 Some species of cricket which are parasitzed by "O. ochracea" have evolved methods to avoid infestation.For example, some members of the prey cricket "Teleogryllus oceanicus" have a mutation called flat wing, in which the sound-producing structures of the male forewings are erased.The flat wing was first observed in 2003 on the Hawaiian island of Kauai, and was also found on neighbouring Oahu two years later.
