Species Account


Sutton & Beaumont, 1989: Recognised as British in February 1984, some specimens were soon found in Yorkshire by H. E. Beaumont in July of the same year (Harrison & Sterling, 1986). Although there are as yet few confirmed records it is thought likely that this species is sympatric with its congener over most, if not all of its range. Some authorities are still not convinced by the separation and refuse to distinguish the two. The name of this species has just been revised from secalella (Remm) to didyma (Esper) (Lempke, 1988).

Beaumont, 2002:
VC61. South Cave, July 1992 gen. det. HEB (DBC); Rudston, presence confirmed by gen. det. (ASE).
VC62. Hutton Rudby, 23.6.1990 conf HEB (GWF). NEW VICE-COUNTY RECORD.
VC63. Rossington, presence confirmed (RIH); Wintersett Country Park, four 21.7-3.8.1998 gen. det. HEB (PSm, PM et. al.).
VC64. Malham Tarn, regularly during August 1991-1998 (DB).

Argus 58, 2009:
