Scolopendra heros
Another of the many color variants of Scolopendra heros Girard, 1853, the largest-bodied centipede in North America, growing up to 7 inches or so. It ranges from Kansas & southern Missouri to Louisiana, and westward through Texas & New Mexico/eastern Colorado to the Colorado River in Arizona. It ranges southward about 1/4 of the way into Mexico, and has not been authentically found west of the Colorado River in California.

 
S. heros color variant
Wow, this one pictured here is the super rare striped version. I have only seen a couple photos of these. Much more common is the banded version from SE AZ, with wider black bands and orange first segments. Of course the standard "arizonensis" has a solid orange body, black head and first 2 segments as well as black last 3 segments.

Amazing--i think I saw this e
Amazing--i think I saw this exact same centipede--I was climbing Mount Ajo in Organ Pipe early last April and saw this guy or one just like him and nearly had a heart attack--HUGE! The ranger there said that in southern Az., these guys come under the door into your house all the time....

 
We know the feeling
We were too nervous to take decent photos! Suppose you would get calmer after several encounters.

 
dangeris or not
i would like to know if they are or not.

 
Possible Hazard
I heard from a program on the Discovery Channel the Centipedes have 2 poisonous stingers near their heads. One of this size could be highly dangerous to small children, and only slightly less so to adults. It would be best to just leave all Centipedes alone.
