Celypha Hübner
Type species: striana Denis and Schiffermüller
DIAGNOSIS
External characters:
Venation:
Forewing: All veins separate; chorda originating equidistant from R 1 and R 2, extending to R 5; M to base of M 2.
Hindwing: M 3 and CuA 1 connate or separate.
Forewing shape and markings:
examples of Celypha spp.
Forewings variable.
Additional characters:
Posterior tibia with large pencil of scent scales.
Genitalia:
Male:
male genitalia C. lacunana
Uncus hairy; varying from a weakly sclerotized, subtriangular process to a rigid rod; socius drooping or lateral, hairy, apical lobe reduced; tuba analis membranous, often with ventral sclerite and well-developed anterior juncture. Valva broad basally; sacculus more or less expanding posteriorly (forming a rounded angle), with ventral or subventral clusters of spines or bristles, occasionally situated externally or on lobes or processes; cucullus slender, often broadening terminally; fold usually distinct, provided with apical lobe; posterior edge of basal opening forming a distinct rib in several species.
Female:
female genitalia C. lacunana
Sterigma large, with convex median part (usually deeply incised posteriorly) and large lateral wing-shaped plates. Colliculum variable in length; ductus bursae simple, exceptionally provided with a median sclerite, ductus seminalis situated on posterior part; ductus bursae with single, aciculate or granulate, concave, signum.
Early stages:
Swatschek, 1958, provides a diagnosis for the larvae of over 20 species of 'Olethreutes'' (in fact larvae of several genera such as Hedya, Celypha, Pseudosciaphila, Olethreutes, Phiaris, Argyroploce, Apotomis, Stictea, Eudemis and Orthotaenia).
Crochets on abdominal prolegs biordinal; D1 and SD1 on separate pinacula on A9, or SV group bisetose on A7. Sutura coronalis significantly longer than greatest width of adfrontals, or L1 and L2 more or less equal in length.
Biology:
One or two generations yearly; larvae often in roots or bases of stems, or spinning the leaves, flowers or shoots of various plants. Celypha lacunana is a pest of strawberry.
Distribution:
Palaearctic and Nearctic Regions.
