Spectral absorption by screening pigment granules in the compound eye of butterflies (Heliconius)

Spectral absorption by screening pigment granules in the compound eye of butterflies (Heliconius) The spectral absorption by single granules, clusters and masses of granules of the screening pigment in the compound eye of the butterfly genusHeliconius was studied by microspectrophotometry. Most of the pigment granules were found to have an almost constant absorption in the wavelength region 300 to 700 nm. Other granules showed a maximal absorption either at about 450 or 560 nm. The maximum at 450 nm is suggested to be caused by xanthommatin and that at 560 nm by ommines. The pigment screen inHeliconius is concluded to be a neutral grey filter. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Comparative Physiology A Springer Journals

Abstract

The spectral absorption by single granules, clusters and masses of granules of the screening pigment in the compound eye of the butterfly genusHeliconius was studied by microspectrophotometry. Most of the pigment granules were found to have an almost constant absorption in the wavelength region 300 to 700 nm. Other granules showed a maximal absorption either at about 450 or 560 nm. The maximum at 450 nm is suggested to be caused by xanthommatin and that at 560 nm by ommines. The pigment screen inHeliconius is concluded to be a neutral grey filter.
