Bálint, Zs., Moser, A., Kertész, K., Biró, L. P. & Parker, A. R.: A supposition: structural colours resulting from both natural and sexual selection on an individual wing in the butterfly genus Cyanophrys (Lepidoptera: Lycaenidae)

70 Zs. Bálint, A. Moser, K. Kertész, L. P. Biró & A. R. Parker Female-female dorsal wing surfaces - Female spectral properties were less divergent between species than in males, although there remained a (minor) degree of species-specificity (Fig. 24). Again, the one dual-peaked reflectance (of C. pseudolongula) revealed an additional peak in the UV region at 300 nm. Dual-peaked spectra The male and female of Cyanophrys pseudolongula, and the male of C. remus individuals revealed dual-peaked spectra, with peaks at around 300 and 500 nm respectively, of which the lower one displays a moderate 15% reflectance at normal incidence. The male C. pseudolongula spectrum was similar to that of C. remus regarding reflectance and number of peaks, but the two species differ in their maximum reflectivities. The female C. remus spectrum possessed a single peak at around 400 nm with higher (20%) reflectance, while the female C. pseudolongula possessed a bimodal spectrum. The second peaks of all dual-peaked spectra, however, always occurred at 300 nm or less, which was not significant for animal behaviour (see Discussion). Wavelength (nm) Fig. 21.
