It appears that these are three juveniles and an adult female.
Coneflowers, native North American flowers, are fun to photograph. They present interesting colors and textures. Additionally they attract butterflies, bees and other pollinators. The butterflies did not cooperate for pictures, but a honey bee was was more interested in the flower than my camera.
Every summer and early fall, I try to take pictures of bees. While I have take many pictures of bees that had to be discarded, occasionally I get some pictures that work.
