Authority:(Vieweg, 1790)

Common in damp woodland and grassland, gardens and rough meadows throughout the British Isles, a species of conservation concern under the UK Biodiversity Action Plan. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 30-38 mm. A useful field mark is the very small black dot between the orbicular stigma and dorsum, but there is no reliable way to distinguish this species from Fen Square-spot D. florida, and the two taxa may best be considered conspecific. Larva feeds on various herbaceous plants, including Dandelion and Dock.
