Taxonomy
Superfamily: Tortricoidea Family: TortricidaeSubfamily: TortricinaeTribe: ArchipiniP3 Number: 620262.00 MONA Number: 3603.00
Comments: The genus Argyrotaenia contains approximately 100 described species, with most occurring in Nearctic and Neotropical regions. Thirty-six species are currently recognized in North America.
Species Status: This wide-ranging species is geographically variable. According to Obraztsov (1961), specimens from North Carolina and Florida belong to a form in which the forewing markings are browner, and mixed occasionally with black. The specimens from North Carolina show, in addition, a tendency to develop an elongate, black, longitudinal spot crossing the median fascia of the forewings on the level of the discal cell.
Identification
Field Guide Descriptions: Leckie and Beadle (2018)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Freeman (1960)Technical Description, Immature Stages: Freeman (1960); Maier (2004)                                                                                 
Adult Markings: The following description is based in part on that of Freeman (1960). The head, labial palp, and thorax are light brown to reddish-orange. The forewing patterning and coloration are variable, and the following description summarizes the general trends. The forewing ground color varies from pale buff to light pink, purplish brown, or orange. It is overlaid with darker reddish-brown lines and bands. The basal patch varies from reddish-brown to light pinkish purple and typically has two darker reddish-brown, angulated lines. These can vary in size and shape, are often fragmented, and may even fork. A dark, oblique median band is present that is typically lighter in the middle. The middle portion often has a light purplish to pinkish-purple cast, and is bordered on both edges with darker, irregular, reddish-brown coloration. Both the posterior margin of the basal patch, and the anterior and posterior margins of the central band, are finely lined with white. A large costal spot is present beyond the median band that is reddish-brown, with darker inner and outer edges. A matching elongated spot is found towards the tornus. These are often connected to form a band. Beyond the costal spot, there are one or two short, dark, reddish-brown lines that extend inward from the costa. The forewing fringe is light reddish brown, and the hindwing is smoky and becomes lighter towards the base. The hindwing fringe is light with a dark basal line, and becoming tawny towards the apex. This species is somewhat similar to A. pinatubana, but the latter is more drab overall and lacks reddish-brown bands that are lined with darker borders. In addition, both the posterior edge of the basal patch and the anterior edge of the median band tend to be more straight-edged relative to those of A. tabulana.
Wingspan: 13-17 mm (Freeman, 1960)
Adult Structural Features: Obraztsov (1961) noted that the genitalia of A. tabulana and A. velutinana are indistinguishable.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae in populations in the US feed on pine needles. Freeman (1960) studied Canadian populations and reported that the larva first mines from the tip of a needle almost to the base. Later it ties two or more needles together into a bundle or tube, lining the interior with silk. It feeds within the bundle, and eventually incorporates additional needles or makes a new bundle from the current growth. In late summer or early fall it drops to the ground and pupates in a flimsy cocoon in the leaf litter. Maier (2004) studied New England populations and noted that the older larva lives in a silk tube within groups of pine needles that are bound together to form a tube-like shelter. The larva chews off the exposed portions of the needles and feeds on these, which creates a characteristic tube that is shorter than the surrounding undamaged needles. The mature larva may be as long as 15 mm and has a dull greenish body and orange-brown lobes on the head. In New England there are two generations per year, with the first in June and July and the second in September and October. The larvae from the second brood overwinter within the tubes. Population in North Carolina chew the ends of the tubes off as described by Maier (2004).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Argyrotaenia tabulana is found in North America, including much of southern Canada from British Columbia eastward to Nova Scotia. It occurs in Montana, Wyoming, and Washington (Freeman, 1960), and throughout much of the eastern US. In the eastern US the range extends from Maine southward to Florida and westward to eastern Texas, eastern Oklahoma, Illinois, and Michigan. This species occurs statewide in North Carolina.
