[BACK TO LIST]
GRAYLING Hipparchia semele
Primarily a species of coastal sand hills, it also occurs on limestone around Morecambe Bay (SD47) and there are tenuous colonies at two isolated inland sites on salt flashes in Cheshire, near Northwich and Sandbach. I am a little uncertain about the inland records in Lancashire during the second period and suspect misidentification.
