Abstract: In most animal species, males produce conspicuous signals to attract mates such as loud and complex songs, bright and colorful body areas, or strong chemical lures. Females use those ornamented signals to choose a mate, and males also use them to compete with rival males. This simple scenario of males displaying to potential mates and rival males has dominated our understanding of sexual selection. However, ornaments that increase attractiveness to females also make males particularly vulnerable to eavesdropper predators that exploit those signals to home in on their victim. The existence of eavesdroppers makes clear that the web of communication is much more complex than textbook versions. This more realistic perspective of communication prompts the question, how do eavesdroppers shape the ecology and evolution of mating signals? Using frog-biting midges as a case study, and integrating bioacoustics, behavior, parasitology, and neurophysiology, this talk starts to unravel the evolutionary ecology of eavesdropping and how these non-target receivers affect the evolution of communication systems.
