Just as for the animal groups mentioned above, living in earth, water and air, the farmer must also create on his farm precincts a home for a varied insect life. This is found in an equally varied plant world. There is no tree, no shrub, no grass or herb that does not serve as the nutritive foundation for the grubs, larvae or caterpillars of particular insect species. The caterpillars of butterflies, for example, each have their specific host: the swallowtail (*Papilio machaon*) the umbellifers, such as dill, caraway, carrot; the peacock butterfly (*Vanessa io*), the red admiral (*Vanessa atalanta*) and the small tortoiseshell (*Vanessa urticae*) the stinging nettle; the large white (*Pieris brassicae*) the cabbage species, and so on.
