Identification

Distinguished from other Catocala by specific forewing pattern and hindwing coloration; precise identification requires examination of genitalia or reference to regional keys. The species name 'praeclara' and association with larval plants in Amelanchier, Crataegus, and Photinia can aid identification within its range.
