Davey, P., 2009: An immigrant species observed in southern coastal counties of England, the larva feeding on various grass species. In Dorset, the moth was first seen in 1975 and has been recorded intermittently ever since, mostly in small numbers. Many of those observed are likely to be long-distance immigrants from Iberia and north Africa, particularly those seen in the first half of the year; examples seen later in the year following early influxes are suspected residents. For example, influxes in June 1996, June 2000 and June 2003 backtracked to Iberia and Morocco. Relatively high numbers of moths then appeared subsequently during September and October in each year, and in the cases of 1996 and 2000, westerly airflows limited opportunities for immigration. The final graphic shows dates on which moths were seen in 1992 (red) and in 2000 (brown), illustrating offset brood cycles in each year of approximately three months. The great winter immigration of 2004 yielded two examples, one on 12 February, the second on the following day.
