Pepsis Tarantula Hawk
My son and I saw one of these this morning in Lake Forest, CA near a small stream. It was non-aggressive and wasn't bothered when I followed it to take pictures. It was about 1 1/2" long with bright orange wings. The body appeared black, but when the sun hit the wasp, the body appeared to be a brilliant royal blue.

Ron is correct. The blue reflections suggest genus Pepsis, but this is an old, very faded specimen and species ID is very unlikely. It is a female, though.
