Catches are still pretty dismal in my central Oxford garden but I did find this micro on the wall by the front door yesterday evening. After having scoured the Sterling & Parsons book the best match that I can come up with is Esperia Sulphurella though there are a few ID points which are troubling me: the leg colour is different from the book, there is a much larger thorn on the middle leg than the book and the antennae aren't in the classic pointing straight ahead resting position, nor are they they same colour. I don't know if there is some variability in these features with E. Sulphurella or if in fact this is another species altogether.
Someone on Bird Forum has suggested Psychoides filicivora which seems a much better match. Looking at photos of it on UK moths the legs and antennae match perfectly.
