Thanks Jim, Jeff, Chris and Tom! FYI.. I added one more I missed..
Jeff - The Conservatory at the gardens is having a butterfly exhibit until Apr 4th. You need to order tickets ahead of time from their web site (
The Fort Worth Botanic Garden - Sanctuary for the Senses) to pick an entry slot. We went at the 3:30pm slot and they were pretty active at that time. Also, be sure to pick a sunny day to be able to get more light in the Conservatory.. The last entry time is at 4:00 and they close at 5 (least the day we went). By that time the butteflies were starting to bed down for the night it seemed anyway.
