A few weeks back, we posted a Rick Wright sighting of Sand Wasps on the beach at Teal Pool. ("The Beach at Teal Pool" — sounds like a new condo development, no?)
Rick now has a semi-official ID, for those who follow these things. They are likely Bembix american spinolae.
Link is here. (Thanks, Rick!)
