎物时,青铜色白星花金龟在绿叶和树皮背景上都是暴露的,蓝山雀可以轻松定位发现.由远到近,蓝山雀能识别绿叶背景上的古铜色个体;但如果光照条件不好,树皮上的古铜色白星花金龟个体不能近距离识别.One species beetle,protaetia brevitarsis Lewis adults have purple-bronze and bronze body color,we compared the color composition and difference using bird visual model,and analyzed the recognition degree of the two dimorphic colors on green leaves and bark background.The results showed that in the eyes of the blue tit,the purple-bronze and bronze body colors of the adult were composed of different color spots,which were completely different and could distinguish the pattern colors.When the blue tit searched prey,the bronze beetle was exposed on the green leaves and bark background,the blue tit could easily locate them.From far to near,blue tits could identify purple-bronzed individuals on green leaves background,but were unable to identify purple-bronzed beetle on bark at close distance under poor light conditions.
