2005 Highlights: The Saline River in Arkansas likely contains the largest known population of winged mapleleaf; 27 were found in a search of 28 quadrats in summer 2005. In early November 2005, 7 gravid females were collected (in 15 minutes!) and taken to Chris Barnhart at Missouri State to confirm the hosts for the southern populations.
