Can anyone help me identify this butterfly? I shot the photo at an indoor butterfly garden, and it doesn't seem to be included in the list of "popular" species there. The most I can figure out is that it seems to be part of the Heliconius genus of butterflies (http://en.wikipedia.org/wiki/Heliconius). Any help with better identification would be greatly appreciated. ( photo / image / picture from Will Montague's Garden )
