I've seen bumblebees and other large bees bite holes in flowers with long floral tubes in Salvia sclarea and Agastache aurantiaca, but strangely not in Crocosmia 'Lucifer'. All are visited by hummingbirds in my garden. It's possible that the latter produces no scent detectable to bees, or any other "bee attractant", being primarily a bird pollinated genus (Crocosmia in Africa are pollinated by sunbirds), while the Salvias and Agastaches have nectar guides and easily detectable scents.
