The North American version of Butterfly was retitled Dear Eloise / King Midas in Reverse, given a different full-color cover featuring a picture of the group, and released on Epic Records on 27 November 1967. The US and Canadian versions both included the single "King Midas in Reverse" and the UK Evolution track "Leave Me", while deleting the UK Butterfly songs "Pegasus", "Try It" and "Elevated Observations".
