Cardiodactylus
Behaviour:
Cardiodactylus is as well interesting for the peculiarity of its calling song: together with the other members of the tribe Lebinthini, they occupy an important part in the acoustic diversity of Eneopterinae. Based on the analysis of the frequency spectra, previous studies showed that Cardiodactylus species use high-frequency calling songs (Robillard & Desutter-Grandcolas 2004b), with a dominant frequency corresponding to the third harmonic of their song spectrum (Robillard et al. 2007), which places Cardiodactylus at the center of hypotheses of convergent evolution and phenotypic diversification toward high frequencies.
