What's That Bug? does not endorse extermination

More unidentified critters
I photographed one at a local park here in Southern Cal. Hoping you could help me identify them.
Thanks

Hi Rus,
You have outdone yourself with this Tarantula Hawk, Pepsis species photograph. The orange antennae are not something we are used to seeing. Curved antennae signify a female who has a powerful stinger. She uses it to paralyze tarantulas, the food for the larval wasps.

    This Pepsis is P. mildei, one of our two largest species in Southern California. At one time large numbers of P. mildei and P. thisbe could be seen frequenting the blooms of scalebroom plants in the canyons of Orange County.
