There is of course another species, E. argoteles. Separable from E. monodactyla by genitalia. However this is only known from one site in Suffolk (although it's likely to be a bit more widespread). I think it's safe to say yours is E. monodactyla.
Thanks for the ID Douglas, I had a look through the plume moths on UKmoths but I wasnt confident about making an ID.
