Fly rhabdomeres twist in vivo

Summary

Electron-microscopic examination shows that the rhabdomeres of the visual cells ofMusca domestica twist in the manner typical ofCalliphora erythrocephala andDrosophila melanogaster. More-over, it can be demonstrated that the rhabdomere section shown by Ribi (1979, Fig. 2) is from a twisting rhabdomere. Rhabdomere twist appears to be a wide-spread feature of dipteran eyes.

We are most grateful to Dr. Ribi for his readiness to allow us access to his original documents, for demonstrating the techniques he used, and for providing us with a preparation of theMusca domestica eye that he had treated and embedded. Dr. Marguerite Biederman-Thorson has translated the manuscript into English.
