问题 单项选择题

山兰风蝶是澳大利亚的一种常见蝶,其雄性翅膀的颜色为异常亮丽的蓝色,但周边镶嵌山黑色,具黑色部分越黑,蓝色部分就越艳丽,在求偶竞争中也就越有优势。专家们以前认为,这是由于其中的黑色素吸收了大部分入射光所致。但现在发现,这种蝴蝶不只是通过化学方式,更是通过物理方式,即一种特别的光学手段宋使其黑色部分显得更黑,因为它包含黑色素的微细鳞片结构能“捕捉”住光,由此创造出一种比黑色还黑的“超黑”。 对材料的理解不当的一项是( )。

A.在求偶竞争中,山兰风蝶依靠翅膀周边镶嵌的“超黑”色彩,能够更有效地吸引异性蝴蝶。

C.山兰风蝶主要是通过物理方式——种特别的光学手段——来使其黑色部分变成“超黑”。
