Habitat
Members of this tribe are primarily found in temperate regions, associated with deciduous forests, orchards, and areas where their plants grow. Many are arboreal, with larvae developing on trees and shrubs.
Distribution
Temperate regions of the Northern Hemisphere, particularly Europe, Asia, and North America.
Seasonality
are active primarily in spring and early summer, coinciding with flowering and early fruit development of plants. Larval stages occur during late spring through summer.
Diet
Larvae feed on plant tissues, particularly developing fruits, leaves, or stems of rosaceous plants (Rosaceae). Some are specialized fruit feeders, while others consume foliage.
Host Associations

Life Cycle
Complete with , larval, pupal, and stages. Eggs are inserted into plant tissue. Larvae develop within fruits, under of leaves, or in stems. occurs in soil or in plant tissue. Many have one per year ().
Behavior
Larvae often feed concealed within plant tissues, making them difficult to detect. Some exhibit leaf-rolling or fruit-mining . are generally short-lived and focused on .
Ecological Role
Larvae function as herbivores, sometimes reaching pest status in orchards. They serve as prey for and other natural enemies.
Human Relevance
Several are significant agricultural pests, particularly in apple, pear, and cherry orchards. Larval feeding causes fruit distortion, premature drop, or cosmetic damage. Some species are targets of programs.
