This small mouse lives in grassland. The ADW account says it prefers well-drained grassland and is most abundant in shorter grasses.
Its fur is grayish brown, with a white underside and a dark stripe along the middle of its back. The thin tail is shorter than the head and body.
It is nocturnal and eats seeds, flowers, grasses, cactus fruits, and insects such as grasshoppers. It may cache food underground for severe winters.
