Woodwalton Fen SSSI & SAC TL232833 1993 (TW)
A declining species scarcely reported since the 1970’s. Historically, it was primarily
associated with short grassland at the edges of disused railway tracks and gravel pits, as
such it has probably suffered from scrub encroachment and other forms of succession to
ranker vegetation.

Restricted in Huntingdonshire to Holme Fen, presumably because of a lack of suitable basepoor
soils elsewhere in the county. It may be a recent colonist of the county (mechanism
unknown), having been recorded for the first time by MM in 1989. It appears to be doing well
and may be increasing in abundance within the Fen.
