A Normalized absorbance spectra of Adelpha fessonia and A. californica long wavelength-absorbing rhodopsins measured by epi-microspectrophotometry. Experimental spectra of A. fessonia (n = 1 butterfly)(orange dots) and A. californica (n = 1 butterfly)(blue dots). LW rhodopsin template with peak absorbance at 530 nm (green line). B Normalized pupillary sensitivity of A. fessonia (n = 1 butterfly)(orange dots). The contributions of UV- (gray dotted line) and LW- (green dotted line) sensitive rhodopsins to the pupillary sensitivity are indicated by fits to a model that includes both UV (λmax = 355 nm) and LW (λmax = 530 nm) rhodopsins.
