Mexican Longwing / Heliconius hortense

Taken in the ENMAX Conservatory at the Calgary Zoo on 14 October 2014. I’m not completely sure of this butterfly’s ID, but I think it might be a Doris butterfly (Heliconius doris). If anyone can confirm or correct this, it would be greatly appreciated.

Many thanks for the correct ID, Bob (Decker) - Heliconius hortense. Much appreciated!

Whenever one goes into the Butterfly room, it’s very warm and humid. This is bad enough in the summer, but now that we need sweaters and jackets, it feels unbearably hot in there. When I was there briefly with my daughter the other day, it took 20-30 minutes for my camera lens to defog, and by then, it was just about time to leave, ha.
