Species Account

Sutton & Beaumont, 1989: Since first being taken in Yorkshire in 1978 as larvae at Potteric Carr (Heppenstall, 1979), this oak feeding species has spread considerably in the County and now seems well established in many areas. There are a few older records but these are not substantiated and so have not been included below (that recorded on the Thorne Moors list (Skidmore et al., 1985) from 1969 has been found to be in error (M. Limbert pers. comm.)).

Argus 47, 2001-04:
VC65. High Batts, 1992 (JCW, SPW); Nosterfield NR, 28.7.2001 (CHF, JCW, SPW; Hutton Conyers, 9.8.2000, four in 2001, three in 2002 (CHF). NEW VICE-COUNTY RECORD.

2012 (CHF): The expansion to the north and west has continued and there have been records as far north as Tynemouth (2011). Although the range has altered, it remains uncommon and only seen in small numbers - the maximum ever trapped in one session is three. There was a significant decrease to only 16 records in 2011.
