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.
Gyne... was lethargic and unable to fly, though it wasn't cold. Also seemed to be wet/coated with something. Didn't seem to be doing too well - was doing that little twitchy front foot behavior I tend to see in Hymenoptera that have ingested pesticides. Left her on a flower.
Flagged as rare on eBird... they're very common at this location but I suppose it's still a bit early.
