The polytrophic ovarioles of Panorpa communis are differentiated into a terminal filament, germarium and vitellarium. The germarium contains cystoblasts and germ cell clusters at early stages of their differentiation. At the base of germarium the cystocytes become morphologically diversified. One of the central cells of the cluster becomes the oocyte while the remaining cystocytes differentiate into nurse cells. The presence of intercellular bridges between the oocyte and the nurse cells and those connecting the nurse cells was revealed by rhodamine-phalloidin staining of F-actin. The derivatives of one cystoblast - three nurse cells and oocyte are enveloped by follicular epithelium, thus forming the egg chamber. The follicular epithelium is morphologically diversified.
普通蝎蛉的多滋式卵巢管分化为端丝、生殖区和卵黄区。生殖区在分化早期包含成囊细胞和生殖细胞簇。在生殖区基部，囊细胞在形态上变得多样化。簇中的一个中央细胞成为卵母细胞，而其余囊细胞分化为滋养细胞。通过罗丹明-鬼笔环肽对F-肌动蛋白进行染色，揭示了卵母细胞与滋养细胞之间以及连接滋养细胞的细胞间桥的存在。一个成囊细胞的衍生物——三个滋养细胞和卵母细胞被卵泡上皮包裹，从而形成卵室。卵泡上皮在形态上是多样化的。
