Taxonomists working with acoustic insects often rely heavily on differences in long-distance mating signals to identify species. Behavioral work has shown that female insects also rely on such cues. The extent to which species-level isolation may result from short-range cues distinct from the long-range cues has been comparatively neglected. Previous work has shown that the short-range courtship songs of the sister species Gryllus texensis and G. rubens (Orthoptera, Gryllidae) show significant divergence at the species level. Here I report the results of behavioral trials assessing mating isolation as a function of courtship.
