S(λ) gives the name of the photoreceptor class, as derived from the wavelength range of the spectral sensitivity, UV ultraviolet, V violet, dB double-peaked blue, B blue, G green, dG blue-suppressed green, PR pale-red, DR deep-red (Wakakuwa et al. 2007)
aThe anatomically defined photoreceptors R1 and R2 either contain the UV and B rhodopsin or the B and UV rhodopsin
