Penang Butterfly Farm is the first tropical butterfly farm ever set up in the tropical world, with an average flying population of 4000 Malaysian butterflies of 120 different species. I went there last Saturday and came back with some close-up photos on butterflies. Entrance fee is at RM20 per adult (50% discount for Malaysian). It's a great place to train up your close-up and macro shooting skills.
