Taxonomy

Archips georgiana (Walker) (Tortricidae: Tortricinae: Archipini)

Adult Recognition

FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 6.0-9.0 mm (males); 9.5-11.5 mm (females)

Head orange-yellow, thorax similarly colored but with some red scaling intermixed; FW with ground color deep red and orange, fasciaefascia:
a dark transverse band on the forewing
pale orange-yellow, often heavily suffused with silver or gray-pink scaling; male with costal fold present; HW dark brown.

Male genitalia are characterized by broad, circular valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
; moderate, finger-like uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; and pistol-shaped phallusphallus:
the male intromittent organ (penis); see "aedeagus"
. Female genitalia characterized by bowl-shaped sterigmasterigma:
the sclerotized region surrounding the female ostium bursae
and long, dagger-like signumsignum:
a sclerotized projection or patch on the interior of the corpus bursae
.

Larval Morphology

The larva of A. georgiana lacks a detailed description in the literature. The following account is summarized from MacKay (1962a), but size and chaetotaxychaetotaxy:
the arrangement of setae (in reference to Lepidoptera larvae), often depicted on a "setal map"
were not described owing to limited material.

Head light brown; prothoracic shieldprothoracic shield:
a sclerotized plate on the dorsal surface of the prothorax
green with brown pigmentation laterally; legs pale; pinaculapinaculum:
flattened sclerotized plates on a caterpillar that bear the setae
green or brown; anal shieldanal shield:
a sclerotized plate on the dorsal surface of the last abdominal segment (in larvae)
brown; anal fork well-developed.

Similar Species

Adults of A. georgiana are more similar to Choristoneura houstonana than to other species of Archips. Both are primarily southern species. The fasciaefascia:
a dark transverse band on the forewing
in A. georgiana tend to be fairly complete, whereas in C. houstonana they tend to be broken into smaller, round blotches. Males of A. georgiana have proportionally larger valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
and a much narrower uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
than C. houstonana.

Biology

Larvae are leaf-rollers on hickory (Carya ssp.), oak (Quercus spp.), and blueberry and relatives (Vaccinium spp.). Little else is known about their life cycle. Adults have been recorded from March to June.

Distribution

Archips georgiana is distributed in the southeastern United States, from Missouri and North Carolina south to Texas and Florida. A few scattered northern records exist, but these require verification.
