Abstract
The economic value of individual pollinators can be estimated as a product of five variables: single-visit pollination efficiency, daily foraging schedule and tempo, host fidelity, adult lifespan and the market value of the resultant fruit or seed.
The southeastern blueberry bee, Habropoda laboriosa (Hymenoptera: Apidae), sequentially provisions its subterranean nest cells with pollen and nectar obtained solely from species of blueberries, including commercial rabbiteye blueberry, Vaccinium ashei. Mature berries result from single visits by freely-foraging female H. laboriosa to 37–41% of virgin flowers visited.
Individual females visit more than 620 virgin V. ashei flowers for pollen to provision a single nest cell.
Over her entire adult lifespan, each female is estimated to visit nearly 50 000 V. ashei flowers, producing over 6 000 ripe blueberries with a fresh market value of $20 U.S.
