American Copper butterfly

Hi, here is a small but very colorful butterfly usually seen by me on small flowers. The first is on White or Ladino Clover and the other is on Penngift Crown Vetch,  These small butterflies are sometimes difficult to even see, let alone ID properly.  Here are some pics of the American Copper for you to view. The first  butterfly pix has a large chunk taken out of it's wings, but able to fly well, Denis
