Q represents the left spermatheca which stores the sperms received from male during copulation

In the given figure, P represents the ovary of female cockroach, which consists of eight ovarioles (or ovarian tubules), each containing a row of developing ova. Q represents the left spermatheca, which stores the sperms received from male during copulation. R is the right collateral gland, whose secretions form the egg case of the ootheca. S is the gonapophyses, which serves as ovipositors.
