Late breaking new...this was identified by Don Harvey as Macrotera portalis (formerly in Perdita...now its own genus) Bee with Big Head. This is a Perdita...a male collected in Cochise County Arizona by Tim McMahon. Why such a big head. Unclear because sometimes in the same species have small heads. You would think people would have figured this out by now...it is so dramatic. But, no, the answer is no, and how exciting that such basic questions are there for the plucking.
