Stretch's Underwing, Catocala stretchi = junctura (wingspan: 75-80mm) flies in California, probably to Arizona. There is also a record for Cook County, Illinois.
Beutenmüller described the form "sierrae" in 1907, and he also described the subspecies margherita in 1918. The subspecies margherita flies in Arizona. Image courtesy of Bruce Walsh.
