Amyelois transitella (Walker) (Lepidoptera: Pyralidae), the navel orangeworm, is an important pest of a wide variety of fruits and their seeds. We discovered and report for the first time A. transitella feeding on Sapindaceae in wild populations of U. speciosa (Endl.) in northeastern Mexico. We provide photographs of the plant, the adult, and the larval and pupal stages of the moth. Although A. transitella is a pest in other areas, it is not considered a pest in northeastern Mexico.
