While searching out Sycamore tarspot fungi on local Sycamore trees, I’ve also been keeping a look out for leafmines, specifically for the mines of the Barred Sycamore Pigmy moth, Stigmella speciosa. (You can see the very attractive adult moth on the UK Moths website by clicking here.)
Although I’ve found the tarspot fungi, in varying quantities, on almost every Sycamore tree I’ve seen, the leafmines, though supposedly common, are not so easily spotted. Despite checking over a hundred Sycamore trees now, I’ve only found Stigmella speciosa mines in one location, where there were just three mines within the limits of my visibility. Perhaps more will turn up as I continue my search for Sycamore tarspot.
