Cydia lacustrina

Appearance

FEMALE: Head. Length of labial palpus segment 2 approximately 0.9 eye diameter, segment 3 approximately 0.3 length of segment 2; scaling spreading, obscuring part of segment 3; scaling of palpus, front, and crown light brown. Thorax. Dorsal scaling brown, darker than head, most scales white-tipped; venter shining white, femora varying from pure white to light brown, tibiae and tarsi light brown banded with white. Tegula white anteriorly and posteriorly, brown medially. Forewing. Length 8.4 to 9.4 mm, 2.7 to 3.1 times width at geatest dimensions; pattern as in Figure 1, costal area marked by approximately 10 apically angled white fasciae tinged with brown, dorsal area with fewer but wider white fasciae forming conspicuous markings near middle and tomus, one or two metallic fasciae in medial area of apical third; fringe white to brown, a black line extending around termen; underside of forewing brown, paler than upper side. Veins Cul, M3, and M2 approximate at termen. Hindwing. Broader than forewing; apex acute, termen round; ground color brown, fringe white; underside of hindwing brown, paler than upper side. Veins Cul and Ma short stalked. Abdomen. Dorsal scaling shining brown, venter paler brown; genitalia as in Figure 3, sterigma rectangular in outline, caudal margin of ostium with a V-shaped indentation from sterigma, ductus bursae short, asymmetrical, with sleeve sclerotized % of its length; anterior apophyses longer than posterior
apophyses; two thom-shaped subequal signa as in L. gallaesaliciana (Riley).
MALE: Unknown. It will probably resemble the female exteriorly as sexual dimorphism is not pronounced in Laspeyresia. Like the female, genitalia may resemble those of
L. lautiuscula Heinrich.
