Banteay Srey Butterfly Centre (BBC)

This guide to the Banteay Srey Butterfly Centre near Siem Reap follows every free-flying butterfly overhead back to a caterpillar raised by a nearby farming family, trained to breed native species instead of catching them wild. It traces the centre back to 2009 and two British enthusiasts, Ben Hayes and Mike Baltzer, who had already tried the idea on Zanzibar before building the largest enclosed butterfly centre in Southeast Asia here. Look near the entrance, where chrysalises still hang waiting on the farmers who raised them.
