Bats Follow Ultraviolet Light to Nectar, Study Suggests

Halloween decorators take note: Reflected ultraviolet light lures bats to succulent treats. Fortunately, these bats live in the rain forests of Central and South America.

According to a team of German and Guatemalan researchers, rain forest flowers that reflect ultraviolet light may help guide the color-blind bat Glossophaga soricina to their nectar like a harbor beacon guides a ship to shore at night.
