Bumblebees bite plants to make them flower early -- Science:

Bumblebees aren't merely bumbling around our gardens. They're actively assessing the plants, determining which flowers have the most nectar and pollen, and leaving behind scent marks that tell them which blooms they've already visited.

Now, a new study reveals that bumblebees force plants to flower by making tiny incisions in their leaves — a discovery that has stunned bee scientists.
