Species Account


Sutton & Beaumont, 1989: This species seems to be at the limit of its north-eastern range in Yorkshire and currently seems to be in decline. There are only two recent sites, both in VC61 although there should be no shortage of suitable oak woods elsewhere in the County.

2012 (CHF): Local in small numbers in mature oak woodland in the centre of the county. Numbers are probably stable. Do not confuse this with Lunar Marbled Brown which flies earlier and is much more widespread in Yorkshire.
