This is true but misses the point. Beekeeping is done for the sake of pollination: flowering fruit and crop pollination is where the money is at and the focus of the beekeeping industry. The vast majority of managed bee colonies in the US are used for this purpose. Bloom times are region and species specific. California almonds, for example, are usually the earliest bloom. Hives will be moved around based on those patterns. We're not talking 5, 20, or 100 hives, we're talking 10,000 to 250,000 hives at the high end. As blooms end the hives are moved to new orchards through out the growing season. Think bee hives on flat beds crisscrossing the country. At that scale replacing queens gets very expensive (and the hive may reject her anyway) due to veroa mite stress and the loss of the hive is common. Any honey not used by the bees along the way is sold to third parties which in turn sell it to consumers.
