Various tropical and subtropical legumes. Documented hostplants occurring interstate and which can also be found growing in South Australia include **Cassia spp, **Caesalpinia spp, **Senna spp (Caesalpiniaceae); some Acacia spp incl. **A. baileyana (Cootamundra wattle), *Paraserianthes (Albizia) sp (Mimosaceae); *Aeschynomene sp (Budda pea), Indigofera spp (indigo's), Sesbania cannabina (yellow pea-bush) (Fabaceae). There has been a recent (2009) unconfirmed report of females in north Queensland laying eggs on *Medicago laciniata (Cut-leaf Medic) (Fabaceae), that have coiled bindii-like seed pods. Females have also been seen to utilise *Trifolium repens (White Clover) (Fabaceae) in Queensland, but in nearly all cases the larvae did not develop through to the adult stage, but if they did then they were 'stunted'. In South Australia its hostplants have not been recorded in the wild, but Sesbania cannabina is likely to be the principal candidate as adults have been seen lingering about these plants in the Far Northeast.

The butterfly is seen all year round in the tropical north of Australia. It flies south during the southern warmer months. In South Australia, it has been documented during April, early September, mid November and mid December, but as there have been very few butterfly surveys in the Far North of the state, these flight periods will certainly be extended.

Normally a butterfly of the humid tropics and subtropics. It is a strong vagrant, moving south into subtropical latitude areas during the warmer months after monsoonal rains. The South Australian records are from Port Lincoln, the south side of Lake Eyre and from the extreme Far Northeast area. In the latter area they are usually seen flying near a hostplant Sesbania cannabina that grows along the banks of the ephemeral creeks and lakes after floods, or within their flood plains. Small semi-resident populations of the butterfly are likely to occur in this area during favourable seasons. Breeding stocks are replenished from interstate northern tropical areas after good monsoon rains, with the butterflies following the major creek-lines down into South Australia. These breeding populations die out during the winter months, as their early stages cannot tolerate the frosty nights. The population adults then die out or reverse migrate to northern, frost-free areas. A poor monsoon season in the inland areas of Queensland and Northern Territory will not produce a migration into South Australia. The butterfly is not biologically suited to the subtropical and temperate conditions of South Australia.

The likely principle hostplant Sesbania cannabina occurs sporadically in the extreme Far North of the state, particularly along the ephemeral creeks of the Lake Eyre Basin and more particularly the flood plain areas of the Cooper and Diamantina-Warburton Creeks.

A vagrant. Locally resident after periods of good inland rains. Common in the north of Australia.
