Archips negundana (Dyar) (Tortricidae: Tortricinae: Archipini)
Common name: larger boxelder leafroller moth
Synonyms: nugundana (Cacoecia)
FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 8-12 mm
Head, thorax pale yellow to pale brown; FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe with ground color pale yellow to orange-brown, fasciaefascia:
a dark transverse band on the forewing
orange-brown to pale brown, sometimes obsolete; male with forewing costal foldforewing costal fold:
a flap or fold at the base of the forewing that contains specialized sex scales
present; HW usually shining white, but occasionally brown.
Male genitalia are characterized by valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
obliquely triangular; uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
moderate, finger-like; phallusphallus:
the male intromittent organ (penis); see "aedeagus" 
pistol-shaped. Female genitalia are characterized by papillae analespapillae anales:
the female ovipositor lobes 
moderate; sterigmasterigma:
the sclerotized region surrounding the female ostium bursae 
bowl-shaped; ductus bursaeductus bursae:
a membranous tube connecting the ostium bursae to the corpus bursae
long, membranous; signumsignum:
a sclerotized projection or patch on the interior of the corpus bursae
long, dagger-shaped.
The following account is summarized from MacKay (1962a).
Mature larva 19-22 mm in length, width of head 1.6-2.0 mm. Head pale with some black pigmentation laterally (first instar larva with head entirely black). Body pale, unicolorous; pinaculapinaculum:
flattened sclerotized plates on a caterpillar that bear the setae
small, concolorous with body. Anal fork present. SV group on A1, 2, 7, 8, 9 variable, but usually 3:3:3:2:2.
A more complete description of larval chaetotaxychaetotaxy:
the arrangement of setae (in reference to Lepidoptera larvae), often depicted on a "setal map"
is available in MacKay (1962a).
The pupa is approximately 10 mm in length, pale green when first formed, becoming browner over time (Parker & Moyer 1972).
Archips negundana is most similar to A. semiferanus, which tends to be a much darker species, but some paler specimens may not be able to be separated. Both male and female genitalia are similar, but females exhibit differences in the scales on the ventralventral:
lower, to the bottom, on the under side
surface of the abdomen.
The following account is summarized from Parker & Moyer (1972).
In Utah, A. negundana completes a single generation per year. Eggs are laid in scale-covered, flattened masses of an average of 30 eggs per mass. Eggs hatch in early May after overwintering and larvae begin feeding socially on the same leaf for the first two instars. Third instar larvae become solitary and roll and web leaves of the host plant together. Most larvae pupate by mid-June. Adults eclose in approximately 7-12 days and fly and mate into late July. Eggs are laid in the crevices on branches and trunks of trees.
Host plants
Maple and boxelder (Acer spp.) appear to be the preferred host, but other host records exist. Some of these may represent misidentifications of A. semiferanus and require verification.

Archips negundana is broadly distributed in North America, but many records may represent misidentification in the literature with A. semiferanus, so the true range of this species is not clear.
