Variation in male body size (wing length) among ten swarms. Swarms are ordered according to the per-capita mating probability. The mean wing length of each swarm is marked by a dot, and its color indicates the zone. The box whisker plots are explained in Figure 4. Overall mean body size (2.81 mm) is indicated by the horizontal line. Sample size per swarm ranged between 21 and 95.
