Fruittree leafroller

Archips argyrospila (Walker)

Lepidoptera: Tortricidae

The adult is red-brown with mottling (A). The translucent green caterpillar has a reddish to dark brown head and an amber to pale green thoracic shield edged with brown (B).

  • Damage

    Attacks apple and pear mainly, plus other tree fruits on occasion. A silky web usually ties together leaves and young, partially eaten fruit; injured apples have pronounced deformations at maturity (C).


    The insect seldom causes problems. When necessary, use broad-spectrum insecticides (which can simultaneously be directed against the plum curculio) and selective insecticides (Bacillus thuringiensis and insect growth regulators).
