The butterfly is locally common in montane forests at low to moderate elevations (Alt.30 - 700m).
This species is quite similar to Arhopala major. The only difference between two species is a presence or absence of a small white spot on cilia in space 1a on the UnH. Arhopala norda has this, while Arhopala major lacks it. However, this area is easily damaged and the cilia can also easily drop off; therefore, examination of male genitalia is recommended for reliable identification. Previous records are less reliable, so only records with confirmed genitalia are used.
