Clouded Skippers from May 2015

There was a post on TX-Butterflies today about Clouded versus Liris Skippers.  I've never seen a Liris skipper but I've seen hundred of Cloudeds.  Here's a few recent photos.  The costal striping above the white spots near the tip if the fore wing seems pretty consistent.  These are from Santa Ana NWR this May.

Here's one from the National Butterfly Center 5/26/15.

But here's one from last June at the NBC.

And one from last October at the NBC.

And one from 11/21/13 at NBC.

Looking at the Liris Skippers photos on BOA I don't see the costal striping on any of the images.  I might have more trouble separating Liris from Julia's Skipper.  Guess I'll keep looking.
