Biggest one of the 10 at lights

Consistently the most common Catocala at my light, this night was perhaps the most I have seen. At one point, I counted 78 individual catocala and though there may have been ~7-8 C.amica/lineella mixed in, the only other species present was this one. Captured a few different photos to show some of the numbers.

Based on the small size (FW < 3mm), and the complete dorsal white stripe which extends to the fringe of the FW.
