The garden didn't have too many butterflies in my visit and sadly enough there isn't a species list of the butterflies in it so I'll just list off the few I could ID:
Glasswing butterfly (Greta oto), Transandean cattleheart (Parides iphidamas), Owl butterfly (Caligo sp.), Julia butterfly (Dryas iulia) and Longwing (Heliconius sp.)
