The diversification of animal communication systems is driven by the interacting effects signalers, signal receivers, and environment. Yet, critical role unintended like eavesdropping enemies, has been underappreciated. Furthermore, contemporary evolution signals rare, making it difficult to directly observe this process. Ormiine parasitoid flies rely exclusively on acoustic cues locate singing male orthopteran hosts. In Hawaii, selection imposed Ormia ochracea led recent rapid their local host crickets' song. We use complementary lab field experiments understand how receiver psychology (sensory cognitive mechanisms) evolves accommodate a new that host's signal. Receiver our understanding host-parasite coevolution communication, as sensory system establishes limits behavioral responses exert signals. demonstrate neural auditory tuning behavior O. have evolved in these differences likely facilitate detection novel songs. Further, recently songs are highly variable among males, prefer with particular spectral characteristics, enabling us predict eavesdroppers may shape song evolution. To knowledge, first evidence for an eavesdropper. Our work links systems, signals, behavior, heeding call better integration mechanisms receivers into communication.
