Given the costs of multiple mating, why has female polyandry evolved? Utetheisa ornatrix moths are well suited for studying multiple mating in females because females are highly polyandrous over their life span, with each male mate transferring a substantial spermatophore with both genetic and nongenetic material. The accumulation of resources might explain(More)
Highly variable within and across species, patterns of sperm use not only are often driven by post-copulatory sexual selection but can also be impacted by experimental design. In investigations of paternity bias using competitive double matings, the inter-mating interval is a temporal factor that can affect sperm use patterns if the first male’s sperm is(More)
