“…We worked with the E. binotata species that lives on Viburnum lentago (Adoxaceae) host plants in Wisconsin, has nymphs with grey-green colouration and adult male signal frequencies of ca 165 Hz. Male signal frequency in this species is under weak directional selection, with females preferring signals of ca 185 Hz [46][47][48]. We preserved all individuals used in the trials below in 95% ethanol in the Rodríguez Lab collection.…”

Much is known about how the maternal environment can shape offspring traits via intergenerational effects. It is less clear, however, whether such effects may reach adult offspring sexual traits, with potential consequences for sexual selection and speciation. Here, we report effects of adult female aggregation density on the mating signals and mate preferences of their offspring in an insect that communicates via plant-borne vibrational signals. We experimentally manipulated the density of aggregations experienced by egg-laying mothers, reared the offspring in standard densities, and tested for corresponding differences in their signals and preferences. We detected a strong effect in male signals, with sons of mothers that experienced low aggregation density signalling more. We also detected a weak effect on female mate preferences, with daughters of mothers that experienced low aggregation density being less selective. These adjustments may help males and females find mates and secure matings in low densities, if the conditions they encounter correspond to those their mothers experienced. Our results thus extend theory regarding adjustments to the social environment to the scale of intergenerational effects, with maternal social environments influencing the expression of the sexual traits of adult offspring.

“…We finished the sequence by brushing each nymph three times with a paintbrush, to mimic a predator attack (following Ramaswamy and Cocroft 2009; Rodríguez et al. 2018a). Nymphs in the silent isolation treatment were simply recorded weekly for 30 minutes without any type of stimulation.…”

“…Enchenopa are communal plant‐feeding insects that communicate with plant‐borne vibrational signals throughout their life cycle, both as nymphs and as adults (Rodríguez et al. 2018b; Cocroft and Rodríguez 2005; Cocroft et al. 2008).…”

Social causes of variation in animal communication systems have important evolutionary consequences, including speciation. The relevance of these effects depends on how widespread they are among animals. There is evidence for such effects not only in birds and mammals, but also frogs and some insects and spiders. Here, we analyze the social ontogeny of adult mate preferences in an insect, Enchenopa treehoppers. In these communal plant‐feeding insects, individuals reared in isolation or in groups differ in their mate preferences, and the group‐reared phenotype can be rescued by playbacks to isolation‐reared individuals. We ask about the relative role of signaling experience and signaling practice during ontogeny on the development of adult mating preferences in Enchenopa females. Taking advantage of variation in the signal experience and signaling practice of isolation‐reared individuals, we find switch‐like effects for experience and practice on female mate preference phenotypes, with individuals having some experience and practice as juveniles best rescuing the group‐reared preference phenotype. We discuss how understanding the nature and distribution of social‐ontogenetic causes of variation in mate preferences and other sexual traits will bring new insights into how within‐ and between‐population variation influences the evolution of communication systems.
