Supplementary Material

Supplementary Table 1 provides specific descriptions and representative photographs of mating behaviors as observed consistently across all male and female cultures. Behaviors involving motion are shown using video stills in time series. Supplementary Table 2 provides the total number of copulation opportunities and mean frequencies of copulation and other mating behaviors for individual asexual female cultures, as well as the totals for all cultures combined. The mean frequency with which no physical contact was observed between male-female pairs is also included for each culture and in total.
