The forked dagger moth, speared dagger moth, cherry dagger moth or dart dagger moth (Acronicta hasta) is a moth of the Noctuidae family. It is found in the eastern deciduous woodlands, ranging west across southern Saskatchewan and Alberta into central southern British Columbia, south to Tennessee, Wisconsin and Kansas. Acronicta furcifera was considered a separate species until 1998, but is now considered a synonym. The wingspan is 35–45 mm. Adults are on wing from April to September depending on the location. There are two or more generations per year in the south and one or two in the north.
