Delaware is a lot more orange and is generally brighter. You can see the hint of the HW chevron marking in this specimen. I'd say that, combined with the dull yellow-brown color, makes this a fresh Sachem. Sex is unsure without a dorsal shot.

I looked through guides and many excellent internet images and agree that the skipper is probably not a Delaware Skipper which seem to have a very clear hindwing viewed below while this skipper has as you point out, some markings. I also looked at a lot a Sachem Skippers that are on the internet and also some descriptive material and find that male Sachem's markings on the hindwing are different than the female in being much less distinct -the wing color also being more yellow and less brown. So male Sachem seem reasonable the primary contraindication being the extreme weakness of the markings. If weakness of markings are an indication of freshness or a normal variation then Sachem seems ok. Certainly Sachem are extremely common in the area -September and even October. I know a dorsal shot of the top forewing would show the stigma were it a male and so make the sex certain.

Why was this moved back to ID Request? In general, our experts are more likely to examine images on the guide pages of their specialty area rather than here...

Because I thought it might get more attention. Lingering on the Skipper page was producing no results. Of course Skippers except strongly marked ones are often an identification problem. With no identification related responses I considered other possiblities and edit my remarks adding those. I did get a response -yours- but not helpful in identifiying the species. I'll return it to the family page shortly, after probably hearing nothing more. Thanks for the advice.

as you imply, is a virtue on this site. :) I've had several of my images identified a year or more after I submitted them. Although our experts sometimes provide quick ID's, instant gratification is not the usual scenario with skippers...

I decided that rather than a Sachem, it may be a Europeon Skipper. The Sachem especially the female have cheveron markings on the hind wings. They are, however, common in September in Maryland.
The extreme hairiness that can be seen on this skipper's body is unusual; the hairiness can be seen in the field guides and various internet images of European Skippers but hairiness is not discussed in identification texts. I'm leaving this on ID request; hope to get some further opinions. I've considered Crossline Skipper but these have spots the underside forewing. One big difficulty with the European Skipper is that from the J. Glassberg's " Birding through Binoculars" they would not be expected in Maryland in September and Maryland seems the furthest south for it distribution.
