Identification difficulty

Occurring in any suitable habitat but perhaps preferring damp and marshy places.

When to see it

South of Scotland, it is double-brooded, flying in May and June and again in August and September. In Scotland there is one generation, flying in July and August, when it is difficult to tell apart from the very similar and possibly conspecific, Fen Square-spot (D. florida).

Life History

Where there are two broods, the first generation generally produces larger moths. The larval foodplants are a range of herbaceous species.

UK Status

A common species throughout Britain. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

VC55 Status

Fairly common in Leicestershire and Rutland. L&R Moth Group status = A (common and resident)
