Hatch rates of eggs laid by females of the species injected with the A. bipunctata Spiroplasma male-killer. Average proportions of eggs that hatched are shown by black bars. Proportions of unhatched eggs are divided between those that showed no signs of embryonic development (in white) and those that became grey and died shortly before hatching (in grey). 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.
