Double-spotted Line Blue (Nacaduba biocellata ssp. armillata)
The Double-spotted Line Blue is distributed from Indonesia to Australia as well as Melanesia, where the ssp. armillata (Butler) occurs.
The species is known in Fiji from only two individuals of the Melanesian subspecies, that were collected at Lautoka, a city in the northwest of Viti Levu, and which possibly were vagrants.
The caterpillars feed on the flowers, buds, and shoots of several Acacia species.
