 Myrmecia ants deter many potential predators due to their sting . The blindsnake Ramphotyphlops nigrescens consumes the larvae and pupae of Myrmecia , while avoiding the potent sting of the adults , which it is vulnerable to . The short @-@ beaked echidna ( Tachyglossus aculeatus ) also eats the eggs and larvae . Nymphs of the assassin bug species Ptilocnemus lemur lure these ants to themselves by trying to make the ant sting them , by waving its hind legs around to attract a potential prey item . Body remains of Myrmecia have been found in the stomach contents of the eastern yellow robin ( Eopsaltria australis ) . The Australian magpie ( Cracticus tibicen ) , the black currawong ( Strepera versicolor ) , and the white @-@ winged chough ( Corcorax melanorhamphos ) prey on these ants , but few are successfully taken .
