Davey, P., 2009: A rare immigrant species that is recorded mainly from southern and western coastal counties, the larva feeds on the roots of corn and milo maize (Sorghum spp.) in the tropics and sub-tropics where it is likely to be continuously brooded. It is also a single-brooded resident in southern Europe where it overwinters between late autumn and early spring, the larva feeding in this more temperate region on detritus and decaying plant matter. In Dorset, prior to 2003, the moth had been recorded on nine occasions mostly from light traps, and always on or close to the coast.
The remarkable winter immigrations during February 2004 and again in January and February 2008 from the Sahara, yielded more than twenty individuals on both occasions. The moth may appear at any time of the year, but the winter months so far have produced the largest numbers across the county.
