Bay Skipper (Euphyes Bayensis)
This skipper is amost indistinguishable from the dion skipper (Euphyes dion).  The males have narrower stigma and are more orange dorsally.  The biggest difference is habitat.  The bay skipper seems to inhabit salt marshes southwestern Louisiana while the dion skipper doesen't.  Not all authorities belive that these are two separate species.
