蛱蝶翅鳞片的超微结构观察

对我国东北地区典型常见蛱蝶科15属20种蝴蝶翅鳞片的超微结构进行了扫描电镜观察。结果显示：蛱蝶翅鳞片形态上可分为窄叶形、阔叶形和圆叶形3种，鳞片长65～135 μm，宽35～85 μm，间距48～112 μm。蛱蝶翅鳞片的超微结构可分为拱桥形、棋盘形和筛孔形3 种。拱桥形结构和棋盘形结构比较接近，二者与筛孔形结构差异较明显。在已观察的种类中，线蛱蝶属红线蛱蝶翅鳞片上的纵肋突起最小（200 nm×300 nm），闪蛱蝶属柳紫闪蛱蝶翅鳞片上的纵肋突起最大（590 nm×560 nm）。鳞片具有相似的形状、结构和排列，尤其是同属蝴蝶翅鳞片超微结构的形状和尺寸差异较小，表明它们之间的亲缘关系接近。

Ultrastructure of wing scales of Nymphalid butterflies (Lepidoptera: Nymphalidae)

Ultrastructures of wing scales of 20 species in 15 genera of Nymphalidae, typically common in northeast China, were observed by scanning electron microscopy. The wing scales of Nymphalid butterflies were in three shapes, namely angustifoliate shape, latifoliate shape and round-leaved shape. Scale length is 65-135 μm, width 35-85 μm, and distance 48-112 μm. The wing scale ultrastructures of Nymphalid butterflies observed can be divided into three types, namely arch bridge shape, chessboard shape and sieve pore shape. Arch bridge shape and chessboard shape are quite similar, but they are very different from sieve pore shape. Of the species observed, the size of the vertical gibbosities on the scale was smallest in Limenitis populi（200 nm×300 nm） and largest in Apatura ilia (590 nm×560 nm). The scales are similar in shape, structure and arrangement, and especially the differences in shape and size of the scale ultrastructure between the congeneric species are relatively less, suggesting their closer relationship.
