Observations: The incidence of the melanic form f. monacharia appears to vary considerably between localities. In the 1990’s at Fineshade this form constituted some 3% of the population, whereas in Geddington Chase the figure was around 20%. The moth was very common in the 1970’s in Grafton Park Wood at actinic light traps left overnight in an oak wood with many moths at rest on the tree trunks in the morning. In the early season of 2005 a moth was taken in the Pitsford Reservoir light traps on 25 November 2004 followed by others in December.
