This is the possible Cochylis molliculana. Sorry about the poor photo, but daylight is short supply, and I'm reluctant to let it out of the tube in case I spend half the night chasing it round the house!
Having looked at it in a bit more detail this afternoon, the colouration of the head and thorax(orangey brown) ruled out both C atricapitana and C hybridella for me, which are dark and whitish respectively. That leaves C molliculana as the likely candidate unless I have gone badly off the rails!
Would be good to hear what you think Dave. Let me know if you want me to get the specimen to you.
