Bumble bee banquet: Genus‐ and species‐level floral selection by Midwestern Bombus

Jessie Lanterman Novotny; Andrew Lybbert; Paige Reeher; et al. Ecosphere 2023. doi:10.1002/ecs2.4425

Other claims from this paper (14)

Observation Bombus selected flowers nonrandomly.
Observation The most strongly preferred plants included Asclepias, Cirsium and Convolvulaceae.
Observation Other strongly preferred plants included Dipsacus, Echinacea and Monarda.
Observation Penstemon and Silphium were among the strongly preferred plants.
Observation Few Fabaceae were highly selected, including Baptisia, Trifolium pratense and Vicia.
Observation Securigera varia was preferred only during peak bloom.
Observation T. hybridum and Melilotus were not preferred by bumble bees.
Association Bumble bee diets differed among habitats.
Observation In restored meadows bumble bees selected native planted species including Monarda, Asclepias and Echinacea.
Association Seasonal diets and preferences shifted with plant phenology.
Method / resource Rarefaction detected almost all summer diet plants of three common Bombus species.
Method / resource Sampling did not fully characterize diets of five less common species.
Observation Common Bombus species differed in feeding niches.
Observation Five of eight Bombus species most strongly preferred a non-native plant.
