Data for: A hypothesis to explain polarization color vision in butterflies, with an example from the Australian Imperial Blue, Jalmenus evagoras

Richard Rabideau Childers
The Australian lycaenid butterfly, Jalmenus evagoras, has iridescent wings that are sexually dimorphic in both spectral reflection and degree of polarization, suggesting that these wing properties are likely to be important in mate recognition. We first describe the results of a field experiment showing that free-flying individuals of J. evagoras can discriminate between visual stimuli that vary in polarization content in a wavelength-dependent manner. We then present detailed reflectance spectrophotometry measurements of the polarization content...
