This Grass Skipper sp. was
at the Santa Ana NWR, Hidalgo County, Texas on May 01, 2004; it
reminded me of a Delaware Skipper Anatrytone logan, but
was a bit yellower (rather than more orangy) and had strongly
visible pale veins; I recall there is at least one skipper in
northern Mexico that looks a bit like this ( maybe A. mazai?),
but I don't have any references. This is the only photo I obtained:
