I was chuffed to find this is the garden MV this morning, Lyonetia prunifoliella, which has an interesting history in the UK. Here's what the excellent UK Moths website says about it:
"Formerly locally resident in parts of southern and central England, this moth seemed to have died out as a British species, and had not been reliably encountered since around 1900. The first recent record appears to be in 2007, since when it has been encountered with increasing frequency in a number of counties including Dorset, Norfolk and on the Isle of Wight, Hampshire."
My photograph is not up to scratch, being taken under dark skies and a slight drizzle, and this moth is tiny. Still, it gets across the delicate markings that clinched the identification.
