Parallel waves of brown lines run across the Scallop Moth, but it's the bottom of the wings that are so noteworthy.
The Scallop Moth have rounded, undulating edges that are most emphasized on the hindwings. Ripples of varying shades of brown also curve across all the wings. Some moths may even have red, purple, or yellow tones.
Caterpillars are brown or green with three white, angled marks along the sides. The sides of segments stick out like triangles. The top of the body also has raised ridges that look like diamond-shaped scales from above. They feed on gooseberry, maple, apple, and birch. One or two broods can be produced each year depending on the region.
