The butterfly is common in montane forests at low to moderate elevations (Alt. 10 - 1300m). Both sexes visit flowers. They often fly out from bushes along the trail and rest on the underside of leaves with their wings spread.
Maruyama (1991:19) examined the male genitalia of the type specimen in the MFNB and strongly suggested that it seemed to be Tagiades menaka. Subsequently, some authors followed his suggestion and treated it as Tagiades vajuna instead of Tagiades litigiosa. However, the markings of the type specimen are clearly different from that of menaka. I have therefore reverted to the previous classification.
