Finally, as already mentioned, quiet ultrasonic songs reduce the risk of interception by conspecific competitors, predators like insectivorous bats (1,3,7,8) and perhaps parasitoids (2). In moths, competition among males is strong, because many males are likely to be attracted around a pheromone-releasing female (1,14).…”

“…However, the risk of eavesdropping by competitors, predators, and parasitoids is high (1,2). To counteract this risk, various signalers (e.g., crickets, katydids, and moths) have changed the temporal and spectral characteristics of their signals and the timing of signaling (2)(3)(4)(5). In addition, several katydids are known to exploit sensory signals outside of the eavesdropper's sensory channel, e.g., vibrational signals (2,3).…”

Insects have evolved a marked diversity of mechanisms to produce loud conspicuous sounds for efficient communication. However, the risk of eavesdropping by competitors and predators is high. Here, we describe a mechanism for producing extremely lowintensity ultrasonic songs (46 dB sound pressure level at 1 cm) adapted for private sexual communication in the Asian corn borer moth, Ostrinia furnacalis. During courtship, the male rubs specialized scales on the wing against those on the thorax to produce the songs, with the wing membrane underlying the scales possibly acting as a sound resonator. The male's song suppresses the escape behavior of the female, thereby increasing his mating success. Our discovery of extremely low-intensity ultrasonic communication may point to a whole undiscovered world of private communication, using ''quiet'' ultrasound.acoustic communication ͉ hearing ͉ playback experiment ͉ receiver bias ͉ sound-producing organ

“…Similar to C. (Belwood, 1988(Belwood, , 1990Belwood and Morris, 1987;Morris et al, 1994;Römer et al, 2010). Eavesdropping seems to explain why some bush-crickets use such bewilderingly high principal carriers (Belwood and Morris, 1987;Falk et al, 2015;Montealegre-Z et al, 2006;Montealegre-Z et al, 2011b;Morris et al, 1994;Sarria-S et al, 2014). Several of these species using ultrasonic carriers and pure tones alternate their low-duty-cycle acoustic signals with substratum vibrations (Morris et al 1994, F. Sarria-S personal observations).…”

“…In bush-crickets it is speculated that tremulation functions to attract females whilst reducing the cost of acoustic eavesdropping by predators and also allowing for an alternative communication channel (Morris, 1980;Morris et al, 1994;Römer et al, 2010). Some species seem to have dramatically reduced their acoustic behaviour and adopted tremulation as a key modality for communication with females (Belwood and Morris, 1987).…”

Male bush-crickets produce acoustic signals by wing stridulation to call females. Several species also alternate vibratory signals with acoustic calls for intraspecific communication, a way to reduce risk of detection by eavesdropping predators. Both modes of communication have been documented mostly in neotropical species, for example in the genus Copiphora. In this article, we studied vibratory and acoustic signals and the biophysics of wing resonance in C. vigorosa, a new species from the rainforest of Colombia. Different from other Copiphora species in which the acoustic signals have been properly documented as pure tones, C. vigorosa males produce a complex modulated broadband call peaking at ca. 30 kHz. Such a broadband spectrum results from several wing resonances activated simultaneously during stridulation. Since males of this species do rarely sing, we also report that substratum vibrations have been adopted in this species as a persistent communication channel. Wing resonances and substratum vibrations were measured using a μ-scanning Laser Doppler Vibrometry. We found that the stridulatory areas of both wings exhibit a relatively broad-frequency response and the combined vibration outputs fits with the calling song spectrum breadth. Under laboratory conditions the calling song duty cycle is very low and males spend more time tremulating than singing

Behavioral responses of a parasitoid fly to rapidly evolving host signals

Animals eavesdrop on signals and cues generated by prey, predators, hosts, parasites, competing species, and conspecifics, and the conspicuousness of sexual signals makes them particularly susceptible. Yet, when sexual signals evolve, most attention is paid to impacts on intended receivers (potential mates) rather than fitness consequences for eavesdroppers. Using the rapidly evolving interaction between the Pacific field cricket, Teleogryllus oceanicus , and the parasitoid fly, Ormia ochracea , we asked how parasitoids initially respond to novel changes in host signals. We recently discovered a novel sexual signal, purring song, in Hawaiian populations of T. oceanicus that appears to have evolved because it protects the cricket from the parasitoid while still allowing males to attract female crickets for mating. In Hawaii, there are no known alternative hosts for the parasitoid, so we would expect flies to be under selection to detect and attend to the new purring song. We used complementary field and laboratory phonotaxis experiments to test fly responses to purring songs that varied in many dimensions, as well as to ancestral song. We found that flies strongly prefer ancestral song over purring songs in both the field and the lab, but we caught more flies to purring songs in the field than reported in previous work, indicating that flies may be exerting some selective pressure on the novel song. When played at realistic amplitudes, we found no preferences–flies responded equally to all purrs that varied in frequency, broadbandedness, and temporal measures. However, our lab experiment did reveal the first evidence of preference for purring song amplitude, as flies were more attracted to purrs played at amplitudes greater than naturally occurring purring songs. As purring becomes more common throughout Hawaii, flies that can use purring song to locate hosts should be favored by selection and increase in frequency.
