The butterflies that fly at the park, travel here as pupa or chrysalis, as at this is stage of development it is easier to transport them during this life cycle. They come from as far away as the Philippines, Malaysia, Costa Rica, Belize and Kenya where they are bred in captivity, not captured in the wild. Once in the laboratory and after being inspected, they are placed in hatching cages under controlled environmental conditions. This is when you, as a visitor, can experience the butterflies being born in front of your eyes. Once released in the garden they are fed with artificial nectar which is prepared daily in the Lab.
