Explain what is meant by the term, "promiscuous" pollinator. what characteristics evolved in plants to improve pollination efficiency by a "promiscuous" pollinator?

Explanation:

If we look at the term "Promiscuous" pollinator, it is meant by when the long-nosed fly does not stick to one plant species, but go to any other flower species. The members of the guild have evolved to deposit their pollen on differing parts of the nectar-seeking fly, each part characteristic of the plant species. Characteristics evolved in plants to improve pollination efficiency by a “promiscuous” pollinator is when the even though the female reproductive structure prevent them from getting the “right” pollen, the stigmata of plants in the guild of mega nosed fly do not clog because among those plants. The long-nosed flies obviously get privileged access to pools of nectar.The plants pollinated by long-nosed flies benefit from a near-exclusive pollen courier service.
