Which family is characterized by ends of legs that are forked?

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

Answer: (A)

The feature being tested is how the ends of the legs appear when you look at butterflies, which can help distinguish families. In this family, the tips of the legs look forked because the final segments form two prongs that diverge. That forked appearance is a recognizable external cue you can spot on many specimens, making it a handy clue for identifying members of this group. In other families, the leg ends don’t show this forked tip in the same way. For example, some have forelegs that are reduced and not used for walking, or have different terminal limb shapes, so the forked look isn’t a common diagnostic trait there. So noticing the forked leg ends helps separate this family from the others.
