History 1860-2010

McDiarmid (1866) in the Transactions states that William Lennon had been highly fortunate in finding three new moths for Scotland… a Great Prominent near Dalskairth (VC73). This record is additional to MOGBI. Douglas Robinson (1870-71) had found two pupae at the foot of oaks in September, 1870, on Almorness (VC73).

During the 1960s Pelham-Clinton had found it closeby at Palnackie and across the Urr Water at Rockcliffe (both VC73).
1976-77 saw five records from the Rothamsted station at Gatehouse of Fleet, with one other RIS record in 1991 at Mabie Forest. In between those years, 1982-84, there were ten records of it trapped on the Hensol Estate (VC73). From 1997-2000 there were fifty records from Cally Woods, since then just over twenty records from widespread sites in Kirkcudbrightshire, the only vice-county where it resides.
