Which type of roach has black bars running lengthwise on its pronotum?

The German roach is identified by the distinct black longitudinal stripes running along the edges of its pronotum, which is the shield-like structure that covers its thorax. These stripes provide a key characteristic for identifying this species, especially when distinguishing it from other types of cockroaches. The coloration and patterning on the pronotum help in recognizing the German roach, which is one of the most common and problematic indoor pests. This visual identification is crucial for pest control operators, as it enables effective targeting and management strategies to eliminate these pests.
