The favoured food plant of the Caper White Butterfly (sub-species Belenois java teutonia) belong to the native caper plants genus Capparis. In Central Australia the Caper White can often be found fluttering around the Wild Passionfruit (Capparis spinosa var. nummularia).
Seen feeding on the nectar from the flowers of the caper bush, the Caper White Butterfly also lay their eggs on the caper bush for the next generation of caterpillars to butterflies.

When the eggs hatch, the caterpillars eat and grow, going through a number of instar stages, as they grow. They shed their skin (moult) between each instar stage.
During these stages, if there is a lot of caterpillars, they will often strip the shrub bare of leaves. Usually the native caper bush will survive this process.

The caterpillar of the Caper White Butterfly eat only plants that are in the caper family (Capparis spp). In these images from Central Australia, you can see that the caterpillars have just about stripped the Wild Passionfruit (Capparis spinosa var. nummularia) of its leaves. In most cases, the plant will recover.
