Knowledge about sense organs involved in vibratory communication in general, and of bugs in particular, is still limited. Unlike data on song repertoire and related behaviour, most experimental data on receptors are based only on investigations on a few model species. Morphology of leg vibratory receptor organs in stridulating bugs is lacking. Observations of mating behaviour (Fish and Alcock, 1973; Harris and Todd, 1980; Borges et al., 1987; Kon et al., 1988) and data on pheromone emission modulated by female singing (Miklas et al., 2003) demand detailed experimental investigations of multimodality at different levels of communication studies in Heteroptera.
