Arhopala democritus or white-dot oakblue, is a species of butterfly belonging to the lycaenid family described by Johann Christian Fabricius in 1793.

[2] It is found in Southeast Asia (Burma, Thailand, Mergui, Indochina, Langkawi, Peninsular Malaya, Singapore, Sumatra and Borneo).

[3][4] Male above Morpho-blue, female likewise of a bright blue, though not reflecting so much, with a broad black marginal band of the forewing which begins thin before the centre of the costa, growing 5 mm broad behind the cell, and ending again thin at the anal angle.

The under surface is particularly characteristic, since on the dark chestnut-brown ground all the rings and bands are broken up into small commata and dots, so that the chains are hardly noticeable.
