I think the uva/uvb lights would be more important if you were trying to keep plants growing, as a food source. I looked up info from a butterfly conservatory. They didn't have any info on what lighting they use, but they did say that they keep the conservatory at 85 degrees and 75% humidity. They have automatic misters set up to send out a fine mist hourly, so there is surface moisture available throughout the day. Sounds like a lot of work to me - I'll just enjoy what's outside!
