Life Histories and Conservation Matters of Stiriini (Noctuidae: Stiriinae) from the American Southwest

Abstract

Stiriinae as presently circumscribed include two tribes, the Annaphilini and nominate Stiriini, that have radiated over the American West and Mexico, where more than 90% of the global species diversity is believed to be endemic. Here we provide life history information for 56 species of Stiriini that occur north of Mexico - 40 are figured for the first time. For each species, we provide a brief summary of the known distribution north of Mexico, its seasonal phenology, known larval hosts, and diagnostic features. Images of a penultimate or last instar are provided for all but one species. Additionally, we include a brief characterization of Stiriini larval morphology, summarize common elements of Stiriini larval biologies, and identify 16 species that might be worthy conservation targets.
