Jack Pine Looper
Macaria marmorata (Ferguson, 1972)

Habitat [-]
The caterpillars are dependent on their food plant, jack pine (Pinus banksiana), which has a very limited distribution in the state. Adults have been captured in two jack pine dominant sandstone pavement barrens in New York. Both sites have thin soils, exposed bedrock, an ericaceous shrub layer, and small boggy wetlands scttered throughout.

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.

    * probable association but not confirmed
  • 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.

    * probable association but not confirmed
  • 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.

  • A Noctuid Moth (Zale largera)
