Quick answer
The nine-banded armadillo is the only armadillo species widespread in the United States, recognised by its bony armour plates and ability to jump vertically when startled. It digs for insects and grubs, gives birth to identical quadruplets, and is expanding its range northward.

Armour and anatomy
Armadillos are covered in osteoderms — bony plates fused into bands with flexible skin between. The nine-banded armadillo cannot roll into a complete ball (unlike three-banded South American species). Strong claws excavate burrows and unearth beetle larvae and ants.
Reproduction and quadruplets
Nine-banded armadillos almost always give birth to four genetically identical young from a single fertilised egg. Delayed implantation allows breeding timing to match favourable seasons. Newborns have soft skin that hardens within weeks.
Range expansion
Once confined to Latin America, nine-banded armadillos crossed into Texas in the 1800s and continue spreading north and east across the United States, aided by milder winters and lack of specialised predators.
Ecology and health notes
Armadillos aerate soil through digging and eat crop pests, but they also raid gardens and can carry Mycobacterium leprae, the bacterium that causes leprosy — transmission to humans is rare but documented in close-contact settings.

- The nine-banded armadillo is the only armadillo species widespread in the United States, recognised by its bony armour plates and ability to jump vertically when startled.
- The nine-banded armadillo cannot roll completely into a ball. Three-banded armadillos in South America can.
- They are shy and rarely bite. Their main defence is fleeing or jumping straight up when startled.
- Bony plates protect against predators such as coyotes and dogs. Flexible bands allow movement while covering the back and head.

Conservation status of the Nine-Banded Armadillo
The nine-banded armadillo (Dasypus novemcinctus) is listed as Least Concern on the IUCN Red List. Least Concern (LC) is the IUCN's lowest-risk category, assigned to widespread, abundant species that have been evaluated and found not to be threatened. It does not mean a species faces no pressures — only that it is not currently at risk of extinction.
