Lemon Emigrant Butterfly (Male form alcmeone)

Catopsilia pomona (Fabricius, 1775), of family Pieridae, subfamily Coliadinae, called the Lemon Emigrant or Common Emigrant, is a medium-sized pierid butterfly found in Asia and parts of Australia. The species gets its name from its habit of migration.

The Lemon Emigrant is represented by at least 6 different 'forms' in the region - the 'crocale' forms with the antennae black above and the 'pomona' forms with the antennae red above. Some early authors considered them as two distinct species Catopsilia crocale and Catopsilia pomona.

Catopsilia pomona pomona (Fabricius, 1775) is the recorded ssp in the Philippines. This spotting is that of a male form alcmeone (Cramer 1777).
This male has antennae black above, margined with narrow black markings on the forewings above (apex), and unmarked on the undersides without silvery spots at the cell-ends. Upperside creamy white wings with base of wings lemon-yellow.
