Last autumn I collected some mined oak leaves from Radyr Golf Course and left them in the garden over the winter. A few Phyllonoryter quercifoliella emerged a couple of weeks ago, but I was rather more pleased today to arrive home from an Easter break and find two Phyllonorycter muelleriella had emerged in my absence.
This species is supposedly a moth of ancient oak woodland, but Jake and Mike trapped one at Coryton roundabout in 2009 and Dave reared some from mines collected at the same site. Radyr Golf Course is less than 2km from Coryton, so it remains to be seen whether this species occurs more widely in Glamorgan.
I'll try and get a photo tomorrow...it's a lovely moth.
