[Digger Wasp] now thought to be a Cuckoo Bee

Our Bridal Wreath shrub has come into bloom and is attracting many insects including this one.  I think it is some variety of Digger Wasp but I am not sure which - possibly ectemnius cephalotes.


EDIT:  Thanks to @Chamaeleo for the identification.


Bright sunshine all day today after a cold night.
