Megachile?

This guy never really stopped. It would land on a flower and take off again immediately.

Megachile female
leaf-cutter

I believe this is Megachile (Pseudocentron) pruina.

Note the description of var. pinguis, described from coastal Texas (Galvesten), in Mitchell, 1937, Trans. Amer. Ent. Soc. 63:68.

Variety pinguis, treated as a subspecies in the Hurd (1979) Red Catalog, has, "Pubescence of face, cheeks, pleura, propodeum, legs and abdomen basally, fuscous" as opposed to largely white in typical pruina according to the key on p. 64.

If this ID is correct it is apparently a first record of the species from Louisiana and the first record of the subspecies from outside Texas.

I am not aware of other Megachile in the region with this hair pattern, in particular the extensively fuscous puescence. Comments welcome!
