Bumble bees generally visit flowers exhibiting the bee pollination syndrome. Bumble bees will also tend to visit the same patches of flowers every day, as long as they continue to find nectar and pollen, a habit known as pollinator or flower constancy. While foraging, bumblebees can reach ground speeds of up to 30+ miles per hour.
Adults grass skippers typically visit flowers and hold their wings together while feeding. They hold their wings partially open while resting, with the front wings and hind wings held at different angles. They are usually orange, rust, or brown in color and have pointed forewings. Many species have dark markings or black stigmas on their forewings.
I was pleasantly surpised to capture these two sharing this bull thistle in my back yard in Rockaway, NJ USA. I took this with my Nikon D3100 and the Nikon 85mm macro lens.
