An interesting fact to keep in mind is a single butterfly can lay 1,000 eggs but only five percent turn into butterflies. Birds, spiders, wasps and other insects eat both eggs and caterpillars. A more serious cause of declining butterfly and other pollinator populations is the use of neonicotinoids. Many plants and seeds have been treated with this chemical that is absorbed by, and remains in, every part of the plant, including the pollen and nectar that feed the pollinators. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and death. So keep this in mind when buying your plants and ask if they are neonicotinoid-free.
Butterfly eggs are smaller than the head of a pin. Black Swallowtails lay their eggs on parsley, dill, fennel and other herbs so look carefully before eating them. You may even find them on herbs purchased from farm stands or in the organic section of your grocery store. Other butterfly species have their own favorites. Caterpillars eat a tremendous amount before turning into a butterfly so it is nearly more important to plant more herbs or host plants, as they are called, than flowers.
