Parcoblatta pennsylvanica, commonly known as the Pennsylvania wood cockroach, thrives in deciduous forests of North America. Males are capable fliers with elongated wings, while females are wingless. They are scavengers, feeding on organic matter, and play a vital role in nutrient cycling within their ecosystem.

Parcoblatta pennsylvanica, commonly known as the Pennsylvania wood cockroach, is native to North America. Its geographical distribution primarily includes the eastern and central United States, ranging from the Atlantic Coast westward to the Great Plains. It is notably found in states such as Pennsylvania, New York, Ohio, Indiana, and extending south to Georgia and Alabama.

This species typically inhabits deciduous forests and woodlands. It thrives in areas with abundant leaf litter and decaying wood, which provide shelter and food sources. The climate in these regions is generally temperate, with distinct seasonal variations including cold winters and warm summers.

Parcoblatta pennsylvanica occupies a niche as a decomposer, feeding on organic material such as decaying leaves and wood. This role is crucial in nutrient cycling within forest ecosystems. The species is adapted to living in moist environments, often found under logs, stones, and in other sheltered spots on the forest floor.
