Davey, P., 2009: A strongly migratory species headquartered south of 40°N that ranges from a near annual in southern England, to uncommon in northern Scotland, the larva feeding on hedge bedstraw (Galium mollugo), lady's bedstraw (Galium verum) and wild madder (Rubia peregrina).
In Dorset, the moth (the ultimate flying machine!) is an increasingly regular visitor. Individuals have been recorded in every month of the year, but those seen in the first half tend to be immigrants from abroad. Exceptionally, larvae may be found in mid-summer fully exposed and feeding on lady's bedstraw growing within dry unimproved short-turf grassland; 2003 was a particularly good season for larval records: Freshwater Bay, thirteen larvae on lady's bedstraw on 10 July 2003 (R Cook), and Badbury Rings, four larvae on lady's bedstraw on 9 July 2003 (P Davey). There is one record of a larva feeding on goosegrass (Galium aparine).
Adults seen in the second half of the year may be home-grown, but undoubtedly resident populations are augmented by further waves of immigrants from transient colonies in northern Europe, or from sources further south. Classic behaviour of the moth is to hover hummingbird-like whilst nectaring on flowers or to examine wall faces or rocks in sunshine by day, however, roughly ten per cent of all adult records relate to individuals attracted to moth traps. Increasingly, examples are being recorded during the winter and early spring months often from inside buildings in or emerging from a state of hibernation: Swanage, flying at 2:30pm in the pharmaceutical department of Leo's Superstores on 14 December 2004 (R Eden), Blandford Forum, inside a closed-down shop, alive and stuck between the window and the 'To Let' poster on 15 March 1997 (P Davey).
