Many vacated mines found in bramble leaves and only this one with a larva, although possibly dead, in the mine
No interactions present.
I thought there remained some difference of opinion as to whether S. aurella and S. splendidissimella were distinct species.
With that little group of Stigmella there does seem to be some "flexibility" as to what constitutes a good species (51 Stigmella fragariella seems to have gone, for example): however, with the 2 in question a quick trawl through Fauna Europaea, the Dutch microleps site and Willem Ellis' Dutch leafminers site suggest that they are distinct. The genus is the focus of some DNA work which might show a different outcome.
The main problem with these two species is that they are essentially impossible to seperate on the basis of most mines as there is much overlap in terms of mine morphology.
