Vitamins in native tree pollens are essential to support fitness of wild-caught Bombus spp. queens, with positive carry-over effects

To implement adequate nutritional landscapes to bumble bees and inform conservation efforts, we need a better understanding of how different pollen sources impact bumble reproductive performances and phenology. We assessed the impact of multiple native pollen on bees reproductive success by feeding 40 wild-caught Bombus impatiens and B. griseocollis queens with either commercially wildflower…
