Tiger-striped Longwing / Heliconius ismenius telchinia

September is the month that the butterfly room at the Calgary Zoo winds down. Photographed this beautiful butterfly on September 12th - love it when they land on something where there is no cluttered background : ) Can't help but smile when I see their tiny, "soccer-ball" eyes. As always, I think I have the correct ID, but would really appreciate any confirmation or correction - thanks.

Many thanks again to bayucca for the correct ID, Tiger-striped Longwing / Heliconius ismenius telchinia! I appreciate your help so much! I know I will embarrass myself by making the same mistake again.
