White

I think the nature police have banned us from calling these Cabbage Whites despite the fact that they'll still lay waste to your brassicas. This daft thing flew into our sun room and got himself into the venetian blind. I rescued him several times but he flew straight back in. When I got him out again I cupped him in my hand and settled him on a cushion so he could get his strength back. He kindly posed for a photo to repay me for my efforts. I took him out and hoped he'd settle on something green but he was gone in search of a cabbage or some curly kale.

I think it's a small white (focus stacked in camera).
