I defined the dominant wings in moths as upper side of wing when it is at rest, and folds wing over its back. In first year, I found the wild moths included some right wing dominant species, some left ones, and non-dominant wing species. In second year I focused on a left wing dominant species, Adoxophyes honmai, of rearing strain. First moth individuals flied and landed, then I checked which side of forewing was folded into upper position. Consequently each individual set one regular side of forewing into upper position, other side into lower. While the dominant forewing between full-sib offspring was randomly different each other, as the ratio was 1:1 (left: right). Moreover, I examined side-dominancy between fore- and hindwing in each specimen. That was well-correlated between them, but only 20% of them had inconsistent side dominancy between wings. Thus, such inconsistency of dominant wings may be caused by some accident, for example attacked by natural enemies and so on.

我将飞蛾的主导翅膀定义为静止时翅膀的上侧，并将翅膀折叠在背部。第一年，我发现野生蛾类包括一些右翼优势种、一些左翼种和非优势种。第二年，我重点研究了饲养品系的左翼优势物种 Adoxophyes honmai。 第一个飞蛾个体飞行并着陆，然后我检查前翅的哪一侧折叠到上部位置。因此，每个个体将前翅的一侧固定在上部位置，另一侧固定在下部位置。而全同胞后代之间的优势前翅是随机不同的，其比例为1：1（左：右）。此外，我还检查了每个标本的前翅和后翅之间的侧面优势。他们之间有很好的相关性，但只有 20% 的人在两翼之间的边路优势不一致。因此，这种优势翅膀的不一致可能是由一些意外造成的，例如受到天敌的攻击等。
