My husband has a dream to keep butterflies but we don't know if it is possible. We have a planted garden area covered by polycarbonate and surrounded by glass. The area is approx 4m x 8m x 3m it contains a waterfall and a rockery garden. Within this area he would really love to keep butterflies as they do in the butterfly houses created for tourists.Does anyone know if this would be possible and where we could find more information on doing so?Jill
