About the Mottled Emigrant
Catopsilia pyranthe, the mottled emigrant, is a medium-sized butterfly of the family Pieridae found in south Asia, southeast Asia, and parts of Australia. The upperside is chalky white, slightly tinted in some specimens with green. The forewing is with or without a discocellular black spot, that varies in size; costa and termen sometimes without a black margin; occasionally the costa has its apical third narrowly black, broadened slightly at the apex with black spots between the anterior veins; or again, the costa may be narrowly black, the apex very broadly so, and this colour continued down the termen but narrowed posteriorly. The hindwing is sometimes immaculate, but generally with narrow terminal black spots at the apices of the veins, these often reduced to mere dots, or again so broadened as to coalesce into a narrow terminal black margin.
The underside's ground colour is similar, suffused on the anterior half of the forewing and over the whole surface of the hindwing with a greenish tint that varies to an ochraceous yellow, and, except in the very palest specimens, is evenly irrorated (sprinkled) over the greenish or ochraceous-tinted areas with transverse...
