Figure 1. Fecundity of winged and wingless males. a) The average number of females mated by wingless (open bars) and winged (black bars) males on every other day of the experiment. b) The average number of females fertilized by winged and wingless males. c) The relationship between cumulative rate of reproduction (∑l_xm_x where m_x = average number of females fertilized/male) and wing morph in individual fecundity experiments. Error bars are +1 SD.
