Since Blair Farms started raising alfalfa for seed we needed to have something reliable to ensure that the alfalfa flower were pollinated. Leafcutter bees are naturally occurring in our area and are small enough to do the job.
The alfalfa flower is spring loaded and when tripped will “thump” a honey bee on the nose. They are small in size and we build shelters for them to hold the boards they need to build nests. We keep the bees we need for next year’s crop and sell the rest. Leafcutter bees are measured in gallons and come out of hibernation around the second week in June; which is the time the alfalfa starts to bloom.
