I found this moth from the Owlet moths (Noctuidae) in the house: the Cabbage moth (Mamestra brassicae) [1].
It is a common moth in the Netherlands and is recognizable by the white ringed spot on the lower half of the wing and the white inner line with a distinct ‘W’-shape in the middle, at the end of the wing .
