Not much is known about this species which can be found in coastal rainforest and monsoon forest across eastern and north-eastern QLD. Males can be easily identified by their characteristic, triangular wing shape, whereas females look very similar to other species of Blue, in particular species of the genus Nacaduba and Prosotas, including the Large Purple Line Blue (Nacaduba berenice), the Long-tailed Line Blue (Prosotas nora), and the Short-tailed Line Blue (Prosotas felderi).
