Chimoptesis pennsylvaniana (Heinrich) (Tortricidae: Olethreutinae: Eucosmini)
Common names: filigreed moth
Note: As the name pennsylvaniana was only a suggestion for this species by Kearfott (1907), the authorship belongs to Heinrich (1923), who was the first to afford it taxonomic rank, even though he interpreted Kearfott’s suggested name to be a valid subspecies designation.
FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 6.5-8.0 mm
Head white; thorax dark brown to black; tegulae white to pale green; forewing predominantly dark brown to black, dorsaldorsal:
upper, to the top, on the back 
margin with irregularly-shaped green or occasionally white band running from base to tornustornus:
the junction of the termen and dorsum of the wing 
, only interrupted briefly by a black streak near tornustornus:
the junction of the termen and dorsum of the wing ; costal strigulaecostal strigulae:
small, usually pale, semirectangular marks along the costa 
with similar shades of green or white; male with costal fold present; hindwing brown.
Male genitalia are characterized by uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
obsolete, sociisocii:
a pair of lightly sclerotized setose lobes
rectangular, cuculluscucullus:
the distal portion of the male valva
well-developed. Female genitalia are characterized by a ring-like sterigmasterigma:
the sclerotized region surrounding the female ostium bursae 
, a sclerotizedsclerotized:
hardened; usually in reference to larval structures or adult genitalia 
, cylinder-shaped posteriorposterior:
after, to the rear, toward anal end 
portion of the ductus bursaeductus bursae:
a membranous tube connecting the ostium bursae to the corpus bursae
; and two thorn-like signasignum:
a sclerotized projection or patch on the interior of the corpus bursae
.
Larvae are unknown for all species of Chimoptesis at present.
Adults are more similar to Epinotia albicapitana (Kearfott) than to other species of Chimoptesis. Chimoptesis pennsylvaniana can be separated from E. albicapitana by the spring flight time and eastern distribution. E. albicapitana is a fall-flying western species; any eastern records of E. albicapitana almost undoubtedly are misidentifications of C. pennsylvaniana.
Chimoptesis pennsylvaniana has been reared from oak (Quercus spp). Adults have been collected from January into early May, suggesting one or perhaps two generations per year.
