Small nesting aggregation, ~35 nests, in a sandy powerline ROW along a trail. Not far from the Colletes validus aggregations that emerge a couple of weeks later.
Additional site photos added for the GNBees Project. I forgot to take one pointing upwards but it was in a completely open area, no canopy cover.
there were a number of these on this warm spring day swarming in the cedar tree
On oxeye or woodland sunflower.
On bushy white aster.
