Song et al. inferred that stridulatory wings and tibial ears co-evolved in a sexual context among crickets, katydids, and their allies, while abdominal ears evolved first in a non-sexual context in grasshoppers, and were later co-opted for courtship. They found little evidence that the evolution of these organs increased lineage diversification.
