Figure 5

Comparison of spectroboard and integrating sphere measurements for Europe and Asia. (A) The histograms of the spectral position of reflectance maxima measured with spectroboard (wings not detached) are shown for four test regions: Mongolian Steppe (MS); Central Asia (CA); Adriatic Coast (AD); Central East European Plain (CE) from Ref.34. Number of specimens included in each region is indicated in each histogram in the right upper corner. (B) The spectra measured with spectroboard in normal incidence on museum samples averaged by the four test regions from Ref.34. In panel (C), the red line stands for the average of MS and CA regions, the blue line for the average of AD and CE regions (marked by broken lines in the left panel), the black diamonds show the spectral position of averaged reflectance maxima measured with the integrating sphere on the detached wings of the butterflies from the four samples regions: TZ, EF, EP, and EB.
