So excited to get this video of a Carpenter Bee nectar robbing Penstemon digitalis 'Husker Red' - Beardtongue Cultivar. Nectar robbing is when a bee (usually Carpenter Bees but also ants, birds and moths) drills a hole in the corolla of the flower thus bypassing the reproductive organs of a flower to steal the nectar. Some say this leads to less seed production. Others say this increases seed production because bees that do go in the flower need to visit more flowers in order to get more nectar since the supply is diminished by the robber. Something to think about.
