Chapter 6 Acoustic Communication in the Nocturnal Lepidoptera
- Insect Hearing and Acoustic Communication 图书
- Pair formation in moths typically involves pheromones, but some pyraloid and noctuoid species use sound in mating communication. The signals are generally ultrasound, broadcast by males, and function in courtship. Long-range advertisement songs also occur which exhibit high convergence with communication in other acoustic species such as orthopterans and anurans. Tympanal hearing with sensitivity to ultrasound in the context of bat avoidance behavior is widespread in the Lepidoptera, and phylogenetic inference indicates that such perception preceded the evolution of song. This sequence suggests that male song originated via the sensory bias mechanism, but the trajectory by which ancestral defensive behavior in females—negative responses to bat echolocation signals—may have evolved toward positive responses to male song remains unclear. Analyses of various species offer some insight to this improbable transition, and to the general process by which signals may evolve via the sensory bias mechanism.
