Hybrid acoustic phenotypes that overlap parents cannot persist in lacewings
Evidence
In some species of anurans, the acoustic niche hypothesis is only partially veriļ¬ed. For instance, Vasconcelos and Rossa-Feres (2008) have found that some anurans presented different advertisement calls that, combined with the physical calling sites, create an acoustic partitioning. Similarly Henry and Wells (2010) have found that in the Crysoperla carnea group (Insects, Neuroptera) sympatric species will partition acoustic niche space to reduce mating mistakes. Using an F1 hybrid between two very closely related sympatric species, Chrysoperla plorabunda and C. adamsi, they showed that acoustic discrimination between parents and hybrid is weaker and the hybrid phenotype overlaps with that of the parents, thus conļ¬rming that the intermediate song phenotype cannot persist. ā Almo Farina, Soundscape Ecology, 477
