The flowers of certain plants have evolved over the years and their pollination has adapted specifically for these bats. This reciprocal species evolution is called co-evolution. The big bat flowers open at night and can be easily found by the animals as the sweet nectar oozes out of the plants.
Flowers are difficult to detect by echolocation. The bats search for their food by using their attraction to ultraviolet light. These flowers glow at night so they can be found by the colour-blind bats.
