I like to say it right at the beginning, I don’t put any money on a bet about the identification of this moth, but several online sources led to the conclusion that this is a Sad Underwing Moth. Yesterday evening, when I came back from a little trip with our dog, the moth used our front door as a sunny resting spot. The sun was already pretty low but there was no need to employ a speed light or any other artificial light source. The dark underwings are usually hidden beneath the camouflage of the forewings but this one had one side exposed to the light. The color version of the image is not bad but I really liked the graphic impact of this moth, hence the development as a black & white photo.
