Probably a specialist on bindweed pollen, this group of bees runs from the Southwestern states down into southern South America. Note the expanded femurs of this male, interesting to speculate as to why. From the Packer Lab.

I love the form of this shot.

We have shots of both the male and the female of this Paraguayan species. The group occurs from the deserts of North America down into southern South America, the males have bulbous and rounded hind femurs, modifications seen in a number of bees species around the world.

Tim McMahon hunted down this Ancyloscelis in Costa Rica. The long tongue on this relatively small bee is a thing. This group as a whole has an affinity for flowers with long carollas. In particular, the love morning glories. Which is interesting, because you don't really see morning glories in the seed mix for pollinator plots.
