Fig. 1.

(A) Proportion of females that mated and cannibalized for all trials. Females were more likely to mate with a familiar male (n = 81: n = 21 black/black, n = 20 black/brown, n = 20, brown/black, and n = 20 brown/brown; χ² = 5.64, P = 0.018). (B) Proportion of females that mated and cannibalized for all females exposed to more than one male (n = 59). Mating frequency depended on female treatment (χ² = 7.8, P = 0.05). Females mated significantly more with males with a familiar phenotype than an unfamiliar phenotype (χ² = 6.0, P = 0.014). Cannibalism frequency also depended on female treatment (χ² = 9.6, P = 0.023). Females cannibalized males with unfamiliar phenotypes significantly more than familiar phenotypes (χ² = 8.11, P = 0.004).
