Fig. 4: The effect of male development temperature on the probability of an initial mating.

Heat-stressed males (red) were less likely to mate than control males (blue). Each point is the fraction of individuals that mated for a given isofemale line, with circle diameter proportional to sample size. Raw values and sample sizes are provided in Table S8. Note that values for 18 °C males are are typical of this species (Fisher et al. 2013).
