Identification
Small size (14–17 mm wingspan) distinguishes this from larger leaf-roller . The larval shelter—two or more oak leaves bound together in a flat 'sandwich' configuration—differs from the rolled or folded shelters of many related . lack strong patterning, making identification to species level difficult without dissection or molecular analysis.
