Davey, P., 2009: A local species in Britain, the larva feeding on common marsh-bedstraw (Galium palustre) and fen bedstraw (Galium uliginosum). In Dorset, the moth colonises three wetland habitat types where it tends to be at low density. Firstly: river valley habitat such as Milton-on Stour, Christchurch on the River Stour, Wool on the River Frome, Iwerne Minster on the River Iwerne, Trigon Ford on the River Piddle and Wareham Meadows. Secondly: inland mire or marsh habitat on sandy soil such as Stoborough Heath, Middlebere Heath and Studland Heath; thirdly estuarine marsh, coastal marsh or lagoon habitat such as is found at or near West Bexington, Radipole, Lodmoor, Arne Bay, Brownsea Island and Hengistbury Head.

The following were recorded from light traps in localities where the species tends not to occur and are thought to be dispersed individuals from core habitat in south-east England or immigrants from the Continent: Portland, on 9 August 2003 (M Cade), Puddletown, on 13 August 2003 (H Wood Homer), Woolland, on 6 August 2003 (P Benham), Trigon, on 11 August 2003 (C Manley). Many other wetland species appeared in unlikely localities across the county during the intense heatwave that afflicted western Europe during August 2003.
