Flame-shouldered Dart

Looks like we were thinking the same :)

The suggestion is my best guess. It is in your range and there is a worn sample in the reference link that is very similar to yours.

Thanks for the help, gatorfellows! I spotted this before, though it was much, much larger, and had more visible markings. What do you think?

Thanks Gators! I was quite unsure of this one. Thanks for the help!

Euxoa obeliscoides has a lot more marking. Even if it is worn, does not look right to me. This moth has a distinctive two tone cape - rust front, then brown and tip rust again. I will go hunting and see if I can help you find a better match.

Euxoa obeliscoides?
