Which pair are visually similar among common roaches?

Explanation:
Two common roaches that look alike are the Asian and German cockroaches. They’re both small, light brown, and have a similar overall shape, so at a quick glance they can be easily confused. The practical way to tell them apart is by the pattern on the shield behind the head (the pronotum). German cockroaches have two dark parallel stripes on the pronotum, a distinctive mark that Asian cockroaches usually lack or show only faintly. Because they share size, color, and indoor-habitat preferences, their visual similarity is why this pair is considered the most closely resembling among common roaches.
