“…For instance, of the 33 Bombycoidea caterpillar species known to produce defense sounds (Low, unpublished), only two species are reported to produce sounds as adults (e.g., Brehm et al, 2015) and the mechanisms used by the caterpillars and adults differ. Yack (2016) proposed that juvenile insects are under-represented in the literature on acoustic communication, and we argue that this pertains to defensive sound production as well. Juvenile insects are attacked by many predators and parasitoids, and as such there should be selective pressures to produce defense sounds.…”

“…Here we refer to an acoustic signal in the broadest sense, meaning a vibration that is airborne, waterborne (both commonly referred to as sounds), or solid-borne (commonly referred to as vibrations). For simplicity, hereafter we refer to all of these acoustic signals as "sounds" [see Hill (2014) and Yack (2016) for further discussion of acoustic signal nomenclature].…”

Survival Sounds in Insects: Diversity, Function, and Evolution

Insect defense sounds have been reported for centuries. Yet, aside from the well-studied anti-bat sounds of tiger moths, little is understood about the occurrence, function, and evolution of these sounds. We define a defense sound as an acoustic signal (air- or solid-borne vibration) produced in response to attack or threat of attack by a predator or parasitoid and that promotes survival. Defense sounds have been described in 12 insect orders, across different developmental stages, and between sexes. The mechanisms of defensive sound production include stridulation, percussion, tymbalation, tremulation, and forced air. Signal characteristics vary between species, and we discuss how morphology, the intended receiver, and specific functions of the sounds could explain this variation. Sounds can be directed at predators or non-predators, and proposed functions include startle, aposematism, jamming, and alarm, although experimental evidence for these hypotheses remains scant for many insects. The evolutionary origins of defense sounds in insects have not been rigorously investigated using phylogenetic methodology, but in most cases it is hypothesized that they evolved from incidental sounds associated with non-signaling behaviors such as flight or ventilatory movements. Compared to our understanding of visual defenses in insects, sonic defenses are poorly understood. We recommend that future investigations focus on testing hypotheses explaining the functions and evolution of these survival sounds using predator-prey experiments and comparative phylogenetics.

Review of the applications of principles of insect hearing to microscale acoustic engineering challenges

et al. 2023

When looking for novel, simple, and energy-efficient solutions to engineering problems, nature has proved to be an incredibly valuable source of inspiration. The development of acoustic sensors has been a prolific field for bioinspired solutions. With a diverse array of evolutionary approaches to the problem of hearing at small scales (some widely different to the traditional concept of “ear”), insects in particular have served as a starting point for several designs. From locusts to moths, through crickets and mosquitoes among many others, the mechanisms found in nature to deal with small-scale acoustic detection and the engineering solutions they have inspired are reviewed. The present article is comprised of three main sections corresponding to the principal problems faced by insects, namely frequency discrimination, which is addressed by tonotopy, whether performed by a specific organ or directly on the tympana; directionality, with solutions including diverse adaptations to tympanal structure; and detection of weak signals, through what is known as active hearing. The three aforementioned problems concern tiny animals as much as human-manufactured microphones and have therefore been widely investigated. Even though bioinspired systems may not always provide perfect performance, they are sure to give us solutions with clever use of resources and minimal post-processing, being serious contenders for the best alternative depending on the requisites of the problem.
