Frequently Asked Questions
No, it's a common name for many species of caterpillars (primarily moths) and some other insects that exhibit the leaf-rolling behaviour.
Yes, they are generally considered pests as their feeding can damage leaves, reduce photosynthesis, and spoil the appearance of ornamental plants and fruit crops.
Often, you see the rolled or folded leaf first. The insect itself is usually hidden inside its silken shelter during the day.
A leaf roller rolls or folds the leaf externally, while a leaf miner lives and feeds inside the leaf, creating visible tunnels or blotches within the leaf tissue.
