Red-spotted Purple (Limenitis arthemis astyanax and L. arthemis arizonensis)
These two subspecies of Limentis arthemis lack the prominent white bands on both wings. The range of these two subspecies is shown because these look so different from the white-banded form. The fact that both forms interbreed over a broad zone and produce fertile offspring is why they are treated under the single species (see page for Limentis arthemis).
