摘要：

We examine the relationship between a male's body size and the length of his sperm in the yellow dung fly Scathophaga stercoraria (L). Sperm length could affect the outcome of sperm competition, which is known to be important in this species. Sperm were monomorphic but varied significantly amongst males. However, there was no significant relationship between a male's size and the mean length of his sperm. We conclude that variation in sperm length will not affect conclusions about sperm competition drawn for S. stercoraria
