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)

Structural colours in Cyanophrys (Lepidoptera: Lycaenidae) 69 Table 1. Summary of measurements for the five Cyanophrys species Species Sex (number of Type of reflec­Figures (reflectance peak Species individuals) tance spectrum and reflectivity) Cyanophrys acaste male (4) unimodal 485 nm / 36% Cyanophrys acaste female (2) unimodal 450 nm / 26% Cyanophrys amyntor male (5) unimodal 445 nm / 22% Cyanophrys amyntor female (1) unimodal 450 nm /31% Cyanophrys argentiniensis male (1) unimodal 450 nm / 15% Cyanophrys pseudolongula male (5) bimodal 250 nm / 8% and 440 nm / 22% Cyanophrys pesudolongula female (3) bimodal 310 nm /12% and 510 nm /31% Cyanophrys remus male (5) bimodal 290 nm / 7% and 490 nm / 17% Cyanophrys remus female (3) unimodal 480 nm / 30% RESULTS Intraspecific reflectance comparisons Cyanophrys remus individuals of the same sex produced identical spectra from their dorsal wing surfaces according to their sexes (Fig. 21). Male-female dorsal wing surfaces - The spectral properties of conspecific male and female dorsal wing surfaces were dissimilar. They always differed in the position of their spectral wavelength peaks and the intensity of their reflectances. In general, males were less reflective but possessed more saturated colours with narrower wavelength peaks, while the females revealed broader reflectance peaks. The only exception was Cyanophrys acaste, whose males were far more reflective than the females. However, amongst the five Cyanophrys species examined, C. acaste exhibited the brightest male reflectivity (Fig. 22). Male-male dorsal wing surfaces - Spectral properties of the male dorsal wing surfaces of different species were also dissimilar (Fig. 23). Beside the different wavelengths at which the peaks occur, and different reflectance values for the peaks, there were differ­ences in the shape of the reflectance peaks too. The species C. acaste and C. pseudolongula displayed steep reflectance peaks compared to the broader peaks of the other three species examined. Although some species revealed a dual-peaked spectra, the second peak always lay in the ultraviolet (UV) region at or below 300 nm. Annls hist.-nat. Mus. natn. hung. 101, 2009
