Which feature is characteristic of leaf beetles (Chrysomelidae)?

Explanation:
Leaf beetles are typically identified by their relatively short antennae, about half as long as the body. This length helps distinguish them from other beetle groups that have much longer antennae. They are generally able to fly and are not wingless, so that feature isn’t characteristic. The shape of the eyes isn’t a defining trait for this family, so the square-eyed appearance isn’t a good identifier either. In short, the antenna length—about half the body length—is the best clue for leaf beetles.
