Species Account

2013 (CHF): This is by far the most easily-identified species of Stigmella on oak. It is quite local in the county and has only so far been found in the south. The mine is a long, slowly widening, slender corridor, with a characteristic sinuous course. The corridor is completely filled with coils of green frass which turn brown later. Fresh mines are the same colour as the leaf and may be hard to spot. When the larva vacates the mine it soon becomes green and easier to spot.
