Bird Dropping Moth
Cerma cora Hübner, 1818

Habitat [-]
In New York, this species inhabits pine barrens in the Albany Pine Bush. Habitats in New England also tend to be sandy and are sometimes pine barrens. The habitat for the historical Ithaca collections is unknown. While it is uncertain, the Horseheads, New York site was probably acid, shaly, ridgetop woods. In almost all parts of the range, this moth is much more localized and habitat-restricted than the local foodplant, which is usually Fire Cherry (Prunus pensylvanica) in New York and New England.

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-scrub oak barrens
    A shrub-savanna community that occurs on well-drained, sandy soils that have developed on sand dunes, glacial till, and outwash plains.
  • Sandstone pavement barrens
    An open canopy woodland that occurs on very shallow soils over sandstone bedrock; this community is best developed where the bedrock is nearly level, thus forming a pavement. The best developed examples are found on Potsdam Sandstone in Clinton County. Large examples often include wetlands, such as perched bogs and inland poor fens.
