Question

What is pseudocopulation mechanism?

Answer 1

Pseudocopulation describes behaviors similar to copulation that serve a reproductive function for one or both participants but do not involve actual sexual union between the individuals. It is most generally applied to a pollinator attempting to copulate with a flower. Some flowers mimic a potential female mate visually, but the key stimuli are often chemical and tactile.
Ophrys, a genus of orchid exhibits this form of pollination mechanism.
