Abstract
The amphipod, Hyalella azteca (hereafter H. azteca), is abundant in Midwestern USA, where it produces many broods in one breeding season. Two different samples of H. azteca were collected from Lake Itasca, MN and stored in the lab for at least 24 hrs. Precopulate pairs were then measured and a linear regression was performed. No significant linear correlation was found, showing that they pair with no size selection. Five precopulatory pairs were observed where one female was presented with two males of differing size. The larger male was included in the precopulatory pair only 3 out of 5 times, suggesting little to no male competition.
