New Scientist report:- “Hungry bumblebees can coax plants into flowering and making pollen up to a month earlier than usual by punching holes in their leaves.
Bees normally come out of hibernation in early spring to feast on the pollen of newly blooming flowers. However, they sometimes emerge too early and find that plants are still flowerless and devoid of pollen, which means the bees starve.
Fortunately, bumblebees have a trick up their sleeves for when this happens. Consuelo De Moraes at ETH Zurich in Switzerland and her colleagues discovered that worker bumblebees can make plants flower earlier than normal by using their mouthparts to pierce small holes in leaves.”
BBC Report:- “Dr Walton from University College London and colleagues monitored moth activity around ponds in agricultural areas of Norfolk.
They found that 45% of the moths they tested were transporting pollen, which originated from 47 different plant species, including several that were rarely visited by bees, hoverflies and butterflies.
The scientists found that while bumblebees and honeybees are critically important, they tended to target the most prolific nectar and pollen sources. Not so with moths.
“From what we see from our work, moths tend to be generalists, meaning they’re not specifically visiting a narrow group of flowers,” said Dr Walton. … ”
