Davey, P., 2009: A rare immigrant species that has been seen on less than fifty occasions in Britain, and resident in the sub-tropics and the tropics, and a transitory resident across the Mediterranean region, the polyphagous larva feeding on various wild and cultivated herbaceous plants and vegetables, and a pest species on potato (Solanum tuberosum) and soybean. It has also been imported several times to the UK in the larval stage on chrysanthemums. In Dorset, the moth has been recorded at light on five occasions: Sherborne, in October 1969 (C Gibson), Portland, on 17 October 2007 (M Cade), Winterborne Whitechurch, on outside porch on 23 June 2006 (I Cuff), Studland, on 8 October 1969 (S Coxey), Highcliffe, on 21 and 27 August 1983 (E Wild). The sources for all but one of the above are likely to have been the central and western Mediterranean, however, in the case of the 2006 example, the only opportunity for immigration from this region was eleven days previously.
