I tried to take the associated caterpillar images through the key to larvae in Wagner & McCabe(1)(2011)...to view the key, click the "Larval Identification" tab in the right column here.

I found some ambiguity in navigating the key there, but my best shot ended at Z. jaccusalis...with runners-up Z. protumnusalis and Z. laevigata (and maybe even Z. theralis?). Like I said there was some ambiguity in the process ;-) But at least it's down to 4 out of 11 (assuming this is among the species covered in that key!).

But note that the MPG range maps and reference images (linked to the names in the paragraph above) do suggest Z. jaccusalis as the best fit among those four.

PS: I hope there are some BG experts available to take a look at this post. With larva, pupae, and adult...at least they'll have more than usual to work with ;-)

Thanks again for your interest and your efforts to pin down the ID of this moth. Steve Nanz writes on the larva post, "Zanclognatha marcidilinea or jacchusalis? I would have guessed Zanclognatha marcidilinea or possibly jacchusalis as my backup based on the adult. I've never tried to key out larvae but maybe you might want to try. See key to Zanclognatha from eastern North America (...). Z. jacchusalis might be more likely in your area." I'm pretty busy getting ready for a move, but if I find the time I'll dive into the larval key Steve mentions. --J

Steve Nanz who now runs MPG is the BG editor who sorted out the Genus. I will call his attention to this one. He used to want us to just place to Genus and he went through every so often and placed them correctly. I am not sure how much time he has for that lately.
