Yesterday my zinnias were covered with American painted lady butterflies, the most I've ever seen at one time. I'm not sure if they were migrating south and just stopped here on their way or if they had just recently emerged. They were very calm and didn't fly away when I got close, in fact I was able to get the camera within inches of them. What a wonderful treat to be this close to so many butterflies. I will most definitely plant masses of zinnias again next summer.
