The correct Answer is:
To differentiate male from female cockroaches, follow these steps: ### Step-by-Step Solution: 1. **Examine the Anal Styles**: - Male cockroaches possess anal styles, which are small structures at the end of their abdomen. - Female cockroaches do not have these anal styles. 2. **Observe the Abdomen Shape**: - The abdomen of male cockroaches is typically narrower and more elongated. - In contrast, female cockroaches have a broader and more rounded abdomen. 3. **Check for the Ovipositor**: - Female cockroaches have an ovipositor, which is a structure used for laying eggs. - Males do not have an ovipositor. 4. **Consider Other Features**: - While the shape and size of the body and wings are similar in both sexes, male cockroaches tend to have longer antennae compared to females. However, this feature may not be as reliable for differentiation. 5. **Summarize the Key Differences**: - **Male Cockroach**: Anal styles present, narrow abdomen, ovipositor absent. - **Female Cockroach**: Anal styles absent, broad abdomen, ovipositor present.
