New to me, that is; I had never seen one before. We found this one in heather near the Aamsveen, a peat bog in the East of The Netherlands.
It is actually a moth called clouded buff (Diacrisia sannio), roodbandbeer in Dutch. They like to hide in heather and flee just when you have a shot set up; they are a pain to photograph, but I got a good shot of one:
Olympus Stylus 1s, 300mm, ISO200, f5.6, 1/250s
As this things often go, we saw another one within days of having seen the first one, in another location entirely, the Buurserzand:
Olympus Stylus 1s, 300mm, ISO400, f5, 1/80s
Thanks for watching!
