Lampropeltis zonata
A non-venomous colubrid endemic to western North America. A coral snake mimic in which each red crossband is flanked by two black bands, forming a triad, with white bands between triads. A black snout separates it from the Arizona mountain kingsnake.
Lampropeltis zonata is a non-venomous colubrid endemic to western North America, measuring 76 to 91 cm in the nominate form and 61 to 102 cm across the subspecies. It is a coral snake mimic banded in red, black and white, but entirely harmless. The pattern follows a strict rule: each red crossband is flanked by two black bands to form a unit called a triad, and successive triads are separated by a white, sometimes cream or yellow, crossband. Some individuals carry little red pigment, and the population on Isla Todos Santos lacks red bands altogether. The snout is black, or black with red markings, which separates it from the white-snouted L. pyromelana. Its range runs from a disjunct population in southern Washington through Oregon and California to northern Baja California, and the fact that most of it lies within California gives the species its common name. Seven subspecies are recognised, five in the United States and two in Mexico.

Humidity
40〜60%
Frozen-thawed mice; in the wild lizards, rodents and nestling birds
Create a gradient with a basking surface of 29-32C and a cool side of 21-26C. Aim for average humidity of 40-60 per cent, naturally a little higher on the cool side and at night. Raising humidity before a shed helps prevent retained skin. It is a montane species with cold winters in the wild, so apply a winter cooling period if you intend to breed it. It tolerates heat poorly, so watch the upper end of the range in summer.
A minimum enclosure of about 120 x 60 x 60 cm per adult is recommended, and larger is better. It is active and explores a great deal, so provide branches and hides on both the warm and cool sides. It is strong and an accomplished escaper, so use a front-opening enclosure that locks securely. It hides under rocks and logs by day, so place several tight ground-level hides.
It is carnivorous and in captivity is fed appropriately sized frozen-thawed mice. Always feed it alone in the enclosure. Lizards form a large part of the wild diet, so captive-hatched young can be reluctant to take mice and may need prey to be scented.
Kingsnakes are ophiophagous and will eat each other, so they must be kept alone. They are generally docile and easy to handle, but wash your hands after feeding so they do not mistake them for prey. Many individuals are nervous, so provide plenty of hides to let the snake settle.
The species is not listed in the CITES appendices, and it is neither a specified animal nor an invasive alien species under Japanese law. It is non-venomous and harmless to people, but escaped snakes are hard to recover, so keep the enclosure securely locked. Its red, black and white banding mimics venomous coral snakes, but the species itself is harmless. Collection is regulated in California and elsewhere, so choose captive-bred animals.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of California Mountain Kingsnake is Over 20 years in captivity. With proper care and nutrition, they can live a long and healthy life.
California Mountain Kingsnake typically reaches 76-91cm, 61-102cm depending on subspecies as an adult. Size may vary depending on care conditions and individual genetics.
California Mountain Kingsnake feeds on: Frozen-thawed mice; in the wild lizards, rodents and nestling birds. Aim for a balanced diet with appropriate feeding frequency.
