    Habitat

    Margins of ponds, lakes, slow-flowing rivers and streams, fens, marshes, swamps, wet meadows and in ditches, dune-slacks and saltmarshes. Has turned up in light traps on occasions quite some distance from suitable habitat.

    Finding the Moth

    Larva: in the stem, with no external signs of feeding during May and June.

    Adult: can be swept from amongst the foodplant, flies in the late afternoon, at night and comes to light. Occasionally wanders some distance from suitable habitat.

    Similar Species

    Variable in colour from ochreous white with slightly darker mottling to fuscous with little mottling. Darker forms can resemble the dark form of Monochroa lutulentella, which is larger with broader wings and the first four segments of the abdomen ochreous yellow above (fuscous in M. lucidella).
