<p>The Common Emigrant or Lemon Emigrant (<i><a href="https://en.wikipedia.org/wiki/Catopsilia_pomona" class="extiw" title="w:Catopsilia pomona">Catopsilia pomona</a></i>) is a medium sized <a href="https://en.wikipedia.org/wiki/Pieridae" class="extiw" title="w:Pieridae">pierid</a> butterfly found in <a href="https://en.wikipedia.org/wiki/Asia" class="extiw" title="w:Asia">Asia</a> and parts of <a href="https://en.wikipedia.org/wiki/Australia" class="extiw" title="w:Australia">Australia</a>. The species gets its name from its habit of migration. 
</p><p>This is a very variable species with many named forms. There are two male forms, f. alcmeone and f. hilaria, and five female forms, f. pomona, f. crocale, f, jugurtha, f. catilla and f. nivescens. Of theses, f. alcmeone is the commonest male form, and f. crocale is the commonest female form for most of the year. However, during the months of May- July, f. jugurtha appears to be more common. The remaining forms are present for most of the year, but in lesser quantities.
