Species Account

Sutton & Beaumont, 1989: Locally widespread in the South of England (Skinner, 1984) this species is generally uncommon as far north as Yorkshire. Now recorded from VC61.

Argus 47, 2001-04:
VC65. High Batts, 13.7.1984 (SPW). NEW VICE-COUNTY RECORD.

2012 (CHF): Porritt found this species to be "not uncommon in well-wooded districts" but it must have become scarcer in the county as records were very low until the 1980s when it started to expand its range. Numbers are now doing well (90 records in 2011) and it can be found over much of the county though it is still uncommon in VC61. It can appear in good numbers in open wooded areas eg 32 at Ellington Banks on 19.7.2006.
