Moths in the family Tortricidae are commonly called Tortricid, tortrix, or leafrollers, after their caterpillar's habit of shelter-building by folding or rolling the leaves of its host plant. Tortrix caterpillars employ a wide variety of feeding techniques, all damaging to the victim: root boring, fruit boring, seed predation and flower-feeding.

While tortricids are known primarily as agricultural pests, a few have been used as biological control agents of invasive plant species. [1]
