Species Account


Argus 47, 2004:
VC61. Kilnsea & Spurn, 72 between 11-31.8.2004 (BRS). NEW VICE-COUNTY RECORD.
VC63. Rossington, 30.7.2001, 22.6.2003 (RIH). NEW COUNTY RECORD.

Current status (HEB, 2011): The earliest record was from Rossington (VC63) in 2001 with further records in that vice-county since. However most subsequent county records have come from VC61, where it has been recorded quite commonly on occasions, these are likely to refer to immigrant moths.
