Blastophthorus, egg laying takes about 40 sec for the first half of the egg and about a quarter of a second for the second half. The whole process is dependent on the plasticity of the shell (Fig. 6), and because egg laying may take only a fraction of a second in some forms, it may easily be missed. A number of factors can affect oviposition. In C. elegans, for instance, the absence of food, caused by removing the hermaphrodite from its food source to a buffered, bacteria-free medium, stops egg laying and leads to a virtual "bag of worms" in which the embryos within this hermaphrodite continue to develop and hatch but cannot escape from their parent (Chalfie and White, 1988).
