Yellow Underwing sp. onslaught

Each night when I have put out the trap in the last few weeks, I have been confronted with a large number of yellow underwings. The four common species are generally all present but the lumbering Large Yellow Underwing is in the vast majority with a maximum count of 31 on the 5/6th Sept. To show the variety in the colouration, I have prepared a couple of montages.

Large Yellow Underwing.
There have also been some virtually black ones but not got a good photo of one.
Not my favourite species !
