Most records are of leaf mines.
Argus 60, 2010:
VC63. Sandall Beat Wood, mine on aspen 25.10.2010; Blaxton, mine 13.11.2010 (SRS). NEW COUNTY RECORD.
Current status (HEB, 2011): A mainly southern species, although there are Scottish records, and generally regarded as scarce. Found in Yorkshire at Sandall Beat Wood and near Finningley (VC63) in 2010.
2013 (CHF): This is the only species of Stigmella that mines on aspen so is unlikely to be confused with any other species. Since the first record in the county in 2010 it has been found more widely in the south east of VC63 and has now been found in VC61. The mine is a densely winding corridor, later sections are strongly widened, almost forming a secondary blotch. The frass is in a more or less continuous central band that even in the narrow initial part, never completely fills the corridor.
Argus 69, 2013:
VC61. Allerthorpe Common, mines on aspen 24.10.2013 (CHF). NEW VICE-COUNTY RECORD.
