Which family has antennae that are clubbed and bend like a hook, and typically a fast flight?

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

Answer: (D)

The main idea being tested is recognizing distinctive physical traits and flight behavior to identify a butterfly family. The combination of a clubbed antenna, with a bend that forms a hook, and a fast, darting flight is characteristic of the skippers, family Hesperiidae. These moth- or butterfly-like insects have stout bodies and antennae that end in a thick club that curves into a hook, which sets them apart from other families. Their flight is typically quick, strong, and “skipping” in short bursts, often near the ground or through vegetation. Other families don’t match this exact combo as cleanly. For example, swallowtails often have long hindwing tails and a graceful, unhooked-club antenna appearance, while whites and sulfurs have simpler, less hooked antennae and a steadier direct flight. Brush-footed butterflies (Nymphalidae) encompass a wide range of shapes and behaviors, but their antennae aren’t defined by a hooked club in the same way.
