Female - Simple identification by 2 large white spots on upperside wing in the subapical area. Male will have 3 spots. Very fast strong fliers.

These butterflies are attracted to fermenting juices of rotting fruit and sap. In our yard we have some larval foods as well as rotting fruit. This butterfly was flying around both the brachychiton and the fruit trees.
