— The main visual pigment of blowflies (xanthopsin, Vogt, 1983 Z. Naturforsch. 38c ,329–333) photoconverts into two thermostable metaxanthopsin states M and M'(e.g. Stavenga et al. , 1984 Photochem. Photobiol. 40 ,653–659). The fluorescence spectra of the two photoproducts were studied by microspectrofluorometry in vivo. The emission spectra of M and M'are very similar and peak at 660 nm. The excitation spectra of M and M'have peak wavelengths at Λ max ' 584 nm and = 568 nm respectively.
