What are the physical characteristics of the German Cockroach?

• A. 5-7 cm long, dark brown with no stripes
• B. 8-10 mm long, beige with one stripe
• C. 12-20mm long, light brown with two dark longitudinal stripes
• D. 15-25 mm long, black with three stripes

Answer: (C)

Recognize the typical physical traits used to identify the German cockroach: a small size, light brown color, and a distinctive two dark longitudinal stripes pattern on the pronotum behind the head. The description that matches this pattern is a length of about 12–20 mm, light brown in color, with two dark longitudinal stripes. That combination—size in the 12–20 mm range, pale brown hue, and two dark stripes on the pronotum—is the standard identifying feature for this species. The other descriptions misstate size, color, or stripe count (for example, one description suggests a much larger roach with no stripes, another is shorter with a single stripe, and another is larger with three stripes and a dark color), so they don’t fit the typical German cockroach profile.
