I go every year to the University of Florida to take their "short course" for a few days - to keep up the education hours necessary for the Master Gardener Program. This was taken on a field trip last year at the Florida Museum of Natural History in Gainesville, at the the Butterfly Rainforest Exhibit.
Amazing place; they get chrysalis' from all over the world; and then they're put in the garden. No host plants though for them to lay eggs and reproduce - just nectar for them, until they die. Lots of doors to go through (wind tunnels). They can't take the risk of an escape and causing problems with Florida's flora or perhaps the agricultural industry.
