I just realized that I have not seen one, not ONE butterfly in my yard this year! I looked at my notes and pictures from previous years. Last year I had monarch caterpillers on my milkweed June 6th. That same day I took pictures of a butterfly and at sphinx moth on my salvia. This is normal! I usually have lots of both of them!
I know last year was warm and things were early, and this year is cold and things are later. But NO butterfly's??? It seems really odd to me.
