A Noctuid Moth
Chytonix sensilis Grote, 1881

Habitat [-]
This species is typically confined to xeric (dry) sites. It is known from pitch pine-scrub oak barrens at Albany and Long Island and sandstone pavement barrens in Clinton County. The habitats are similar elsewhere in the range and are usually on sand, but they occasionally occur on acid rocks like granite. Many apparently suitable habitats lack this species. Populations may increase a few years after fires, but they can persist at low density for decades without fire. Populations of Chytonix ruperti, which may be the same species, are more predictably present in suitable habitats with sandy oak openings, oak woodland, oak savanna, or dunes near the Great Lakes.

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.
