Periplaneta fuliginosa, known as the smoky brown cockroach, thrives in warm, humid environments. It has a glossy, dark brown exoskeleton and is adept at flying. This nocturnal insect is notable for its attraction to light and its preference for outdoor habitats, where it plays a role in decomposing organic matter.

Periplaneta fuliginosa, commonly known as the smokybrown cockroach, is native to Asia, particularly in the tropical and subtropical regions. It has since spread to various parts of the world, including North America, where it is especially prevalent in the southeastern United States.

This species thrives in warm and humid environments. It is often found outdoors in areas with ample moisture and shade, such as gardens, leaf litter, and under bark or mulch. In urban settings, it can inhabit attics, basements, and crawl spaces where conditions are conducive.

The smokybrown cockroach is primarily a scavenger, feeding on a wide range of organic materials. It plays a role in the ecosystem by breaking down decaying organic matter. In its native and introduced ranges, it has adapted to both natural and human-associated environments, often taking advantage of sheltered, moist areas to thrive.
