Abstract: | Summary A routine method for the preparation of pigment granules from insect eyes is reported. When viewed using an electron microscope, the isolated granules appear to be free from different structural elements, and there is very little contamination by membranous material. Ultrastructure and extinction spectra correspond to those found in situ.Acknowledgments. We thank Prof. Dr A. Fischer and Dr J. Rosenberg for their help in electron microscopic techniques.
