Bumblebees landing on asters in the autumn sun gathered nectar from flower to flower.
Close-up footage shows bumblebees working over asters with purple petals and yellow centres, pausing for a few seconds on each flower to gather nectar before moving on to the next.
Filmed on a sunny day, the vivid blooms stand out against a backdrop of green leaves, and grains of pollen clinging to the bees’ bodies can be made out in close-up.
Gardeners note that autumn-flowering plants are an important source of food for bees before winter.
