The butterfly is not rare in montane forests at low to moderate elevations (Alt. 10 - 1300m) and often comes to rotten fruits that has fallen to the ground.
I have observed Euthalia dunya ♂ courting Euthalia patala ♀. The dunya ♂ persistently courted the patala ♀ for about five minutes before the patala finally flew away. The key to interspecific recognition in dunya could be the ground colour of the underside.
