|Mine of Stigmella luteella on Birch, Westcott 1st November|
The other was a vacated mine on a fallen leaf of Norway Maple Acer platanoides. This can only be Stigmella aceris, which is an excellent discovery here. Back in 2012 I found a single mine on a Norway Maple in Upper Winchendon, just a few miles away, but that and today's find are the only Bucks records that I know of away from the Chilterns where the majority have been found on Field Maple Acer campestre. Not at all a common species in the county.
