Butterfly Gardening in the East Bay

There are many types of butterflies and closely related insects. In fact, about seven percent of all life forms on Earth are members of the Order Lepidoptera, including butterflies, skippers and moths. 

Of the thousands of butterfly species worldwide, the East Bay (Alameda and Contra Costa counties) hosts about 100 species. Most of these are regular visitors, although a few are associated with unique conditions of soil and water, and almost all require a few simple things:

Butterflies are relatively short-lived, varying from weeks to months in our temperate climate zone and their lifecycle from egg to adult allows only one or two generations per year, depending on the species. Most are visitors passing through our area, not permanent residents of our gardens. So, our challenge is to make them welcome guests!

Getting started with butterfly gardening

Attracting butterflies means serving their needs at each stage of their lifecycle, so think about providing green plants as places to lay eggs, food plants for the caterpillars (larvae), plants and places to form the chrysalides, and nectar plants for the adults. This sounds like a lot, but it can be accomplished with some good planning.
