We have a colony of Xenicas that breed in a grassy clearing under power lines where native grasses predominate. There are also lots of scaly buttons (Leptorcynhos squamatos) from which they get nectar.
Of an evening they congregate in small groups sitting on tall grass stems.
You may see these beautiful little butterflies on the Dorrigo Plateau in Autumn if you walk part of the Syndicate Track on Killungoondie Plains starting at the end of Slingsbys Road.
