The joy of colour

An old photo from the archives, grabbed last night after a dreary, snowy day. A birding outing was postponed till another day, but I'm going on a different one today, so hopefully the forecast for sunshine will turn out to be accurate. No sign of the sun yet.

Photo taken in the ENMAX Conservatory at the Calgary Zoo, on 25 September 2012. I believe this butterfly is a Sara / Heliconius sara. If someone is able to either confirm or correct the ID, that would be much appreciated - thanks!
