Caleana major (IMAGE) La Trobe University Caption As is the case for many orchids, the Dragon Orchid (Caladenia barbarossa) is pollinated by just a single species of insect. Here, pollination occurs via a male thynnine wasp, which is sexually attracted to the flower through mimicry of the wasp's sex pheromones. In this photo the male wasp removes and deposits pollen in the process of attempting to copulate with the flower Credit Dr Ryan Phillips, La Trobe University Usage Restrictions Please seek permission.
