- The Mediterranean orchid ophrys employs sexual deceit.
One petal of its flower bears an uncanny resemblance to female of the bee in size, colour and markings.

In this process pollens are dusted from the flower.
- Same bee when pseudocopulates with another flower transfers pollens therefore pollination takes place.
