Returning from a successful Ring-billed Gull twitch at lunchtime I was surprised to find this moth on my office wall. Presumably it had been lured there by the uplights, and I'll need to keep an eye out here apparently. This is also the site of my only encounter with a Vapourer, so apparently I now have an office 'list'!
(Initially I thought this looked like a Peppered Moth, but apart from anything else it's far too small. Then I had it as possibly a Spring Usher, before its true identity was revealed to me)
