Tortricidae

Tortricidae is a large family of moths whose larvae often roll or tie leaves and feed within them. Many species are agricultural pests, while others feed on seeds, fruits, or other plant parts.

Lepidoptera: The insect order comprising moths and butterflies, distinguished by wings covered with tiny scales. Tortricidae is one family within this order of scale-winged insects.
Leaf-rolling insect: An insect whose immature stage folds or rolls plant leaves into a shelter. Many tortricid caterpillars construct shelters this way, though leaf-rolling occurs in other insect groups too.
Codling moth: A tortricid moth whose larvae burrow into apples and pears, damaging the fruit and its seeds. It is a prominent fruit pest and a well-studied example of the family's economic impact.
Spruce budworm: A collective name for tortricid moth larvae that feed on spruce and fir buds and foliage. These forest pests show that tortricid damage extends beyond fruit and field crops.
Pyralidae: A large family of moths whose larvae include borers, webbers, and pests of stored products. Pyralid larvae can resemble tortricids in concealed feeding, but the families are distinct.
Moth: A lepidopteran insect that is generally distinguished from butterflies by traits such as antennae and activity patterns. Tortricids are moths, sharing the group's basic adult body plan.
Leaf tying: The fastening of plant leaves together, often by an insect larva using silk. Tortricid larvae can bind leaves into protected feeding sites.
Oriental fruit moth: A tortricid moth whose larvae damage peach shoots and fruits and also attack other fruit crops. Its changing larval targets illustrate how a tortricid can damage different plant tissues.
Light brown apple moth: A polyphagous tortricid moth native to Australia whose larvae feed on many plants. Its unusually broad host range has made it a notable invasive-pest concern.
Gracillariidae: A family of small moths whose larvae commonly mine leaves or form leaf shelters. Its leaf-feeding larvae offer a comparison with tortricid leaf rollers.
