Broad-lined Catopyrrha
Erastria coloraria (Fabricius, 1798)
Insects

Habitat [-]
In New York, the only currently known population is a cluster of colonies in the Albany Pine Bush. However this species should be looked for at any habitat that has or recently had the Mottled Duskywing which uses the same foodplant (New Jersey Tea), has a similar phenology, and generally seems less likely to persist than the Broad-lined Catopyrrha. As this species declined and disappeared from the Northeast, the last few occurrences were mostly on inland pine barrens, but historically the species was not limited to such places. In adjacent states and provinces, habitats also include or included oak savannas, openings in oak woodland, trap rock glades, and serpentine barrens. The Broad-lined Catopyrrha might occur on alvars or even old fields that have an abundance of the foodplant.

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.
