Yes, the same is true for hummingbirds, as they seemed to have prefered lilies for nectar. (as did other nectar eating fauna too). Although, I don't have nearly as many Lilium varieties as you, Tracey. I grow a huge diversity of flora, and more often than not, the hummingbirds would just pass by lilies in favor of various Impatiens spp., Digitalis, Centranthus, Campanula, Aquilegia, etc. Insects seem to like my lilies' nectar better than hummingbirds. in particular, it has been a lot of fun watching bees disappear into Impatiens glandulifera and I. balfourii flowers, then backing out. Actually, it has been even more fun watching visitors watch the bees in wonderment.
