Identification of lepidopteran larvae of agricultural importance. In Washington, the adult moth is active from April to September and has one generation a year. Photos are preferred of moths oriented head upward rather than at an angle. Larvae are not easily distinguished from the larvae of other tortricid leafrollers; only DNA testing is a certain identification method. The caterpillar is known for crawling onto a leaf and rolling itself up inside. FWL: 7.0-8.0 mm (male); 9.0-10.0 (female).

This resource includes interactive identification keys, images, diagrams, fact sheets, and a DNA sequence database. Sentinel larvae were used to determine both parasitoid identity and parasitism rate each month during the kiwifruit growing seasons in 2013/14 (16 orchards) and 2014/15 (12 orchards). The first larval instar has a dark brown head; all other instars have a light fawn head and prothoracic plate. The average head-capsule measurement over the period of development was taken for each .
