Blaptica dubia, commonly known as the Dubia roach, inhabits tropical and subtropical regions of Central and South America. They are winged but rarely fly, preferring to scuttle and hide. Dubia roaches are nocturnal, feeding on decaying plant matter, and are known for their docility and low odor, making them ideal feeder insects for reptiles.

Blaptica dubia, commonly known as the Dubia roach, is native to Central and South America. Its geographical distribution includes countries such as Brazil, Argentina, and French Guiana.

The Dubia roach typically inhabits tropical and subtropical environments. These areas are characterized by warm temperatures and high humidity levels, often exceeding 80% relative humidity. The species is commonly found in forested regions where leaf litter and decaying organic matter provide essential cover and food resources.

Blaptica dubia occupies the ecological niche of a detritivore, feeding on decomposing plant material and other organic debris. This role is crucial in nutrient cycling within their native ecosystems. The species is also known for its ability to adapt to various microhabitats, including those found in human-altered environments, as long as warmth and moisture are sufficient.
