Notes:
Summary Rhabdom formation was examined at the EM level in two members of the Chrysomelidae with different patterns of open rhabdoms (Leptinotarsa decemlineata — ponticulus pattern; Crioceris asparagi — insula pattern). Rhabdom morphogenesis, especially that of the central rhabdomere system of R7 and R8 is slightly different in both species and does not reveal which of the two patterns is primitive and which is derived. A close spatio-temporal correlation was found in L. decemlineata between the occurrence of a transitory modified cilium and the beginning of rhabdomere formation. The significance of this finding and its possible functional implications for the development of insect photoreceptor cells are discussed.
