Which pairing is correct regarding cockroach species and distinguishing feature?

• A. German cockroaches have two longitudinal bands on their thorax.
• B. American cockroaches have light markings on their wings.
• C. Australian cockroaches have two longitudinal bands on their thorax.
• D. Australian cockroaches have light markings on their wings.

Answer: (C)

Distinguishing cockroach species in the field relies on visible patterns on the thorax (the pronotum) and, to a lesser extent, wings. For Australian cockroaches, two longitudinal bands running along the thorax are a recognizable, lengthwise pattern used to identify them. This makes the pairing with two longitudinal bands on the thorax the correct match for Australian roaches.

The other options attribute that specific thoracic banding to German cockroaches or focus on wing markings, which are not the standard identifying features for those species in common pest-control references.
