| Abstract: | Summary The surface structure of the compound eyes of 6 Drosophila species and 12 eye mutants of D. melanogaster were compared by scanning electron microscopy.D. melanogaster, D. simulans, D. hydei, D. funebris and D. virilis displayed hexagonal facets and differed only slightly in the distribution of bristles. D. lebanonensis displayed tetragonal facets.No obvious differences in surface structure of the eyes of colour mutants of D. melanogaster were found. Mutants with structural modifications of the eyes revealed irregular patterns of bristles, variations in bristle number and variations in facet shape, size and organization. The mutant spapol does not display clear-cut delineated facets. |
