You must be joking? :)
I saw a very similar moth submitted for ID to iNaturalist which had been photographed at Fundy National Park on May 3 of this year. I spent some time trying to ID it when it was first submitted but gave up. I see that it still hasn't been ID'd (see HERE).
Your submission here has prompted me to spend some more time searching. Followed a hunch and found it quite quickly this time.
What is it, Stu?
I know the species!
Quite different from the 'normal' morph and nowhere as common.
Thought it might be a challenge for 'newbies' (i.e., people who have < 50 years of moth ID'ing)
I must admit that I missed your cryptic hint to an ID.
I certainly missed that cryptic hint as well, Tony.
I'm just getting on here now...busy day away today. This is soooo beautiful. I will join Joanne in searching for it ...but not till morning. Has my interest up!! :)
see the EDIT beneath the image; or decode Stuart's "You must be Joking"
Stu's cryptic hint went totally over my head at first!
Sure looks like the Feralia major.
No joking around...lol
