Heliconius sara
(I.D. courtesy of Danny Burk)

The materials supplied by the Butterfly House showed a number of different species of Helioconius, but many of the ones I photographed didn't match any of these. Thanks to Danny Burk for identifying the species. Canon 100-400 at 400 mm, 20 mm extension, ISO 400, f/16, 1/200 second (manual mode), 550EX Flash EV +2/3, monopod with Arca-Swiss ballhead and Wimberley Sidekick.
