Orchid plants deceive their pollinator, which is a wasp, so as to carry out pollination. 

  • The petals of Ophrys have an uncanny resemblance with the female wasp.
  • The petals also produce pheromones similar to the female.
  • This lures the male wasp towards the plant.
  • The wasp ‘pseudo-copulates’ the plant.
  • In this process, the pollen grains of the orchid plant get stuck on the body of the pollinator (Wasp) and in the another cycle of pseudo-copulation these pollen grains reach the new orchid plants and get pollinated.
