Davey, P., 2009: A widespread but sparsely distributed species in Britain, the larva feeding on the ripening seed capsules of bladder campion (Silene vulgaris) and sea campion (Silene uniflora). In Dorset, the moth always was rare. Any colonies that may have existed have long become extinct: Powerstock, (Dale), Sherborne, (Dale), Glanvilles Wootton, on 25 May 1815 (Dale), Portland, (Dale, N Richardson); Gussage St Michael, in 1877 (JHW), Cranborne, occasionally (F Fisher). The low density of bladder campion may well account for the absence of the moth inland, but the locally frequent sea campion in Poole Harbour, and along the Purbeck and west Dorset coasts could theoretically support colonies. Interestingly, the Netted Pug1823 shares the same foodplants as the Marbled Coronet, and although rare, still manages to hang on. It is recommended that County Council extend their 'verges of interest' to include roadside verges that support bladder campion, and suspend mowing of the verges until the larva stage has been completed, usually by the end of August. It is also recommended that this species be included in chalk grassland habitat management plans.

Southerly to south-easterly airflows were established on all the following dates, and immigration is suspected on each occasion: Scar Bank, nectaring at flowers on 9 June 1934 and 10 June 1934 (A Russell), Dorchester, 2 July 1993 (Mrs M Spencer), Southwell, 30 June 2006 (via PBO website), Portland, at MV on 10 June 2004 (M Cade), Iwerne Minster, at MV on 1 July 1961 (H Moore), Shapwick, 18 June 2007 (P Davey), Canford, at MV on 10 June 1957 (D Southwell), West Blagdon, 28 May 2004 (D Green).
