Notes

The Fringed Heath Blue is one of Australia’s smallest and most inconspicuous butterflies. The upperside is uniformly brown, whereas the underside shows a complex pattern of black, brown and white markings and patches. A few similar species can be found in montane areas of NSW, ACT, VIC and TAS. However, the Fringed Heath Blue can easily be identified by the two v-shaped black marks on the underside of the hind wing.

The Fringed Heath Blue can be found throughout the temperate regions of Australia, where it is generally common in heathland and woodland from the coast up to about 1500 m in the mountains. The populations of WA and TAS form two separate subspecies, occidens and insulana, respectively, although the differences between these and the nominate subspecies are minor, with the underside markings of Neolucia agricola subsp. occidens often being less distinct.
