Atteva punctella |
The Ailanthus webworm, Atteva punctella, is an ermine moth now found commonly in the United States.
There is some uncertainty about the origin of the Ailanthus webworm, but it is thought to be native to South Florida and the American tropics, with the original larval host plant, the Paradise Tree ( Simarouba glauca ). Tree-of-Heaven ( Ailanthus altissima ), a tree originally from China, has been widely introduced and Atteva punctella has jumped to this new host plant (giving it its common name, Ailanthus webworm). The moth does not survive cold winters, but migrates north each year so it is commonly seen in summer throughout the continental US, and occasionally eastern Canada.
Larvae produce nestA nest is normally built by birds to hold their eggs and provide a home for their offspring. They are usually made of some organic material such as twigs, grass, and leaves. Generally each species of bird has a distinctive style of nest. Nests can be founs on the host plant by pulling two to three leafletA leaflet in botany is a part of a compound leaf. A leaflet may resemble a complete leaf, but it is not borne on a stem as a leaf is, but rather on a vein of the whole leaf. Compound leaves are common in many plant families. For the publishing use of thes around a network of loose webbing. Then they consume the leaflets. The caterpillarThis article is about insect larvae. For the company, see Caterpillar Inc. for the vehicle locomotion system, see caterpillar track. A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths). Caterps have a wide, light greenish-brown stripe down their backs and several thin, alternating white and olive-green stripes along their sides. The adult mothA moth is an insect closely related to the butterfly. Both are of the order Lepidoptera. People who study or collect these insects are called lepidopterists. Most species of moths are nocturnal, but there are crepuscular and day-flying species. They can b visits flowerA flower is the reproductive organ of those plants classified as angiosperms ( flowering plants; Division Magnoliophyta). The function of a flower is to produce seeds through sexual reproduction''. For the higher plants, seeds are the next generation, ands and is a pollinatorA pollinator is the agent that moves pollen from the male anthers of a flower to the female stigma of a flower to accomplish fertilization or syngamy of the female gamete in the ovule of the flower by the male gamete from the pollen grain.

A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i. is not native), become by some, although it is still sold by nurseries as yard plant, mainly because it will grow in pollutedLachine Canal, in Montreal, is badly polluted Pollution is the release of harmful environmental contaminants, or the substances so released. Generally the process needs to result from human activity to be regarded as pollution. Even relatively benign prod or otherwise difficult places. Atteva punctella can be a minor pest in nurseries, although it rarely does serious damage.
