Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...

Abedus indentatus belostomatid male with eggs on its back. Males can be choosier than females. As an offering, males are capable of providing nuptial gifts secretions, which can be more expensive than female reproductive investment, [1] parental care, where the reproductive costs in males are higher than in females because they invest large quantities of resources and time after egg ...
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 ...
The reproductive system of female insects consist of a pair of ovaries, accessory glands, one or more spermathecae to store sperm, and ducts connecting these parts. The ovaries are made up of a variable number of egg tubes, ovarioles. Female insects make eggs, receive and store sperm, manipulate sperm from different males, and lay eggs.
One of the best-known examples of taxa exhibiting facultative parthenogenesis are mayflies; presumably, this is the default reproductive mode of all species in this insect order. [34] Facultative parthenogenesis has generally been believed to be a response to a lack of a viable male.
[2] [16] All bed bug reproduction occurs via traumatic insemination and the spermalege. The genital tract, though functional, [17] is used only for laying fertilized eggs. [3] The ectospermalege is a swelling in the abdomen, often folded, filled with hemocytes. The ectospermalege is visible externally in most bed bug species, giving the male a ...
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.
