Lampropeltis splendida, known as the desert kingsnake, inhabits arid regions in the southwestern United States. It displays a striking pattern of black and yellow bands, aiding in camouflage among desert flora. This non-venomous snake is noted for its ability to prey on venomous snakes like rattlesnakes, exhibiting a unique immune adaptation.

Lampropeltis splendida, commonly known as the desert kingsnake, is native to the southwestern United States and northern Mexico. It is predominantly found in the states of Arizona, New Mexico, Texas, and extends into the Mexican states of Chihuahua and Coahuila.

The desert kingsnake inhabits arid and semi-arid regions, typically in desert scrub, grasslands, and open woodlands. These areas are characterized by hot, dry climates with sparse vegetation.

Lampropeltis splendida is a terrestrial species that plays a role as both predator and prey within its ecosystem. It primarily feeds on rodents, lizards, and occasionally other snakes, including rattlesnakes, thanks to its resistance to their venom. The species is adapted to a variety of microhabitats within its range, including rocky outcrops and sandy soils, where it can find cover and hunt for food.
