Illinois.—In pine forest associes, in black oak forest on sand, in oak-hickory forest on clay, and in climax forest; it evidently moved into the pine associes nightly, great numbers of oöthecae were found under bark of pine logs, where, in October and November, hibernating nymphs were found (Strohecker, 1937). In nests of Vespula maculata (Balduf, 1936; McClure, 1936).
Missouri.—Usually in hollow trees, under loose bark, in woodpiles, and in cracks in rural buildings (Rau, 1940).
Michigan.—Common in oak-dune and beech-maple forests, under loose bark on dead trees and fallen logs, and under debris on forest floor (Hubbell, 1922). "A characteristic inhabitant of the low shrub-terrestrial and probably the terrestrial-hypogeic stratum." It occurred throughout the upland forests; groups were found established in and under logs 100 to 200 feet from the nearest forest (Cantrall, 1943).
Ontario.—Very abundant in rocky, sparsely-wooded country, where it occurred in rotten logs and under loose bark; on tree trunk at night on rocky island in lake (Walker, 1912).
Parcoblatta uhleriana
North Carolina.—Under pine straw on ground in woods (Brimley, 1908). Under bark of dead trees; 92 males attracted to lights (Rehn and Hebard, 1910).
Virginia.—Resting on woods foliage; at night on road (Rehn and Hebard, 1916).
Eastern and southeastern U.S.—Trapped in molasses-baited jars: in oak and pine woods, in heavy barrier-beach forest, in both scant and typical undergrowth on pine barrens, in heavy grassy undergrowth on pine barrens, on border of pine barrens, on edge of swamp, in heavy deciduous forest, in heavy oak woods, in upland oak and chestnut forest, in chestnut forest, in forested ravine, and on ridge with heavy oak, chestnut, and maple forest. Found under damp leaves on edge of forest, under bark of decayed chestnut log, inside decaying chestnut log with Cryptocercus punctulatus, under palmetto roots, under bark of pine stump, and in dry leaves under live oaks (Hebard, 1917).
Tennessee.—In traps baited with cornmeal or cantaloupe in maple-gum-oak forest in a mesic valley, and in a stand of oak on a dry ridge (Walker, 1957).
Indiana.—Beneath cover on slopes of high wooded hills. "This is essentially a forest-loving species; usually occurring beneath leaves and other debris on or along the borders of heavy hardwood timber." (Blatchley, 1920.)
