Which is a major pollinator of agave and saguaro plants?

The major pollinator of agave and saguaro plants is the bat, specifically the lesser long-nosed bat and the Mexican long-tongued bat. These bats are attracted to the flowers of these plants, which bloom at night, and they play a crucial role in their reproduction by transferring pollen as they feed on nectar. Other pollinators, such as bees and birds, also contribute, but bats are particularly vital for agave and saguaro species.
