Dont find these in town often. Mostly further out in the boonies amongst the mesquite and scrub oak. These guys bite if you pick them up. Not super painful but youll know when they do it. This one was about 1.5” long. They get about twice this size fully grown.

The photograph doesnt do it justice. Its the darkest black, with a bright yellow streak down its back, with orange and red and green spots/stripes.
