Acoustic communication is enabled by the evolution of specialised hearing
and sound producing organs. In this study, we performed a large-scale
macroevolutionary study to understand how both hearing and sound
production evolved and affected diversification in the insect order
Orthoptera, which includes many familiar singing insects, such as
crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly
establish phylogenetic relationships among the major lineages and
divergence time estimates within Orthoptera, as well as the
lineage-specific and dynamic patterns of evolution for hearing and sound
producing organs. In the suborder Ensifera, we infer that forewing-based
stridulation and tibial tympanal ears co-evolved, but in the suborder
Caelifera, abdominal tympanal ears first evolved in a non-sexual context,
and later co-opted for sexual signalling when sound producing organs
evolved. However, we find little evidence that the evolution of hearing
and sound producing organs increased diversification rates in those
lineages with known acoustic communication.
