This species also photographed on 10 and 19 July 2000, on 29 June 2001, and on 3, 22 and 26 July 2001.  This species is quite variable, with several named forms, including "enucleata" as noted above.  Any guidance as to identifying specific forms among the first three specimens pictured would be appreciated.
