I photographed this Short-lined Chocolate, Argyrostrotis anilis, on Sunday, April 26 at Forks of the River Wildlife Management Area in Knox County: http://www.flickr.com/photos/avian_pursuits/3479278825/ Don't know anything about how common/rare they are, but it is not recorded for Tennessee on BAMONA or Bugguide.net (I've posted it at bugguide now) David Trently Avian Pursuits Nature Tours ...come see the real world!
