Jeremy Tatum writes:   I mentioned on July 18 that I had learned from the Sussex, England, butterfly site that there is a difference in the shapes of the antennae of the Woodland and Essex Skippers.  This can be seen in photographs on this site for July 28 (Woodland) and July 11 (Essex).  The tip of the antenna of the Woodland Skipper is hooked at the end.  That of the Essex Skipper is blunt.
