Thank you for posting!
Thank you for posting these great shots--and for the info too. I've only ever seen the adult moth before! :-)
When I was a kid, I used to scour every birch tree trunk in the neighbourhood for one of these--with no luck. I'm in London, Ontario where there aren't that many birch or aspen trees.
Easily my favourite Underwing.
