Amyelois is a monotypic snout moth genus described by Hans Georg Amsel in 1956. Its single species, Amyelois transitella, the navel orangeworm, described by Francis Walker in 1863, is endemic to the tropical Western Hemisphere, including the southern United States. Its abundance in California increased greatly during the first half of the 20th century.
The wingspan is 9.7 to 10.9 mm. Adults are on wing from the end of March to the end of October in California.
The larvae are considered a commercial pest of a number of California crops, including walnut (Juglans regia), fig (Ficus carica), almond (Prunus dulcis) and pistachio (Pistacia vera).()
