Bronze Copper & American copper

Male Bronze Copper. The males and females of this species look quite different. Males are bright purple and orange.

Female Bronze Copper. The dorsal wing pattern is similar to that of the American Copper, but Bronze Coppers are larger butterflies and prefer wetter habitat.

Some researchers believe that the American Copper might have been introduced from Europe. (This theory is disputed, and others believe that these butterflies are native to both continents.) Our "American" Coppers are called Small Coppers in Europe. 

This is an American Copper butterfly. This species is smaller than the Bronze Copper, and they are found in drier habitats (such as fields and meadows). Notice that there is a distinctive thin red line on the hindwing. American Coppers are quite uncommon in our area; the only place I have encountered them to date is Huffman Prairie. I find American Coppers at Huffman Prairie in small numbers from late June through early August.
