Davey, P., 2009: A very local species in northern England, East Anglia and Wales, the larva has not been found in the wild. This species is considered to be an ecotype of the Small Square-spot2123 that is in the process of separation. The single-brooded and paler Fen Square-spot is on the wing during July, so between the two broods of the Small Square-spot. It is a resident of fen and marshland, and is reputed not to become active until late in the night. In Dorset, the moth has been recorded from a light trap run regularly in a garden less than a kilometre from mire habitat on Stoborough Heath. Trapping in other mire habitats elsewhere over the past fifteen years has failed to produce an example of this species: Stoborough, on 28 June, two on 4 July, two on 6 July, two on 19 July 1977, two on 26 June, 13 July 1978, 13 July, 15 July, 23 July 1979, and on 21 June 1983 (B Withers).
