The Large Green-banded Blue can be found locally along the edges of tropical rainforest in north-eastern QLD. There are a few similar species, in particular the Small Green-banded Blue (Psychonotis caelius) and the Green-banded Line Blue (Nacaduba cyanea). The Large Green-banded Blue can be easily distinguished from these by the light-blue, iridescent band on the underside, which extends along the costa, apex, and termen of the fore wing, and the lack of a tail on the hind wing.
