Abstract excerpt
The eyes of flower-visiting butterflies are often spectrally highly complex with multiple opsin genes generated by gene duplication, providing an interesting system for a comparative study of color vision. The Small White butterfly, Pieris rapae, has duplicated blue opsins, PrB and PrV, which are expressed in the blue (λ(max) = 453 nm) and violet receptors (λ(max) = 425 nm), respectively. To reveal accurate...
