It wasn't a total bust though. I had a quick look around the exterior light for any moths and found a rather large, bright orange one thrashing around in a spider's web. It managed to get itself free and settled above the light, staying still long enough for me to get a decent photo. Moths are not my strong point by any means and I did get rather excited by this new visitor as most of the species I see in our garden are variants of grey/brown. After a quick Google search, I was ever so slightly disappointed to discover that my orange moth is called an Orange Moth. Someone clearly ran out of ideas on that day at the office!
There are a few nooks and crannies in the exterior walls of our cottage which I inspected with a torch and found two False Widow spiders occupied with the remains of their prey. They are easily identified by the light brown legs and contrasting dark abdomen with white-ish markings. I've never noticed them in the garden before and I didn't realise quite how small they are. We do also have a resident Cupboard Spider living in the eaves of our porch. It has been there for a long time and only ventures out of its funnel-like web at night. It is extremely shiny and black with a very bulbous abdomen.
I stuck around outside until it was more or less completely dark but still didn't see any more bats. This was a shame as they are so wonderful to watch; they have such a distinct flying pattern and often I have felt them fly so close to me that I could hear the clicking of their sonar. Maybe I'll have more success another night.
