The Sonoran mountain kingsnake, Lampropeltis pyromelana, is native to parts of Utah, Arizona, New Mexico, Nevada, and Mexico. It eats primarily lizards, but snakes and small mammals are also consumed. Females lay a clutch of three to six eggs during mid-summer. The Sonoran mountain kingsnake is found in mountainous regions, usually in woodland or rocky areas near water. Similar to many other Utah snake species, the Sonoran mountain kingsnake is active from late spring to early fall, but is inactive during the cold winter months.
