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.
