Teleogryllus commodus Wikipedia
Male T. commodus use advertisement calling to attract mates. Inbred males call less often than out-bred males. Female T. commodus prefer males with a more frequent calling effort, so that inbred males suffer reductions in mating success. Male calling rate likely serves as an indicator to females of genome-wide heterozygosity and/or male condition.
