Morphological constraints and nectar robbing in three Andean bumble bee species (Hymenoptera, Apidae, Bombini)
We report differences in foraging behavior of three Andean bumblebee species on flowers of Digitalis purpurea (Scrophulariaceae). Bombus atratus was a potential pollinator while B. hortulanus and B. rubicundus collected ...
