Definitely some sort of pug moth.
Possibly a common pug? http://www.hantsmoths.org.uk/species/1834.php
Many thanks for your reply.
I agree its a pug moth but have been having problems trying to identify which one, because it has quite a distinctive dark central spot on its wings and a dark band on its abdomen and the moth is a bit worn I am still not sure. I expect I will catch another one of these moths soon and will examine it carefully against your suggestion of a common pug.
Once again thanks for your comments.
I had a look at this yesterday for a bit, and it is just not quite right for Common for me, but pugs are notoriously difficult to ID, even from looking at the individual.
For me, I think Freyer's Pug fits best markings wise, however although I get a few here, ours are generally not so grey and are a more tan coloration. I can't tell you how many times I've done this with pugs here, give me a Lime Speck Pug any day of the week.
