That’s only the first step, because these adult butterflies will have other needs too. They will need protection from wind, water, and a then...there also needs to be a food source for the caterpillars. Sometimes the nectar producing plants will also provide food for caterpillars, but not always.
For their water needs, provide a shallow bird bath, saucer or even puddles. Butterflies like sunny, warm spots which are protected from high winds, so locate your garden in a sunny area which has a tree line or structure which protects it from the prevailing winds.Avoid using any pesticides or other chemicals in the area. This may kill the butterflies or the caterpillars.
