sRGB Reflectances from Iberian butterflies

Data on wing reflectance (visible spectrum, mean standard RGB values (243.7= white, to 52= black) from 224 species of butterflies (Lepidoptera, Papilionoidea): 223 from the Iberian Peninsula and one (Cyclyrius webbianus) from the Canary Islands. Average of male and female, sample size as indicated in column n. The data from C. webbianus and Cacyreus marshalli are provided although these species were not included in our analyses of reflectance., The data were measured from digital images of set (collection) specimens taken in fixed conditions, with grey (average RGB) values standardized a posteriori to fit the scale white= 243.7= white, to black= 52. The data set includes the mean length of the forewing (mm) and the total areas (mm2) of the fore and hind wings., , # sRGB Reflectances from Iberian butterflies

Data on wing reflectance (visible spectrum, mean standard RGB values (243.7= white, to 52= black) from 224 species of butterflies (Lepidoptera, Papilionoidea): 223 from the Iberian Peninsula and one (*C. webbianus*) from the Canaries. Average of male and female, sample size as indicated in column n. The data from *C. webbianus* and *C. marshalli* were not included in our analyses of reflectance.

Text file, CSV format, columns delimited by periods, 225 rows (including headings) and 38 columns. Any means presented are weighted averages taking into account the areas of the parts involved. Wing reflectances refer to the parts of the wings exposed in a living butterfly (except FW\_AREA and HW\_AREA which are total wing surfaces).
