| "Hispid" refers to the coarseness of this pocket mouse's fur. Hispid Pocket Mice are larger and more robust than other pocket mice in their range, and like the others, they are solitary except in the breeding season. The gestation period is not known, but females in the northern part of the range may have two litters of 4-7 young a year. In the southern part of the range, mating activity has been seen year-round.
