A stallion mating with a mare. While horses in the wild mate and foal in mid to late spring, in the case of horses domestically bred for competitive purposes, especially horse racing, it is desirable that they be born as close to January 1 in the northern hemisphere or August 1 in the southern hemisphere as possible, [11] so as to be at an ...
A survey of damsel and dragonflies reveals characteristic cloacal pincher mating damage in 20–80 percent of the males, indicating a fairly high occurrence of sexual coupling between males. [71] [72] Male flour beetles engage in same-sex coupling to practice mating and to rid themselves of "old, less effective" sperm.

"I played a video of my horse whinnying that was sold and Sunny was left behind," she explained in the text overlay. "This was his reaction to [the first time] hearing him since he left," she added.
Therefore, mating before each oviposition is not necessary. There is no significant overall benefit for females in multiple matings; large females are at an advantage due to their ability to resist unnecessary matings. [21] As a result of multiple male mating, multiple paternities were observed in species as a result of convenience polyandry. [4]
"Mock mating" of desert fox pups. In one reported observation, a male spotted hyena attempted to mate with a female hyena, but she succeeded in driving him off. He eventually turned to her 10-month-old cub, repeatedly mounting and ejaculating on it. The cub sometimes ignored this and sometimes struggled "slightly as if in play".
Males then create a second territory, presumably in order to attract a secondary female to breed. Even when they succeed at acquiring a second mate, the males typically return to the first female to exclusively provide for her and her offspring. [24] Polygynous mating structures are estimated to occur in up to 90% of mammal species. [25]
Before mating and copulation, the male spider spins a small web and ejaculates on to it. He then stores the sperm in reservoirs on his large pedipalps, from which he transfers sperm to the female's genitals. The females can store sperm indefinitely. [7] Butterflies mating
