Heliconius ismenius telchina on Egyptian Stars

I think I have the right IDs for this butterfly and the flower cluster (Isabella Tiger and Egyptian Stars, Pentas lanceolata), seen in the ENMAX Conservatory at the Calgary Zoo. Not as sharp as I would have liked, but thought it was still pretty. Fell into bed 2-3 hours earlier than usual last night, as I just couldn't keep my eyes open any longer. This is something I never normally do, which tells me I was way beyond "tired". Had hoped to have a much-needed long sleep, but I woke up early. I don't think sun is in our forecast for today (gloomy so far), so maybe I will get a few very urgent things (like food shopping) done instead of cruising a few of the gravel backroads with my camera, LOL.

Many thanks to DavidFingerhut.com for letting me know the definite ID, Eueides isabella!

Later note from bayucca - "Heliconius ismenius telchina, not Isabella. See notes for separating the very similar looking ones." Thanks for the detailed info!
