After pulling weeds with a group to help restore the bluff as a oak savannah for Urban Roots I looked at flowers for bumble bee workers and queens even though it had rained and saw what looked to me like a brown belted queen on Canada Thistle along with two much smaller red belted workers.
This observation is for the bee
After seeing no bumblebees during a walk around Central Park in Roseville and just one worker two-spotted at home at giant solomon seal and thinking they were finally home raising the first set of babies I went to the cooler shore of Lake Phalen and there were a few workers and this queen common eastern in the purple vetch at the north shore of Lake Phalen.
There were a few indigo bushes at Ames Lake with a couple of two-spotted worker bumble bee at them. But there is also acres of blooming purple vetch, and some penstemon. I saw at least two queen bumble bees plus more than ten workers in the patches of vetch that I checked out.
Likely multiple bees. But all ligatus females.
