The underside looks obscured in this photo. I am not clear how many prolegs it has. a clear lateral view photo would be good. I hope you have it safely in captivity to rear to get an adult moth for ID. Can you get an ID for the plant it was on? Asteraceae?
We might be able to answer that question if we knew the species.sadly at this point, all we have is guess work and common sense. So go for it. Best wishes.
