Which family often has patterns that resemble unpalatable species and includes yellow and black coloration?

• A. Nymphalidae
• B. Papilionidae
• C. Pieridae
• D. Sesiidae

Answer: (B)

Patterns that mimic unpalatable species rely on mimicry: predators learn to avoid colors and shapes that signal a bad taste or danger, so some butterflies copy those warning patterns to gain protection. Among butterfly families, swallowtails (Papilionidae) are especially known for bold, high-contrast wing patterns, including yellow and black bands or patches. This striking yellow-and-black appearance is a common trait in many Papilionidae species, and they frequently participate in mimicry relationships with distasteful species. That combination—mimicry of unpalatable models and prominent yellow-and-black coloration—makes this family the best fit.
