History
The first record of the smallest noctuid in the British Isles came in late July 1979 when one was recorded near Cardorchan Farm (VC73), followed by another in 1982 at Beeswing. It was 1992 before it appeared again, three being found at Bargaly Lodge (VC73).
 
Since 1997, with the advent of better field guides, it has been recorded more frequently, nearly annually, even at observers' homes where they live next to suitable habitat. There is just one record for Wigtownshire which occurred at Carsegowan Moss in 1999; most records emanating from VCs 72 and 73.
 
In early August 2010 at Perchhall Loch SSSI, near Lockerbie, no less than 62 were recorded from four traps set in a fen-type habitat with scattered bushes and trees.
 
Life cycle
One generation. Overwintering is unknown. Pupates from a cocoon hanging from a plant stem.
 
Larval foodplants
Unknown.
 
Identification
The two dark oblique cross-lines on the forewing with the outer one extending to the wing tip is diagnostic.
 
Habitat
As its name suggests, mostly a species of wetlands, including marshes, fens, swamps, bogs and boggy moorland. Larvae have not been found in the wild.
 
Recorders' notes
Lack of records suggest it is being overlooked because of its micro size.
