Lepidopteran larvae possess a robust digestive system featuring a multitude of hydrolytic enzymes that are able to accommodate an often highly polyphagous diet. Additional digestive complexity arises from the peritrophic matrix (PM) which encases the food bolus and compartmentalizes digestive processes. This review focuses on genomic and proteomic studies from several species that have identified what is likely to be the entire complement of proteins associated with the lepidopteran PM. In the process, a basal set of structural proteins common to the lepidopteran PM is described, and the roles of these proteins in PM structure and function are discussed. Finally, updated models for PM molecular architecture and formation which incorporate information about recently discovered proteins are provided.
