Brief SummaryRead full entry
Alfalfa leafcutter bees are 1/4 to 3/8 of an inch long. They are black with whitish or yellowish bands on their abdomens. Alfalfa leafcutter bees have been used as commercial pollinators of alfalfa for over 50 years. They also pollinate carrot (Daucus carota), onion (Allium spp.), and wild blueberry (Vaccinium spp.) crops as well as sweet clovers (Melilotus spp.), white clover (Trifolium repens), and some wild mints (Mentha spp.). Stiff hairs on the bee's abdomen collect pollen during foraging. This pollen is then inadvertently transferred to other flowers while the bee continues to forage.
