In the spermatheca, females of many insect species, including honeybee queens, can store gametes secreted by their sex partners.

<h3>What is Spermatheca ?</h3>

The female insect's spermatheca is an ectodermal structure that receives, stores, and releases sperm for egg fertilization. According to the species, spermathecae differ in size and shape.

They often come from the median oviduct, which is located close or on the genital chamber. A secretory duct called the ductus seminalis connects the spermathecal sac, also known as the receptaculum seminis, to the genital chamber, where the sperm are released.
The number of spermathecas varies among taxa, however the majority of insects only have one. Depending on the species of insect, the spermatheca has different morphologies. The spermatheca is composed of the spermathecal gland, duct, and reservoir. Both of these fluids feed the sperm.
