Morley's Final Catalogue: Very rare, and now probably confined to Barton Mills. Kesgrave, a few larvae (Gr); Tuddenham (Garrett); Mildenhall, and specimens on the wing at Barton Mills (T. & J. Brown): ante 1890. Our sole later records are of two taken at Barton Mills in June 1896 by the late E.G.J. Sparke, and now ? in his coll. in Bury Museum; and one at Brandon, 5 July 1937 (Hawley).
Recent Suffolk Status: Records in recent years from the Ixworth area are known to originate from to a deliberate release, possibly around 2014.
In 2019 several were noted at Bixley Heath, Ipswich in June (origins unknown but most likely a deliberate release as not in typical habitat), one was light-trapped at Bawdsey Hall on 24 June (M.J. Deans) followed by another at Ipswich Golf Course, Purdis Farm on 10 July (N. Sherman). Increasing and spreading eastwards nationally so more records are expected in the near future.
Life history: Single-brooded in the summer.
Habitat: Damp areas including fens and marshes.
