According to new research published last month in PLOS ONE, moths are more efficient pollinators at night than day-flying pollinators such as bees. Phys.Org reports Studying 10 sites in the South East of England throughout July 2021, [researchers from the University of Sussex] found that 83% of insect visits to bramble flowers were made during the day. While the moths made fewer visits during the shorter summer nights, notching up only 15% of the visits, they were able to pollinate the flowers more quickly. As a result, the researchers concluded that moths are more efficient pollinators than day-flying insects such as bees, which are traditionally thought of as "hard-working." While day-flying insects have more time available to transfer pollen, moths were making an important contribution during the short hours of darkness.
Professor Fiona Mathews, Professor of Environmental Biology at the University of Sussex and co-author this latest research, says, "Bees are undoubtedly important, but our work has shown that moths pollinate flowers at a faster rate than day-flying insects. Sadly, many moths are in serious decline in Britain, affecting not just pollination but also food supplies for many other species ranging from bats to birds. Our work shows that simple steps, such as allowing patches of bramble to flower, can provide important food sources for moths, and we will be rewarded with a crop of blackberries. Everyone's a winner!"
