I’m an expat from the States, currently working through the JET Program.
I just saw this moth outside my door this evening. Not knowing what it was, I was stunned to find your site through the new Google photo search! (I didn’t think it worked very well last time I tried…)
It may interest you to know that I live in Hachinohe-shi, Aomori-ken. It’s a rather remarkably hot and humid summer this year, perhaps making the perfect habitat for these moths up here. I don’t know anything about their usual range, though.
Thanks for your site, and good luck adding to your collection!
