Davey, P., 2009: A local wetland species in southern Britain, the larva feeding in the inner stems of jointed rush (Juncus articulatus), sharp-flowered rush (Juncus acutiflorus) and soft rush (Juncus effusus). In Dorset, the moth is common only very locally in marshy fields, flushed wet heaths, wet woodland rides and by ponds and lakes wherever its foodplants abound.
The species tends not to stray beyond the confines of its wetland habitat, but coastal records suggest occasional immigration, and were particularly prevalent during the heatwave of August 2003 that coincided with massive northward movements of wetland species from mainland Europe.
