Acoustic analysis of the call of the two species exhibiting more cuticle light transmittance. (a-c) Phlugis poecila and (d-f) Copiphora gorgonensis. (a) Typical presentation of the call. (b) A single phonatome (closing stroke of the wings) in detail. (c) Spectral analysis of the phonatome in (b). Wide bandwidth of prevalent frequencies are apparent in the call of P. poecila. (d) Typical presentation of the call. (e) A single phonatome (closing stroke of the wings) in detail. (f) Spectral analysis of the phonatome in (e). Note higher tonal purity and harmonic content in the call of C. gorgonensis.
