Species Account

Sutton & Beaumont, 1989: This species is moderately common in the South of England (Skinner, 1984) but had only doubtfully been recorded in Porritt's list (1904). In 1978, therefore when several were found at light on Skipwith Common, it was counted as a new County record. There has since been an unconfirmed record (due to no specimen) from another site which would seem quite suitable for this insect.

Beaumont, 2002:
VC63. Hatfield Moor, 1.7.2000 (HEB, ASE). NEW VICE-COUNTY RECORD.
VC64. Selby, 22.6.1992 (Jackson, 1993a); Askham Bog, 9.7.1998 (ASE). NEW VICE-COUNTY RECORD.

Argus 52, 2006:
VC65. Thorpe Perrow arboretum, 16.6.2006 (CHF et al.). NEW VICE-COUNTY RECORD.

2012 (CHF): This species is doing well and there is now spread across all of central and eastern Yorkshire with records as far west as Calderdale. There has been an extension in range in some other parts of the country.
