bumblebees

The calypso orchid is one of the most eye‑catching little flowers you'll see on forest floors across the Northern United States, Canada, and Europe. It's an early bloomer that appears in springtime each year, showing off deep purple petals and a yellow fringe on its dainty white lower lip.

Scientists think that bumblebees can speed up flowering in plants. They go the idea when doing a different experiment and noticing bumblebees using their mouths to pinch the leaves of plants that hadn't flowered yet.
