Ailanthus Webworm Moth
Adult Ailanthus moth is commonly found nectaring at goldenrod.

Ailanthus webworm moth is the lone representative of this genus in North America. This very common moth ranges from Ontario and New York south to Florida, west to Nebraska and Texas, and south into Mexico. Gregarious larvae are found in webs on their host plant, Ailanthus.

Atteva aurea (Fitch, 1857). Taxonomic notes: This moth belongs to a species complex that was recently split; see Wilson 2010 in references. Deiopeia aurea Fitch, 1857 = Atteva aurea is the proper name for the North American temperate forest moths. Tinea pustulella Fabricius = Atteva pustulella - is now restricted to the tropical rainforest species.

Phalaena Tinea punctella Stoll, 1781 = Atteva punctella - was commonly used for this species but was never valid because it was a junior homonym of Phalaena puntcella Linnaeus. It also refers to the tropical species. Authorship of P. punctella is sometimes listed as Cramer, 1781. Cramer died before his description was officially published. [2]
