The fungus forces its infected ant host to climb to an elevated branch on a tree so that the ant can die where conditions are better for the parasite. The parasite now needs its ant host to be eaten by a hoofed animal to restart the cycle - but this is a problem because hoofed animals eat grass, not ants. This kills the cricket but benefits the worm: The parasite can now emerge from its cricket host and begin the next stage of its life cycle, which involves finding a mate and releasing its parasite eggs into the water. Some brood parasites use mafia-like manipulation strategies: If the host parents reject the foreign egg, the brood parasite will come back and punish the hosts by destroying their entire nest.
