In a world of bokeh

Photographed in the ENMAX Conservatory at the Calgary Zoo on April 20th.

It's raining this morning and I don't know if the roofers will be working in the rain. It's also Saturday and I have no idea if they work on the weekends. I had to be up really early this morning and must finish getting ready in case the guys do appear and I have to suddenly move my car from my parking spot and kill 12 hours in the rain (as the city still hasn't sent me a residential parking permit).

Thanks, Art, it looks like you found the right ID - Tiger-striped Longwing / Heliconius ismenius clarescens. When I had looked on the main butterfly site that I use, I couldn't find a butterfly like this one. There are several others that have the same colouring and a fairly similar pattern.
