Berserkers are the only known female Locust. It is revealed in the first Gears of War book, Gears of War: Aspho Fields, that there is only one theoretically method of reproduction of Locust, which involves tying the female down, to stop her from blindly killing her mate, and then raping her.

During the Siege of Nexus, however, Spoiler:Damon notices that there are no Locust children, and questions whether the Locust are even capable of breeding at all.
