Very little is known about the role nocturnal insects, such as moths, play in flower pollination because it is difficult to monitor insects at night. To address this problem, a team of scientists used time-lapse cameras to record pollinator visits to red clover all day and night. The recordings showed that while most pollinator visits were by bumblebees, one-third of visits were by moths. Additionally, flowers that were visited by both moths and bees produced more seeds than flowers that were only visited by bees.
