The Ailanthus Webworm (Atteva aurea) is an ermine moth found commonly in the United States. This small, colorful moth resembles a true bug or beetle when not in flight, but when in flight it resembles a wasp. Its original range included the American tropics since its host tree (Paradise Tree) is found in this geographic range. It has expanded its range North as it has adapted to live and feed on Ailanthus altissima.
