I like watching the bees in the garden. They have their different methods of collecting nectar and pollen from different plants. It appears they collect nectar from some, pollen from others and nectar and pollen from still others. The collection can be extremely rapid visit or a more relaxed endeavour.
This bee had an extremely thorough approach to her grooming of a single echinacea flower and I photographed her engrossed in her enterprise for eight minutes.
