This chapter discusses the relationships among lepidopteran evolutionary lineages based on changes in their morphological adaptation. It begins by discussing fossil records of Lepidoptera, followed by the morphological adaptations of ancient and subsequent lineages. The chapter then illustrates a theoretical scenario for the origins of angiosperm-feeding in basal lepidopteran lineages that led to radiations of Lepidoptera. It also describes the evolutionary origin of the present-day flora of western North America.

Keywords: evolutionary lineages; morphological adaptation; fossil records; Lepidoptera; angiosperm-feeding; western North America
