Species Account


Most records are of leaf mines.

Argus 47, 2001-04:
VC63. Potteric Carr NR, mines on grey alder in Sept. 2003, reared Feb. 2004 (RIH). NEW VICE-COUNTY RECORD.
VC64. Farnham Gravel Pits, mines 30.10.2003, moths reared (CHF). NEW COUNTY RECORD.

Argus 58, 2009:
VC65. Aldbrough St. Johns, mines on grey alder 5.11.2008, moths reared 26.2.2009 (CHF). NEW VICE-COUNTY RECORD.

Current status (HEB, 2011): Not recorded in Britain until 1928 and then found only in southern England. Recently it has extended its range, the first county records being at Potteric Carr (VC63) and Farnham Gravel Pits (VC64) in 2003. Likely to be found more widely wherever its host tree, the non-native grey alder, is planted.

Argus 69, 2013: Still local but now recorded more widely, the earlier VC61 record was overlooked.
VC61. Bracey Bridge, mines on grey alder 27.10.2005 (HEB); Newport, larval mines 20.10.2013; Cottingham larval mines, 16.11.2013 (ADN). NEW VICE-COUNTY RECORD.
