Coleotechnites variiella (Chambers, 1872) - No Common Name

Taxonomy
Superfamily: Gelechioidea Family: GelechiidaeSubfamily: GelechiinaeTribe: GelechiiniP3 Number: 420753.00 MONA Number: 1833.00
Comments: The genus Coleotechnites includes 49 very small species that occur in North America. Most species are specialists on conifers and tend to use on a single genus of host plant. Many of the Coleotechnites species have almost identical genitalia that are not very useful in delineating closely related forms (Freeman, 1960; 1965). Freeman (1960) noted that host plants and the mining characteristics often provide the most reliable way to identify closely related species.
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1923, as Recurvaria variela)                                                                                 
Adult Markings: Despite substantial variation between individuals, this is a distinctively marked Coleotechnites. Note the white palp that lacks annulations, the four black spots along the base of the costal fringe, and the white angulated fascia in the PM region. The following description is based primarily on those of Chambers (1972, p. 187) and Forbes (1923). The head, antenna, and thorax are white. The labial palp is white and lacks annuli, and on some individuals the outer sides may have a slight yellowish cast. The forewing ground color is white, but becomes progressively overlain with golden yellow and fuscous dusting on the apical half. Individuals vary in the degree of dark dusting, which in turn can affect the overall patterning. A narrow line of dark dusting often occurs along the costal margin from the wing base to near one-half the wing length, where it meets a diffuse, curved golden brown bar that curves towards the middle. The bar extends posteriorly and often fuses with the terminus of a second, similar bar that begins on the costa at around three-fourths. In many specimens the region between the bars is completely filled with golden yellow and/or darker dusting and the bars are not evident. There are usually four conspicuous black spots at the base of the costal fringe that have whitish scales immediately in front. An outwardly angulated white fascia is usually present (sometimes incomplete) that begins on the costa just before the anteriormost spot. It projects posteriorly before sharply angling anteriorly to the dorsal margin. The other conspicuous mark is a black scale tuft that is located along the fold about three-fourths the wing length. It often has a few raised whitish scales associated with it.
Wingspan: 8 mm (Forbes, 1923)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Busck (1903a) reared a large series from Bald Cypress. The larva ties a few needles together and feed between them, eventually pupating in silk-lined tubes within similar shelters (Eiseman, 2019).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Coleotechnites variiella is found in the eastern US from the Washington, D.C. area southward to Florida, then westward along the Gulf Coast states to eastern Texas and Oklahoma. The range extends northward up the Mississippi Valley to southern Illinois, with a few scattered in Indiana, southwestern Ohio, and Kentucky. As of 2021, we have records only from the northeast corner of the Coastal Plain and the eastern Piedmont.
