Abstract

Oocytes of the parthenogenetic gall midge Heteropeza pygmaea assume an elongate shape when they mature inside the follicular epithelium. However, when the oocyte‐nurse chamber complexes grow without the regular follicular layer, they form spherical eggs. Such eggs may develop as far as the blastoderm stage. These findings indicate that the follicular epithelium is responsible for the shape of the egg but is not required for oocyte maturation and for initial steps in embryonic development.
