This species is introduced in Virginia. It is distinguished by its grayish brown fur, distinctly black tipped ears and a black stripe that runs from the top of the tail to the rump. Adults are between 475 and 600 mm long (including the tail) and weigh between 1.3 and 3.2 kg. As other hares do, this jack rabbit reingests fecal pellets (coprophagy).

This species is the most widespread of the jackrabbit in the Unites States ranging throughout the western US and Mexico. This species was reportedly introduced into Loudon and Prince William Counties in the mid 1900’s by sportsmen. In 1960 to young jackrabbits from Kansas were released on Cobb Island (Northampton County) and since then, a breeding population has established itself there and in surrounding locales. Though in its natural habitat, this jackrabbit is found in the grasslands and deserts, it has adapted itself to living on the dunes and in beach grass in Virginia.
The diet of this species is made up of various types of vegetative matter. In the summer this includes fresh and herbaceous plants while in the winter the diet is mainly wood and dried herbaceous material.
