The updated and expanded version of the Tortricids of Agricultural Importance (TortAI) website. Here you will find comprehensive resources for identifying adults and larvae of exotic tortricids that threaten agriculture in the United States as well as similar-looking, native or already-established exotic species. This resource is not designed to identify every tortricid, but rather to reliably identify major pests and common non-pest species. In total, Tortricid ID covers 214 target and non-target species in detailed fact sheets and interactive identification keys. To begin, click on one of the menu items at the top of this page. Please visit the About Tortricid ID page for information on how to use the keys, fact sheets, and other sections of the site.
