Hi Words, it is very worn so an accurate id is probably going to be immpossible. I went for Square spot rustic as they can be very variable (ask Dan Salter, he he!!

) and the time is right for them here.
As you are fairly near to me, another could be Ingrailed clay.
Geographical location can change exact id of species as we often get a second generation (usually much smaller) here in the South East whereas further North they will only have the one.
Hope this helps.
