孤雌生殖的瘿蚊Heteropeza pygmaea卵母细胞在滤泡上皮内成熟时呈细长形。当卵母细胞-保育室复合体在没有规则卵泡层的情况下生长时，它们形成球形卵。这些卵可以发育到胚盘阶段。滤泡上皮似乎负责卵子的形状，但可能不需要卵母细胞成熟和胚胎发育的初始步骤。
Oocytes of the parthenogenetic gall midge Heteropeza pygmaea assume an elongate shape when they mature inside the follicular epithelium. 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. The follicular epithelium seems responsible for the shape of the egg but may not be required for oocyte maturation and for initial steps in embryonic development.
