Yesterday I went out searching for leaf-mines again and there are still plenty to be found even though leaf-fall is well under way. I went looking in particular for Ectoedemia argyropeza which is a late miner of aspen and managed to find one occupied mine on a fallen leaf at nearby Kingswood. There were plenty of seemingly vacated mines, some of them much smaller in size than the occupied one which made me wonder if the larva sometimes retreats into the leaf petiole (where it starts mining) if it is disturbed. Another search for the related Ectoedemia hannoverella on black poplar proved unproductive at a couple of sites near Grendon Underwood but, amongst others, I did find tenanted mines of Ectoedemia angulifasciella on dog rose and Stigmella roborella on oak.
