The Caper White Butterfly originates from an African species and probably migrated to India, Indonesia and then to Australia where it is now seen as the species Belenois java teutonia.
The Caper White butterfly is found predomenantly west of the Great Dividing Range, but is a migratory butterfly and every spring they fly south.
They are an aptly named butterfly because they only lay their eggs on plants belonging to the caper family (Capparis spp). They can lay them in large numbers on one bush and the catapillars (lavae) can just about strip the plant of all foliage, but the plants do tend to recover. The Caper Tree – Caper Mitchelli is the only caper plant that occurs naturally in South Australia, but due to drought and the effects of grazing it is not reproducing satisfactorily in SA. The other main source of laval food found in South Australia is the Bush Caper – Caper Spinosa, which is a domesticated version of the caper plant, and is commonly found in vegetable gardens across South Australia.
