摘要同性性行为（SSSI）在许多动物群体中被观察到，并引起了进化论者的兴趣。本文综述了鳞翅目昆虫SSSI行为的研究进展，并讨论了可能解释这些行为的进化假说。SSSI已被记录在25个物种的男性和一个物种的角色互换种群的女性。已报道的SSSI有四种类型：蛹守卫、求偶、交配尝试和交配。虽然这些假设不能用有限的数据进行检验，但有证据表明，在一些鳞翅目昆虫中，SSSI可能是由于选择对其他雄性施加成本而产生的，或者可能是性选择的副产品，有利于表现出高性意愿的个体。与这两个假设一致，在17个物种的交配系统是已知的，有激烈的竞争，为配偶的性别表现SSSI。我们建议在鳞翅目SSSI的研究路线。
Abstract Same-sex sexual interactions (SSSI) have been observed in many animal groups and have intrigued evolutionists. In this paper, reports on SSSI in Lepidoptera are reviewed and evolutionary hypotheses that could explain these behaviors are discussed. SSSI have been documented in males of 25 species and in females from role-reversed populations of one species. Four types of SSSI have been reported: pupal guarding, courtship, copulation attempt, and copulation. Although the hypotheses cannot be tested with the limited data, evidence suggests that in some Lepidoptera SSSI could result from selection for imposing costs on other males, or could be a by-product of sexual selection favoring individuals that exhibit high sexual willingness. In agreement with both hypotheses, in the 17 species whose mating systems are known, there is intense competition for mates in the sex exhibiting SSSI. We propose lines of research on SSSI in Lepidoptera.
