Bassarona durga, the blue duke, [1] is a species of nymphalid butterfly found in the Himalayas.
Euthalia durga resembles Euthalia duda , but is much rarer; on the forewing the white median band is broader, the subapical spots smaller, on the hindwing the median area steeper and distally dentate. Under surface chiefly blue instead of yellowish-green, the distal portion of both wings nearly grey-black. [2]
It is found in Sikkim, Abor Hills and Nagaland. [1] In June 2022, it was declared as the State Butterfly of Sikkim. [3]
