Offspring sex ratios produced by females of each species injected with the A. bipunctata Spiroplasma male-killer. Average proportions of female and male offspring are represented by black and grey shading respectively. Species bars are shown in order of increasing genetic distance from A. bipunctata (left to right). Number of matrilines and total number of offspring per species are given above each bar. The results of Fisher exact tests for the significance of sex ratio deviations away from equity are indicated above bars by asterisks. Coccinella septempunctata females produced no offspring.
