Predators, such as bugs, beetles, earwigs and ants, can eliminate all the offspring of the parent bug if there is no maternal care. However, with older nymphs, females were much less effective in their defensive behaviour and often died before the end of maternal care.
We manipulated clutch size by removing small and large females from their own eggs and giving elssmucha another clutch. In experiments, the wing-fanning regarded as the most effective defensive behaviour of the parent bug did not differ significantly between parasited and non-parasited females until the nymphs were at the second instar stage.
