|Acrolepia autumnitella? Newton Longville, 20th November|
Acrolepiopsis assectella looks similar, and is a similar size (my moth had a forewing length of about 5½mm). However, assectella is described as being greyish brown, and mine is quite coppery (especially the cilia). The guide also mentions that Acrolepia autumnitella has a scattering of white scales before the termen which can form white cross-lines, and it can have a short black streak at about four fifths: I think both of these are visible in the photo.
There's also Acrolepiopsis betulella which is even more similar, but that's only found far to the north.
Have I got it right?
