navel orangeworm
Amyelois is a monotypic genus of snout moths (Pyralidae) containing a single species, Amyelois transitella, commonly known as the navel orangeworm. The species is endemic to the tropical Western Hemisphere, including the southern United States, and has become a major agricultural pest in California nut orchards. Its abundance increased substantially during the first half of the 20th century.
