Biology
Leafrollers are the caterpillar (larval) stage of several different moth species. These rather small caterpillars vary in color from brownish to pale or dark green. They generally have a shiny black or brown head and similarly colored "shoulder" plate. They roll leaves, "stitch" them together with silk, then feed within the shelter of the rolled leaf. When probed or otherwise disturbed they thrash about violently and try to lower themselves out of harm's way on strands of silk. They attack many trees, including most fruit trees. They may also damage fruit.
