Which kind of population interaction is found between organism showing psuedocopulation?

The Mediterranean orchid Ophrys employs ‘sexual deceit’ to get pollination done by a species of bee. Co-evolution operates in Ophrys and a bee species. One petal of its flower bears an uncanny resemblance to the female of the bee in size, colour and markings. The male bee is attracted to what it perceives as a female, ‘pseudocopulates’ with the flower, and during that process is dusted with pollen from the flower. If the female bee’s colour patterns change even slightly for any reason during evolution, pollination success will be reduced unless the orchid flower co-evolves to maintain the resemblance of its petal to the female bee.
