Erebidae: Catocala - Catocala amatrix
Turtle River State Park, Grand Forks County, North Dakota, USA

Size: Length ~ 3.5 cm
Hmmm...The uninterrupted white terminal band HW suggests C. concumbens, but the FW pattern seems different than other local concumbens. I'll need help with this specimen. Thanks for looking!

Moved from Underwings.

I would have thought this was Catocala amatrix
The white margin isn't useful as amatrix can show complete white edging (though I don't think concumbens can show it broken as amatrix can, so it is a one-sided feature as far as I can tell).

One point to note is the lower of the black lines on the forewing (the one with the "zigzag" on it). See how instead of abruptly ending at the wing margin it curves up and then follows the outer margin, which should be an amatrix feature. On concumbens it seems to consistently end without curving up or following the margin.

Thanks, James!
Thank you for helping with the identity of this moth. C. amatrix is a species that I do capture and photograph, but for some reason this specimen just looked a bit different. I'll append this photo of another specimen from our location so the key features you highlight make sense to me. Thanks you!
