An early Knot Grass

Despite the temperature dropping to -2 last night, I did get 7 macro moths in the garden trap. These included the first Shuttle-shaped Dart of the year, and also the moth photographed below, which I believe is a Knot Grass.

Is this quite early for a Knot Grass? 

In addition, there was a fairly faded pug on the outside of the trap. I know everyone loves trying to identify pugs, so I include a photo in case anyone fancies a stab at it!
