Beschreibung:
Solitary bees (Halictus sp.) were found to be the effective pollinators of Cephalanthera longifolia. In the same foraging flight the bees also visit flowers of Cistus salviifolius which has a similar colour pattern. Cephalanthera offers no reward to its pollinators, but orange papillae on its labellum successfully imitate pollen of Cistus. As Cephalanthera also attracts pollinators in the absence of Cistus, this is regarded as "facultative floral mimicry".
