雄蟋蟀在交配时转移给雌蟋蟀的精子包囊，包括一大块凝胶状的部分（精子鞘），在交配后被雌蟋蟀取出并消耗掉。在其他北美蟋蟀种类中，精子包囊仅由一个含有精子的小壶腹组成。在本研究中，我们研究了精包大小在苏氏天竺鼠生殖行为中的作用，以及与提供更复杂的精包相关的成本。连续接触受情期雌蜂的雄性供体供体平均交尾间隔为3.25 h；这一时期相对于其他蟋蟀来说要长一些。24 h后雄虫产生的精囊重量与相同雄虫产生的精囊重量无显著差异；雄性显然在随后的交配中保持不变的投资。雌虫消耗精鞘的时间随体重的增加呈线性增加。
The spermatophore that a male cricket of Gryllodes supplicans transfers to the female during mating, includes a large gelatinous portion (spermatophylax) that is removed and consumed by the female after mating. In other North American cricket species, the spermatophore consists solely of a small sperm-containing ampulla. In this study, the role of spermatophore size in the reproductive behaviour of G. supplicans was examined, along with the costs associated with the provision of a more complex spermatophore. The mean intercopulatory interval of male G. supplicans that were allowed constant access to receptive females was 3.25 h; this period is long relative to those of other crickets. The estimated weight of spermatophores produced by males did not differ significantly from that of spermatophores produced by these same males 24 h later; males apparently hold constant their investment in subsequent copulations. The time taken by females to consume the spermatophylax fully increased linearly with the weight...
