Davey, P., 2009: A local double-brooded species restricted to southern England and south Wales, the larva feeding on oak (Quercus spp.). In Dorset, old records exist of from several localities on sandy soil. The False Mocha, like the Orange Upperwing2257, appears to favour coppiced oak and the stunted shrubby oaks that grow on open heathland. Both of these habitats have disappeared, oak coppicing has all but died out, and the coniferisation of heathland has removed much of the stunted oak that was once dominant with birch, and, like the Orange Upperwing2257, it is doubtful that the species still occurs in Dorset. Care is needed in identifying potential False Mocha as they resemble Jersey Mocha1678.1, and to a lesser extent Blair's Mocha1678, and superficially the Maidens Blush1680, which lacks the black-ringed pupils. 'False Mochas' recorded in Holt Wood on 26 July 1955 and at Tarrant Gunville on 3 August 1956 are excluded from the records below as the dates and habitats where they were found, suggest Maidens Blush rather than this species, and there are no voucher specimens. Records of potential resident individuals follow; all are from more than fifty years ago: Chamberlaynes, at light on 28 August 1927, 10 August 1929, 16 August 1929, 30 May 1931, 6 May 1935, 23 May 1937, 4 June 1937, 12 August 1937, 4 August 1938 (H Andrewes), Norden, by day on 1 June 1901 and on 28 July 1901 (Reverend E Bankes), Canford Magna, at MV light on 3 June 1955 (O Woodland), Canford Bottom, at light on 2 July 1916, larvae abundant on 30 September 1916 (W Parkinson Curtis). The light trap records below are suspected immigrants: Scar Bank, on 2 September 1945, 20 August 1950, 6 September 1951 (A Russell).
