Barrens dagger moth
Acronicta albarufa, the barrens dagger moth, is a nocturnal noctuid moth with a fragmented distribution across North America. Adults are typically 3.0–3.5 cm in length and active from June to August, with some populations producing a partial second brood. The species is strongly associated with oak and pine barren habitats, particularly pitch pine–bear oak communities in the Northeast and oak savannahs in the western and southern portions of its range. It is listed as a species of special concern in Connecticut and believed extirpated there.

Research indicates small population sizes are typical for this subspecies, with individuals exhibiting moderate daily movement distances. The subspecies exhibits thermoregulatory behaviors and seasonal activity patterns that have been subjects of dedicated study.
