Davey, P., 2009: A local wetland species found as far north as southern Scotland, the larva feeding inside the stems of reed-canary grass (Phalaris arundinacea) and reed sweet-grass (Glyceria maxima). In Dorset, the moth shares the same habitat and has a similar density to that of Small Clouded Brindle2331. It is therefore local and strictly associated with river, fen and marsh habitat, being found on most of the county's river systems plus all the county's harbours and lagoons. The following records refer to dispersed individuals: Portland, at MV light on 10 July 1999, 23 June 2003, 11 July 2004 (M Cade). The following examples were trapped on the coast at times of immigration: Ringstead, on 14 July 2003 (D Foot et al), St Albans Head, two on 7 August 1992 (P Davey), Durlston, on 26 June 2003 (P Davey).
