How on earth have we let this thread languish...
Found this pic on a science forum...
Caleana major (known as the Large Flying Duck Orchid) is found in Australia. Its main pollinator is the sawfly, though why the fly is attracted to the duck-shaped bloom is unknown. There is a sensitive patch on the flower, that when stimulated by the presence of a fly allows the labellum (the portion that resembles a duck’s head) to fold down, pinning the insect inside. This not only allows the orchid to collect the pollen already on the fly, but it is able to coat the sawfly its own pollen to be spread elsewhere.
