Pollination of Orchids Through Pseudocopulation
Abstract
WITHIN comparatively recent years, biologists have been made aware of a peculiar relationship between certain orchids and the hymenopterous insects which pollinate them. A wholly unexpected trend in biological behavior has been revealed and it has been proved that the motives leading to pollination are much more complex than formerly had been supposed. It is now known that certain insects are attracted by orchids for a purpose wholly apart from the search for food and that there are aspects of pollination presenting new and practically unexplored fields for research.
