This was fun to identify … well after dark last night, with all the windows and doors closed, a large (3cm+) moth was caught in the house. Taken outside it sat still just long enough for its portrait to be taken … not as sharp as I would have liked, tungsten light, after dark, ISO6400 and a long exposure hand-held … but you do what you can.
Anyway … obviously one of the “Underwings” so I started with the Catocala species but as you see from the photo, mine has but a single black band on the underwing while they all appear to have two … so what is it? Took a bit of reading, but I have it pinned down at last. It’s actually quite a common moth in the north-east of the continent by name of the Large yellow Underwing (Noctua pronuba) whose larvae eat grasses and low green plants of all sorts. Once again, it’s another European introduction that makes a good living here.
** There is quite a strong colour cast in the originals due to the tungsten lighting … I have added an edited version of the image at the end that is closer to the real colours
