I thought I was seeing things at first, but as I lingered I watched three different workers bring in something contained in their pollen baskets within a span of two minutes. The substance was off-white, perhaps a bit grayish. I saw this today, around 3PM, it was about 60 F...on a beautiful late winter day. I noticed a post on a local group site that there were some bees going after some corn meal that a neighbor had set out for squirrels and wondered if my girls were finding something similar. Pollen on Feb. 22 in Colorado seems a bit farfetched.
