Most insects reproduce oviparously, i.e. by laying eggs. The eggs are produced by the female in a pair of ovaries. Sperm, produced by the male in one testicle or more commonly two, is transmitted to the female during mating by means of external genitalia. The sperm is stored within the female in one or more spermathecae.
The gyne (/ ˈ ɡ aɪ n /, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens , whereas female workers are typically barren and cannot become queens.
A female Anopheles minimus mosquito obtaining a blood meal from a human host to support its anautogenous reproduction. In entomology, anautogeny is a reproductive strategy in which an adult female insect must eat a particular sort of meal (generally vertebrate blood) before laying eggs in order for her eggs to mature.

Most insects are oviparous, where the young hatch after the eggs have been laid. [4] Insect sexual reproduction starts with sperm entry that stimulates oogenesis, meiosis occurs and the egg moves down the genital tract. Accessory glands of the female secrete an adhesive substance to attach eggs to an object and they also supply material that ...
While the layout of internal genital ducts and openings of the female genitalia depends upon the taxonomic group that insect belongs to, the internal female reproductive system of all Lepidopterans consists of paired ovaries and accessory glands which produce the yolks and shells of the eggs.
The spermatheca (pronounced / s p ər m ə ˈ θ iː k ə / pl.: spermathecae / s p ər m ə ˈ θ iː s iː /), also called receptaculum seminis (pl.: receptacula seminis), is an organ of the female reproductive tract in insects, e.g. ants, bees, [1] some molluscs, Oligochaeta worms and certain other invertebrates and vertebrates.

In polyploid obligate parthenogens, like the whiptail lizard, all the offspring are female. [27] In many hymenopteran insects such as honeybees, female eggs are produced sexually, using sperm from a drone father, while the production of further drones (males) depends on the queen (and occasionally workers) producing unfertilized eggs.
Like most insects, the Lepidoptera are oviparous or "egg layers". [40] Lepidopteran eggs, like those of other insects, are centrolecithal in that the eggs have a central yolk surrounded by cytoplasm. The yolk provides the liquid nourishment for the embryo caterpillar until it escapes from the shell. [60]
