 note = {application/pdf, The compound eye of the butterfly Papilio xuthus is composed of three spectrally distinct types of ommatidia. We investigated the blue and double-peaked green receptors that are encountered distally in type I and III ommatidia, by means of intracellular recordings, in vivo fluorescence microscopy, and histology. The blue receptors are R1 and/or R2 photoreceptors; they contain the same mRNA encoding the opsin of the blue-absorbing visual pigment. However, here we found that the sensitivity in the UV wavelength region strongly depends on the ommatidial type; the blue receptors in type I ommatidia have a distinctly depressed UV sensitivity, which is attributed to lateral filtering in the fused rhabdom. In the main, fronto-ventral part of the eye, the R3 and R4 photoreceptors of all ommatidia contain the same set of two mRNAs encoding the opsins of green-absorbing visual pigments, PxU and PxL2. The spectral sensitivities are double-peaked, but the UV sensitivity of the R3 and R4 photoreceptors in type I ommatidia appears to be reduced, similar to that of the co-localized blue receptors.},
