Foraging among the flowers

A few visitors to the Seaside Wild Buckwheat flowers (Eriogonum latifolium) in the Bodega Dunes on 26 August 2017:

 

Male Acmon Blue (Plebejus acmon) from below

 

Female Acmon Blue (Plebejus acmon) from above

 

A small wasp with big green eyes, possibly a bee hunter (Philanthus sp.)?

 

A beautiful iridescent blue wasp, possibly a spider wasp (Psorthaspsis sp.)?

If you can assist with the wasp identifications, let me know!
