The butterfly is uncommon in montane forests at low elevations (Alt. 50 - 150m).
This species is very similar to Tajuria dominus dominus H.H. Druce, 1895. As identification based on markings is difficult, examination of the genitalia is essential.
Kimura et al. (2014) recorded Tajuria dominus from Phuket, P. Thailand. It is highly probable that it belongs to Tajuria culta, but this cannot be confirmed as only a female specimen is available. Further taxonomic and distributional studies are needed.
