This is a butterfly field guide designed for the Allens Pond Wildlife Sanctuary in Westport, MA, a part of the Massachusetts Audubon Society. The guide details ten species that appear in the area. For each butterfly, I illustrated each phase of its life cycle from egg to full-grown adult so that users can identify a butterfly in any phase. Each butterfly also includes a short description and a drawing of its larval plant. The purpose of the project was to create something beneficial to Allens Pond and to lend visitors a greater insight into and appreciation for the area. Working on this project, I gained valuable experience in working with clients and incorporating their needs into the project.
