In chorusing species, sound frequency has been suggested as a decisive cue for male body size in female mate choice. However, few studies on the female choice of male song frequency have been conducted in cicadas, in which males of most species sing in chorusing groups to attract females for mating. In this study, we investigated female mate choice for song frequency and body size of males of a chorusing cicada, Mogannia formosana, by phonotaxis experiments using two-choice tests and field observation, respectively. The choice proportion of effective responses and the proximity to the stimulus were used to assess the phonotaxis preference. In the field, two types of males (copulating vs. random) were caught, and their body sizes were compared. In phonotaxis experiments, the results revealed that females showed a preference for low-frequency song by approaching the low-frequency stimuli to a significantly greater proximity. By comparing the body sizes of copulating vs. random males, no significant differences were found. However, the copulating males had significantly different body shapes, as expressed by pronotum width regression by body length, from those of random males. We concluded that the sound frequency of male songs and male body shape in M. formosana can be used as cues of mate quality during female mate choice within a chorus. Additionally, we suggest that females of this species might use multiple cues for mate choice in different ranges of communication and that body size might not be the sole criterion of mate quality. •Larger body-sized males have low frequency songs in cicadas.•Female cicadas approached low frequency stimuli with closer proximity.•Female cicadas did not show preference for larger body-sized males in the field.•The copulating males had significantly different body shapes.
