|Two Lunar Underwings and one Black Rustic. In my garden light trap on 16 September 2012.|
For this photo I have placed them on one of the pieces of bark I picked up in the woods specifically for moth photographs. The two on the right are the same rather variable species, Lunar Underwings, named for a small dark crescent mark in the centre of the underwing. I'll put a photo below. To check for its presence I had to stun one (chemically) and open its wings out. I don't intend to do that to this species more than this once, as they always lose a few wing scales. But I am pleased to say that when I do do it, they always fly away afterwards.
The greyish one is clearly marked, but I thought the brown one might be a different, similar species, so that was the one I checked. But the lunar mark was there, and now I know what forewing markings are critical for identification.
The Black Rustic is an easy one. There are no other British moths with a combination of that dark colour, the slight glossiness, and the light outline around the kidney-mark.
