Pollinators exert natural selection on the
flowers they visit, affecting how flowers evolve over time. Different groups of
pollinators, like nocturnal moths or diurnal bees, often have distinct
preferences in choosing which flowers to visit. The colours, shapes, sizes, and
scents of many flowers today reflect interactions with specific pollinators
over evolutionary time, but do not necessarily predict which types of pollinators
are important to particular plants today. To determine which flower visitors
are effective pollinators, it is important to document the full range of
visitors to flowers and determine the relative pollination effectiveness of
each group.
