Golden Alexander's flowers are shallow and easily accessed by small bees with short tongues such as the Mining Bees (Andrenid spp.) shown in photos 1 - 3.
Blue False Indigo flowers are much more difficult to access by small bees but are easily accessed and preferred by bumble bees. The bee in photos 4 - 6 is a Brown-belted Bumble Bee queen (Bombus griseocollis).
