While we're no longer directly involved in managing Leafcutter bees, we still love these little guys! So while this particular page is undergoing redevelopment, here's some of the valuable info we presented here when we were actively managing the leafcutters:

Leafcutter bees are important pollinators for regenerative agriculture.  Primarily used for alfalfa in Saskatchewan, they increase seed set tremendously since alfalfa blooms are very tiny and do not pollinate as well from wind or other insects.  Alfalfa is a forage used widely as a winter feed source for livestock.  It is good for the soil as it has the ability to fix nitrogen.
