Antheraea polyphemus (Cramer, 1776) - Polyphemus Moth

Antheraea polyphemusAntheraea polyphemusAntheraea polyphemusAntheraea polyphemus
Taxonomy
Superfamily: Bombycoidea Family: SaturniidaeSubfamily: SaturniinaeTribe: AttaciniP3 Number: 890070 MONA Number: 7757.00
Comments: The only member of its genus in the eastern United States (Antheraea oculea occurs in Arizona and New Mexico -- Tuskes et al., 1996)
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1923), Ferguson (1972), Tuskes et al. (1996)Technical Description, Immature Stages: Forbes (1923), Ferguson (1972), Covell (1984), Tuskes et al. (1996), Wagner (2005)                                                                                 
Adult Markings: Adults are unmistakable. With a wingspan of 4-6 inches, this is one of our largest native moths. Its yellowish-brown or tan color and large ellipical eyes-spots distinguish it from the similar-sized Cecropia Moth, which has red bands on its wings and body and has crescent-shaped discal spots.
Wingspan: 125 mm (Forbes, 1923)
Adult ID Requirements: Unmistakable and widely known.
Immatures and Development: The large green larvae are also quite distinctive. Although similar to those of the Luna Moth (Actias luna), they lack the lateral yellow stripe possessed by that species and have vertical yellow stripes located in the middle of the abdominal segments rather than in between (Ferguson, 1972, gives additional details). Cocoons are often encountered attached to trees or shrubs or fallen on the ground. Their thick ovoid shape is quite distinctive and can serve as the basis for site records for this species.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Occurs state-wide (Brimley, 1938)

Flight Comments: Appears to be single-brooded in the mountains but shows a distinctly bimodal flight pattern in the Coastal Plain and possibly the Piedmont.
Habitats and Life History
Habitats: Occurs in virtually all types of forests in the state, from maritime forests on the barrier islands (e.g., Fort Macon) to the high elevation forests of the mountains (e.g., Great Smoky Mountains National Park). It is also frequently encountered in wooded residential areas.
Larval Host Plants: Feeds on many species of hardwood trees and shrubs, but not on pines as has been previously reported (D. Schweitzer, pers. comm. to S. Hall). Brimley (1938) reported that it feeds primarily on elm and maple in North Carolina. Wagner (2005) stated that favored host plants include members of the birch, rose, and willow families (Wagner, 2005); Tuskes et al. (1996) also list oak as a favorite. Other commonly used host plants include ash, dogwood, hazel, and hickory (see Ferguson, 1972, for a more extensive list). As of 2023, we have observed it feeding on oak, maple, hickory, elm, chestnut, hornbeam, and rose, and have found cocoons on a wide range of other plants. - View
Observation Methods: Comes well to 15 watt UV lights and also to incandescent light to some extent. Adults do not feed and consequently are not attracted by bait. Larvae can be detected in low trees and shrubs through their droppings. Cocoons can often be found attached to low trees and shrubs. Larvae are easy to rear in captivity (see Tuskes et al., 1996).

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands
Comments: Populations are locally vulnerable to the effects of weather, outbreaks of disease, parasites, and predators, and to the effects of pesticides. However, given the commonness of their host plants, wide habitat range -- including suburban areas -- and statewide distribution, this species can easily recover from those losses and appears to be secure in the state for the foreseeable future. In the Northeast, this is one of the few species of Saturniid that appears to be increasing in number (Wagner, 2012).
