“…Each song contained the mean values of the following components of T. oceanicus calling song: pulses per long chirp, long chirp pulse duration, long chirp interpulse interval, short chirp pulse duration, short chirp interpulse interval, short chirps per song, pulses per chirp, intersong interval and frequency for songs recorded at 24-268C (terminology after Otte (1992); see Rotenberry et al (1996) for sonogram). This suggests a mutation among male T. oceanicus that invaded the Kauai population in 12-20 generations, assuming four generations per year and a shift between the very late 1990s and 2003.…”

Silent night: adaptive disappearance of a sexual signal in a parasitized population of field crickets

Sexual signals are often critical for mate attraction and reproduction, although their conspicuousness exposes them to parasites and predators. We document the near-disappearance of song, the sexual signal of crickets, and its replacement with a novel silent morph, in a population subject to strong natural selection by a deadly acoustically orienting parasitoid fly. On the Hawaiian Island of Kauai, more than 90% of male field crickets (Teleogryllus oceanicus) shifted in less than 20 generations from a normal-wing morphology to a mutated wing that renders males unable to call (flatwing). Flatwing morphology protects male crickets from the parasitoid, which uses song to find hosts, but poses obstacles for mate attraction, since females also use the males' song to locate mates. Field experiments support the hypothesis that flatwings overcome the difficulty of attracting females without song by acting as 'satellites' to the few remaining callers, showing enhanced phonotaxis to the calling song that increases female encounter rate. Thus, variation in behaviour facilitated establishment of an otherwise maladaptive morphological mutation.

“…Secondary loss of hearing is also common among some ensiferans, but apparently only among species that have also lost the ability to fly (Otte, 1992). This is not always coupled with the loss of sound production (muteness).…”

“…The presence of these specialized wing areas are taken as direct evidence for sound production and detection in both recent and fossil forms (Grimaldi and Engel, 2005; see below). There have been numerous studies of ''singing'' in katydids, crickets, and grasshoppers (Alexander, 1962;Otte, 1992;Gwynne, 2001). Probably the most familiar use of sound and hearing is by crickets to attract mates (Hoy and Robert, 1996).…”

ABSTRACT-Tympanal ears in insects are important for both intraspecific communication and for the detection of nocturnal predators. Ears are thought, based on modern forms, to have originated independently multiple times within insects and can be found on multiple regions of the body. Here we describe and document the exceptionally well preserved tympanal ears found in crickets and katydids from the Eocene Green River Formation of Colorado, which are virtually identical to those seen in modern representatives of these groups. These specimens are among the best preserved insect ears in the fossil record and establish the presence of ears in two major clades of Orthoptera 50 million years ago. Also discussed and evaluated are previously described insect ears from the Mesozoic and the implications of the findings of the present study for studying the evolution of ears within insects.

“…During each closing movement a portion of the anal edge of the left tegmen (the scraper) scratches a toothed vein (the file or pars stridens) on the underside of the right tegmen, resulting in a pulse of sound (WALKER, 1962;ALEXANDER, 1962a;WALKER & CARLYSLE, 1975). Acoustic communication is essential for the reproductive biology of crickets and several authors dealt with that subject (ALEXANDER, 1960(ALEXANDER, , 1962aHUBER et al, 1989;BAILEY, 1991;OTTE, 1992;DESUTTER-GRANDCOLAS, 1995, 1997.…”

ABSTRACT. Three isolated populations of the cricket Endecous itatibensis Rehn, 1918 had been analyzed to test the hypothesis of divergence in the calling song estridulation and to discuss its implications in the speciation process. The song registers were obtained from specimens in Corumbataí, Piraciacaba and Itatiba cities, state of São Paulo, Brazil. In the three analyzed populations, calling songs are composed by pairs of notes. Specimens from Corumbataí emit composed phrases with 3 to 18 pairs of notes, while those of Piracicaba and Itatiba have 1 to 3 pairs of notes. Inter-and intrapopulational variability in the frequencies of acoustic signals were detected. While recording the calling songs, other stridulations were registered, possibly from species of Orthoptera or Hemiptera. When the tapes were analyzed in the laboratory, it was verified that there was no overlap among the species' calling songs, in such a way that each species had their particular band of frequencies, avoiding interespecific acoustic competition.
