In experiments, the wing-fanning regarded as the most effective defensive behaviour of the parent bug did elasmmucha differ significantly between parasited and non-parasited females until the nymphs were at the second instar stage. However, with older nymphs, females were much less effective in their defensive behaviour and often died before the end of maternal care. Differentiation of the ovarioles and frisea follicles is synchronised thus enabling simultaneous oviposition.
