and its inability to hibernate. As of 2009, newspaper reports indicated the nine-banded armadillo seems to have expanded its range northward as far as Omaha, Nebraska in the west, and Kentucky Dam and Evansville, Indiana, in the east. In 1995, armadillos were only seen in the southern tip of South Carolina, and within two to three years, they had swept across most of the state. In late 2009, North Carolina began considering the establishment of a hunting season for armadillo, following reports that the species has been moving into the southern reaches of the state (roughly between the areas of Charlotte and Wilmington). Outside the United States, the nine-banded armadillo ranges southward through Central and South America into northern Argentina and Uruguay, where it is still expanding its range. Diet Nine-banded armadillos are generally insectivores. They forage for meals by thrusting their snouts into loose soil and leaf litter and frantically digging in erratic patterns, stopping occasionally to dig up grubs, beetles (perhaps the main portion of this species' prey selection), ants, termites, grasshoppers, other insects, millipedes, centipedes, arachnids, worms, and other terrestrial invertebrates, which their sensitive noses can detect through of soil. They then lap up the insects with their sticky tongues. Nine-banded armadillos have been observed to roll about on ant hills to dislodge and consume the resident ants. They supplement their diets with amphibians and small reptiles, especially in more wintery months when such prey tends to be more sluggish, and occasionally bird eggs and baby mammals. Carrion is also eaten, although perhaps the species is most attracted to the maggots borne by carcasses rather than the meat itself. Less than 10% of the diet of this species is composed by nonanimal matter, though fungi, tubers, fruits, and seeds are occasionally eaten. Behavior Nine-banded armadillos are solitary, largely nocturnal animals that come out to forage around dusk. They are extensive burrowers, with a single animal sometimes maintaining up to 12 burrows on its range. These burrows are roughly wide, deep, and long. Armadillos mark their territory with urine, feces, and excretions from scent glands found on the eyelids, nose, and feet. Males hold breeding territories and may become aggressive in order to keep other males out of their home range to increase chances of pairing with a female. Territorial disputes are settled by kicking and chasing. When they are not foraging, armadillos shuffle along fairly slowly, stopping
