Striglina scitaria, the daincha leaf webber,[1] is a species of moth of the Thyrididae family. It is found in Taiwan, Japan, India, Sri Lanka, Myanmar, the Andamans, Borneo, New Guinea, Fiji and Australia. It is a major pest which mainly attacks on legume crops.[2]

Description

Wingspan is about 3 cm. Adults are reddish ocherous, with wings evenly striated with brown. An oblique reddish-brown line runs from apex of forewing to the inner margin of hindwing before the middle. Ventral side is with a dark spot at end of cell of forewing. The oblique line coming out as black streaks ventrally. In some subspecies, there is a line on the hindwing from the same point on costa as the oblique line and curved to inner margin above anal angle or oblique to outer margin before anal angle. Larva are olive colored. First somite ocherous and head is black. There are few short distal hairs and series of transverse black dots from second to terminal somite.[3]

Ecology

The larvae feed on Sesbania bispinosa, Cassia corymbosa, Notonia grandiflora, nia grandiflora, Combretum indicmu, Kleinia grandiflora and Quisqualis indica.[4] Young larvae twist the terminal portion of a leaflet to form a small cone. During growth, the larva webs together several leaflets, creating a tunnel in which it lives and pupates.[5][6]
