Technical Abstract: Pollination efficacy of the oligolectic bee Ptilothrix bombiformis was measured as the number of pollen grains delivered to virgin Hibiscus stigmas. Such specialized bee foragers are often assumed to be highly efficient pollinators. Intriguingly, however, we discovered females fight over host blooms, increasing stigmatic loads, and thus host pollination success.
