Taxonomy
Superfamily:
Bombycoidea		 Family:
Saturniidae		Subfamily:
Caratocaminae		P3 Number:
890022		 MONA Number:
7715.00		 Other Common Name:
Green-striped Mapleworm
Comments: The only member of its genus (see Ferguson, 1971, for its separation from Anisota). Several color forms have been described, one of which -- alba, a nearly all white form -- Ferguson recognized as a distinct subspecies. Only the typical bicolored form occurs in North Carolina, however.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1923), Ferguson (1971), Tuskes et al. (1996)Technical Description, Immature Stages: Forbes (1923), Ferguson (1971), Covell (1984), Tuskes et al. (1996), Wagner (2005)                                                                                 
Adult Markings: The bright yellow and pink adults are nearly unmistakeable. Only the Pink Prominent (Hyparpax aurora) and Primrose Moth (Schinia florida) are similar in color, although usually smaller. The subterminal area is yellow in S. florida, but red or pink in both Dryocampa and Hyparpax. The thorax of Dryocampa is completely yellow-orange, whereas in Hyparpax there is usually some pink color (Covell, 1984). The antemedian line is somewhat smoothly curved in Dryocampa but sharply angled in Hyparpax (Covell, 1984).
Wingspan: 40 mm, males; 50 mm, females (Forbes, 1923)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae are very distinctive: they possess a pair of thoracic horns similar to those of Anisota larvae, but are striped with green and pale bluish-green stripes and often possess a pink or rosy patch below the spiracles at the rear end of the abdomen (Ferguson, 1971; Wagner, 2005).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Occurs statewide (Brimley, 1938), except, perhaps on the Outer Banks and other barrier islands

Flight Comments: Probably double-brooded over most of the state (Brimley, 1938)
Habitats and Life History
Habitats: Maples -- particularly Red maple -- occur in nearly every type of forested habitat in eastern North America. Not surprisingly, Dryocampa has been found in a wide variety of forests, ranging from swamps and peatlands in the Coastal Plain, to river bottomlands and mesic slopes throughout the Piedmont and Low and High Mountains. In addition to natural areas, it also occurs commonly in wooded residential area. We have no records for the Outer Banks and other barrier islandes, however, including Nags Head Woods, Fort Macon State Park, and Bald Head Island, all of which have had intensive moth surveys.
Larval Host Plants: Feeds mainly on maples (Acer spp.), including Red maple (A. rubrum), Sugar maple (A. saccharum), Silver maple (A. saccharinum), and Box elder (A. negundo) (Ferguson, 1971). In some areas, however, it has also been found on oaks, including Turkey oak (Q. laevis) (Ferguson, 1971). In North Carolina, we have found larvae primarily on Red Maple, with a few records from oaks, including White Oak (Q. alba). - View
Observation Methods: Adults of both sexes come well to lights, including both blacklights and incandescent. Early instar larvae are gregarious, and in outbreak years can be quite conspicuous. Pupation occurs underground.

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 localized losses. Unlike several other species of Saturniids, Dryocampa has remained abundant in the Northeast (Wagner, 2012) and may not be as vulnerable to the effects of Compsilura parasitism.
