How do bats help pollinate tropical plants?

Bats play a vital role in the pollination of over 500 species of tropical plants, which have evolved specific traits to attract these nocturnal mammals. These plants, known as chiropterophilous or "bat-loving," typically produce large, sturdy, white flowers that are easily visible at night and often emit a musky or fermented odor to guide bats to them.12

To facilitate pollination, these flowers are often shaped like vases or have brushy structures that load a bat's face and whiskers with pollen as it feeds. Some plants even exhibit specialized positioning, such as growing on tree trunks or dangling beneath the crown, to make it easier for bats to approach.12

In return, the plants provide nectar and protein-rich pollen, which are essential for the health of nectar-eating bats. These bats have adapted with long, extensible tongues featuring fleshy bristles or papillae to efficiently extract these resources. As they travel between flowers—sometimes along specific "nectar corridors"—they transfer pollen, ensuring the reproductive success of these tropical plant species.132
