"You'll be amazed at what you attract." After the blue orchard bees finish nesting, leafcutter bees

It relies on honey bees and leafcutter bees for pollination.
Leafcutter bees, used in commercial seed production, flew from their hives for a distance of two-thirds of a mile and back home.
A high density of leafcutter bees
(Megachile rotundata Fabricius) and hand pollination were used to ensure a high level of intercrossing among all selected plants.
, which line their nests with leaf fragments, pollinate our pea-type plants.
But there are an estimated 4,000 to 5,000 species of native bees in the continental United States--including bumblebees, carpenter bees, sweat bees, leafcutter bees
, alkali bees and mason bees such as the blue orchard bee--that also play an important role.
The effects of honeybees (Apis Mellifera L.) and leafcutter bees
(Megachile rotundata F.) on outcrossing between different cultivars of beans (Vicia faba L.) in caged plots.
