Coryphista meadii

Also known as Barberry Geometer, Barberry Looper, Barberry Looper Moth

Barberry geometers fly from late spring through autumn, resting with their intricately scalloped wings spread flat against tree bark or garden foliage. Caterpillars feed voraciously on barberry shrubs, chewing irregular notches along the leaves and stripping branches during population peaks. Multiple generations emerge each year across North America, with adults readily drawn to outdoor lights after nightfall.
