Reproduction

When mating, females attract males by calling to them. The duration of the female call is ten to fifteen minutes. A male will hear the call and respond to it by running to and jumping around the female. The female then squats down, and the male performs 12-24 thrusts. The entire process of mating lasts about fifteen seconds.
