No, all W. cultraria which show spots (they are not always present in this species) have the spot(s) on this position, i.e. on the discoidal vein of the forewing. This is entirely normal. But in your specimen both spots are present and they are much larger than usual.Hi, on whole Web there is no Watsonalla, with dark spots at this location.
So it’s a slightly unusual/aberrational form of a female Watsonalla cultraria.
