I noticed today they were bringing in two different colors of yellow pollen; light yellow and dark yellow. The light is smooth sumac( on it's second bloom ) and goldenrod. Staghorn sumac is also in bloom and the kudzu is finally in full bloom, thanks to plenty of rain the last two weeks. Although I haven't seen them on the kudzu at all. I have a location in up north with soybeans a mile away in two directions, need to check that out. I'm hoping all this will get them built up good for winter. We never lack for pollen, just nectar.
