I live in S.E. Michigan and my hives have been busy. I live in close proximity to a number of large fallow fields of white & yellow sweet clover and mowed fields of Dutch clover with unusually intense blooms this year. In walking these areas this past sunny week, I am hard pressed to find more than a random honey bee or 2. Plenty of bumble bees though. In years past, the fields were buzzing. What is up?
