Song of the wild: acoustic behavior as additional character in the identification of crickets

Issue Date

Abstract

Recognition and identification process in some groups of crickets is a highly multipart method because it is done through auditory sounds rather than ocular recognition. Morphologically, crickets are identified based on the male tegminal veins and cells as well as the male and female genitalia. Most male crickets stridulate in order to attract and court a mate. The acoustic communication was considered ancestral to all acoustic Ensifera. Like many behaviors, a character evolves fast and diverges during the speciation process. Some part of the signal, however, is considered as more stable and can carry phylogenetic information. The acoustic signal produced by crickets follows a firm acoustical pattern that is species-specific which can be used for identification. The vibratory properties (sound frequency and amplitude) of a stridulum are directly related to the morphology and ultrastructure of the forewings. Thus, these characters are considered in the identification of Philippine Eneopterines.
