Heterocampa biundata

Thanks, Jason.
I'm sure you are correct, but could you tell me what you see that clinches the ID?

While the maculations are faint, the orange markings are present and correct for biundata. For instance, right at the inner margin of the basal area of the FW, the orange spot marking is pretty clear, and then you can see just enough of the orange wavy AM line and a bit of the PM line. And on the left FW you can see the prominent black arrows/wedges that make up the ST line.

It's a bit harder to see, but visible enough for a positive ID. Hope that helps.
