The name ”leaf-roller” applies to the many species of caterpillars that roll leaves around themselves as they feed, creating a protective tube. Color and size vary with the species. Some leafrollers attack only one type of plant, while others eat numerous kinds. When disturbed, leafrollers wriggle backward and drop from the plant on a silken strand.
Target: Many plants.
Damage: Leaves are chewed on and tied together with webbing. Flowers and fruit may also be eaten.
Life cycle: Moths lay masses of eggs on plants; caterpillars hatch out, then feed and weave nests. The insects over winter as eggs or pupae on plants. The number of generations a year varies, depending on the climate and the pest species.
Notes: Control the pest before it takes refuge in rolled leaves. If damage is light, pick off rolled leaves or squash them in place.
