Black and white

Haven't identified this butterfly yet, seen in the Garden Gallery at the Calgary Zoo (Enmax Conservatory). I liked the startling black and white against the pale green leaves. A bit later: thanks to Art (LeapFrog!) for the ID, Common Sergeant Butterfly (Athyma Perius). Much appreciated.

"Distribution: throughout the Himalayas; the hills of Central, Eastern and Western India : Southern India.; Burma; Tenasserim; extending to Siam and the Malay Peninsula." en.wikipedia.org/wiki/Athyma_perius

The snow has gone, the rain has gone, the very strong winds have gone - and (yes, Joyce), the SUN is shining!! More snow in the forecast for next week, though, unless it changes.
