Barrens Dagger Moth
Acronicta albarufa Grote, 1874

Habitat [-]
The documented habitats in New York are pitch pine (Pinus rigida) - scrub oak (Quercus ilicifolia) barrens including dwarf pine plains. Most habitats from Massachusetts to North Carolina are also dry sandy pine-oak scrub. However, there are obviously more specific needs since most of this type of habitat in most parts of the range is unoccupied. In Ontario, the habitat is oak woodland or perhaps degraded oak savanna. At least in the eastern part of the range, this species is seldom, if ever, persistent in habitat remnants less than 1,000 acres in size and most occurrences are two to ten times that size.

Associated Ecological Communities [-]
  • Pitch pine-oak forest
    A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.
  • Pitch pine-oak-heath woodland
    A pine barrens community that occurs on well-drained, infertile, sandy soils. The structure of this community is intermediate between a shrub-savanna and a woodland. Pitch pine and white oak are the most abundant trees.

Associated Species [-]
  • A Notodontid Moth (Heterocampa varia)
