<p>Scalloped Grass-yellow, <i>Eurema alitha</i>. Emu Park, Queensland, Australia, April 2015.

This closely resembles a Large Grass-yellow, <i>Eurema hecabe</i>. However, in that species the upperside of the hindwing has a narrow black stripe on the outer edge of the wing. In my photo there is a shadow of a much broader stripe on the outer edge of the hindwing.
