I recently visited the Natural History Museum in Washington DC. On the second floor there was a butterfly house on permanent display. It cost 6.50. Very nice!!

Very hot & humid in there!
You could stay in there as long as you want. This message was edited May 25, 2010 5:34 PM
Not sure of their names.
This was my favorite part of the museum! I can't wait to go back!
