Beaumont, 2002:
VC61. South Cave, 7.7.1994, gen. det. HEB (DBC). NEW COUNTY RECORD.

2013 (CHF): Identifying the oak-feeding Stigmella species (with the exception of basiguttella is fraught with danger and records are not acceptable without breeding out the adult moth. This is a rare species in the county with few records though it might be commoner than the dots on the map suggests. The egg can be laid on either side of the leaf. The mine is a long, slender, not very contorted corridor. In the first part the frass lies in a very narrow line; later the frass may in rare cases lie more widely scattered, but nowhere does it take more than 1/3 of the width of the gallery.
