General characters. Adult: Labial palpus well tufted on ventral surface of second segment. Forewing elongate; apex rounded, falcate or produced; R4 and R5 stalked or separated, CuA1 and CuA2 remote, connate, or shortstalked from angle. Hindwing with Rs and M1 long stalked, M2 and M3 separated or stalked. Marked wing venation of Ypsolopha is shown in figure 2.

Male genitalia (Fig. 3 a): Uncus small, ill-defined, except developed in Y. albiramella Mann and Y. cajaliella Vives. Gnathos with long arms, forming a spoon-like ventral plate, densely covered with small teeth on ventral surface. Saccus developed. Anellus cylindrical, densely covered with short hairs or setae ventrally. Phallus with coecum penis; cornuti present, usually composed of two large thorns or two clusters of spines or microspines.

Female genitalia (Fig. 3 b): Intersegmental membrane between papilla analis and 8th abdominal segment moderate to long. Apophyses posteriores extremely long. Antrum small, roughly cup-shaped, sclerotized at base, in some species sclerotized throughout. Ductus bursae membranous, in some species sclerotized partially and/or granulous. Signum usually a band-shaped plate, often with one or two transverse ridges.

Biology. Moriuti (1977) and Agassiz (1996) reported the biology of several species from Japan and England respectively. Larvae are usually solitary, living in a small web among leaves. In some species, two or three larvae of the early instars live together in a common web. Larvae mainly feed on the plants of Pinaceae, Ulmaceae, Fagaceae, Celastraceae, Rosaceae etc. Pupation occurs in a spindle-shaped cocoon among leaves or among litter on the ground.

Distribution. Ypsolopha is distributed throughout all the geographical regions, with majority in the Palearctic and Oriental regions.
