Davey, P., 2009: A local species in southern England found in large fens and marshes, the larva feeding on bulrush (Typha latifolia). In Dorset, the moth is local and colonises nutrient-rich ponds, flooded pits and ditches, mainly in the Poole Basin, wherever bulrush is dominant. Adults fly around their watery habitats for an hour or so and later range more widely, with dispersal a relatively frequent occurrence across the county.
Conservation agencies managing sites containing bulrush-rich habitat, for example Stanpit (Christchurch Borough Council) or Norden (Dorset Wildlife Trust) should include this species in their management plans.
