For the county, we have a total of 16 records from 12 sites. First recorded in 1883.
Most records are of leaf-mines.
Argus 58, 2009: This is only the second county record, the last from VC65 prior to 1886.
VC64. Baildon, mine on elm 25.9.2009 (DP). NEW VICE-COUNTY RECORD.
Argus 60, 2010: Only the second recent county occurrence, following a record from VC64 in 2009.
VC63. Levels Lane plantation, mine on elm 6.11.2010 (SRS). NEW VICE-COUNTY RECORD.
2013 (CHF): A rare species in the county and by far the rarest of the three elm-feeding Stigmella species. The mine is distinctive and rather compact. It starts as a strongly contorted gallery which zigzags backwards and forwards in "intestine-like" loops. This is unlike the early mine of Stigmella lemniscella which can be in concentric circles. The frass is reddish-brown and coiled in the central section, occupying the full width of the corridor. There may be more than one mine in a leaf.
