Davey, P., 2009: A species restricted mainly to south-east Britain, the larva feeding in the inner stems of common reed (Phragmites australis). In Dorset, the moth is common within all the larger coastal reedbeds and at low density elsewhere along the coast where common reed grows on wet clay cliffs and landslip habitat. There is no evidence that the moth colonises common reed growing inland, however a number of records from a range of localities up to ten kilometres inland suggest occasional dispersal from coastal reedbed colonies.
