Argus 47, 2001-04:
VC64. Bishop Monkton, 29.5.2004 det. JCW (D&DB). NEW VICE-COUNTY RECORD.
Argus 54, 2007: First recorded in the county in 1991. Still very local but slowly moving north.
VC62. Kilburn, 24.5.2007 (JD). NEW VICE-COUNTY RECORD.
Argus 58, 2009: Still at a very low density in the county with no records from its old haunts in VC63. We do however now have records from all five VCs.
VC65. Hutton Conyers, 26.8.2009 (CHF). NEW VICE-COUNTY RECORD.
2012 (CHF): Since 2002 this species has spread further north with records in VC64 (2004), VC62 (2007) and VC65 (2009) but curiously the spread in range has coincided with a reduction in numbers and there were none reported in 2011. Perhaps few people are trapping in beech woods.
