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 nectar by robbing through
holes. We attribute behavioral differences to physical constraints. B. atratus has a
longer glossa and a larger body size and is able to reach the nectaries, whereas B.
hortulanus and B. rubicundus have shorter glossae and smaller bodies and probably
must rob nectar through holes at the base of flowers.
