[Dimensionless criteria of the time for the development of Drosophila embryos, larvae and pupae and of bee embryos in tables of normal development].

The work reported in this paper constitutes the first attempt to apply the method of the dimensionless characteristic of development duration (Dettlaff and Dettlaff, Arch. Biol. (Liege), 1961, vol. 72, pp. 1-16) to insects, specifically Drosophila melanogaster and Apis mellifera.
