Ok, California Herps is saying that they don't recognize any subspecies of Lampropeltis zonata. Do you? Going on the assumption that the California Mountain Kingsnake is the only species in Northern California with red. There used to be a very healthy population in the Las Padres National Forest along the Arroyo Seco River. I've seen dozens there as a kid. Now, I really have no idea if that's truly the only kingsnake in Ca with red coloring, so this may info may be totally useless! Sorry if so! I was so surprised when we moved to the Sacramento area and all the kings were grey/white or black/white with an odd amount of creamy yellow every once in awhile. I had only seen the classic rings of the red/white/black version before and was a bit disappointed in the local kings

Now can we all say together, "Red touches Yellow-kills a fellow, Red touches Black-friend of Jack" Learned at a very young age while seeing an abundance of beautiful kings
