Project: Pollination systems of angraecoid orchids - from Darwin to the present day

Since the famous prediction of Darwin, the spectacularly long nectar spurs of Madagascan Angraecum orchids have represented a classic example of floral adaptation to long-tongued hawkmoth pollination. Although specialisations for a specific group of pollinators can be viewed as a key innovation that has been responsible for the evolutionary success of a lineage, extreme specialisations in turn can be linked with loss of evolutionary potential, decreasing the ability of species to adapt to future environmental change. Here we report a surprising pollinator shift in the orchid genus Angraecum from hawkmoth to bird and raspy-cricket pollination (in the insect order Orthoptera). This evolutionary shift occurred after this group of orchids dispersed to a new insular habitat that harboured both different environmental conditions and groups of pollinators than were present in their native island, Madagascar. This specialised plant-pollinator interaction further represents the first clear case of orthopteran-mediated pollination in flowering plants.
