* Induced ovulator, so if mating does not occur no corpora lutea will form.
* In this situation, a post-oestrus period of 8-10 days occurs before the next oestrus.
* In a queen that has been mated, corpora lutea form and their lifespan is the same as gestation (~60 days).
* Thus, corpora lutea do not undergo luteolysis before pregnancy is established.
* In the event of pseudopregnancy (mated without conception), once formed the corpora lutea last ~40 days.
* The lifespan of the corpora lutea in a pregnant queen is extended to ~60 days by the action of pituitary prolactin.
* There is no need for a conventional 'maternal recognition of pregnancy'.
