Yellow Zinnia flower and a butterfly. I don’t know the name of this butterfly in English, but we call it as “一文字セセリ(Ichimonji Seseri)” in Japan. I saw this butterfly around Zinnia flower many times in Japan and in America.
Below two other pictures are Zinnia and Eastern Tiger Swallowtail. I often see Eastern Tiger Swallowtails around Zinnia Flowers.
