The air is cool and crisp, and Fall is definitely here. The trees are beginning to turn and my gardens are looking a little tired. I hate to see summer end. These are my zinnias and the purple flowers are called black and blue salvia. Here in Milwaukee, we have a large population of sphinx moths, however most people are calling them hummingbird moths because they hover the way hummingbirds do and enjoy many of the same flowers. They particularly like my black and blue salvia. Apparently they are common in our area, but no one remembers ever seeing them before. They are really fun to watch, and certainly a challenge to photograph.
