Davey, P., 2009: A scarce immigrant species, resident in the tropics and sub-tropics and a transitory resident to southern Europe, recorded mainly from southern counties of England and Wales, the polyphagous larva feeding on a wide range of plants. In the sub-tropics it is probably continuously brooded, and immigrants to the Mediterranean region in the spring spawn further broods that increase in size and expand northwards through the year. In Dorset, the moth visits the county irregularly and usually as singletons. Two generations are suggested by the data, with the peak of the second seven times larger, on average than that of the first. In June 1996, the notable influx of immigrant species from north Africa and the western Mediterranean discussed in the account of the Small Mottled Willow2385, produced a handful of Ni moths. A further wave of immigrants occurred during the second week of August, but small numbers were also trapped between late July and early September, regardless of weather type, suggesting a resident status for some in that year. There is a single record of larvae being found in the wild in Dorset, by Mrs N Richardson on rock samphire (Crithmum maritimum) on Portland; adults emerged on 6 and 10 September 1894, respectively. The great winter immigration of 2004 included this species: Cogden Beach, on 13 February 2004 (M Parsons, M Forster), Weymouth, on 12 February 2004 (Dr P Sterling), Portland, three on 11 February 2004, 12 February 2004 (M Cade), Durlston, on 12 February 2004 (S Nash).
