There is a trend of female hares (Jills) being larger than male hares (Jacks).

Lepus nigricollis - Regardless of location, female L. nigricollis tend to be larger than males.

Lepus califomicus - In Kansas, sexual dimorphism exists in mass and length of adults; females are larger than males. As the breeding season begins, difference in mass between sexes increases until a maximum is reached in mid-summer. Toward the end of the breeding season in late summer, males begin to gain mass and females to lose mass. After the breeding season, mass is nearly the same for both sexes.
