Dark Chestnut (Conistra ligula) is a species of moth in the Noctuidae family.
It is similar to the far more common Chestnut (Conistra vaccinii), but is usually darker (as it's name suggests) and has a more angular forewing.
The length of the forewings is 13–15 mm. It overwinters partially as an egg and partially as imago. Mainly females overwinter as imago.
The larvae feed on Salix, Quercus, Prunus spinosa and Crataegus. Later instars feed on various herbaceous plants, such as Rumex and Taraxacum officinale.
