White-checkered Skipper (Pyrgus albescens)
In Louisiana white-checkered skippers are found mainly along the gulf coast, but do occur in all of Louisiana.  They look exactly like common-checkered skippers and can be distinguished only by examining the genitalia.  This photo was taken in Hidalgo County, Texas which is out of the range of common-checkered skippers.  So we know that this is likely a correct identification.
