There is no question. The bee orchid is as bee-like as it is possible to be without being a bee. And that is a good thing, because bee orchids are heavily reliant on bees for pollination. A bee orchid needs to lure a bee and ensure that the bee leaves with at least one sac of pollen stuck to it, in order to achieve (the always desirable) outcrossing.
Male bees are attracted to bee orchids by both visual and olfactory cues. The flower parts resemble a female bee, and the orchid secretes species-specific floral fragrances. The orchids offer no obvious rewards, such as pollen or nectar, but researchers have discovered that the bees collect the fragrances and use them in their courtship. The bees mop them up using tiny brushes on the endmost segments of their front legs.
