Davey, P., 2009: A transient resident on Tresco in the Isles of Scilly between 1956 and 1957, otherwise a rare immigrant, the larva feeding on evergreen oak (Quercus ilex), the shrub 'rock rose' (Cistus spp.), common myrtle (Myrtus communis) and strawberry tree (Arbutus unedo). The moth is resident in the Mediterranean zone of southern Europe where large swathes of evergreen forest carpet the region. In Dorset, thirty-four moths have been seen on or close within ten miles of the coast. Observations refer mainly to third brood individuals, a sprinkling of second broods and three first brood adults, including one in 2007 and one in 2008. A total of nine moths were seen in the exceptional migrant year of 2006. There is no evidence that the moth has ever bred in Dorset presumably due to the absence of many of its host foodplants, although evergreen oak woodland at Durlston, Canford Cliffs, Bournemouth and Highcliffe could potentially host a transient colony. A 'Blair's Mocha' trapped at Scar Bank on 3 August 1947 by A Russell, referred to within the Dorset Natural Society and Archaeological Society Proceedings Vol 69, page 132, and within the Russell collection in Dorset County Museum is, on inspection, the Clay Triple-lines.
