Which family is commonly known as Long-Horned Beetles?

• A. Long-Horned Beetles
• B. Leaf Beetles
• C. Fleas
• D. Crane Flies

Answer: (A)

Long antennae that are as long as or longer than the body define this group, giving them the name long-horned beetles. They belong to the beetle family Cerambycidae, a diverse group whose larvae are typically wood borers. This combination of the distinctive antennae and the wood-boring habit is what sets them apart from other insects.

Leaf beetles are a different family (Chrysomelidae) and normally don’t show the extreme antenna length. Fleas aren’t beetles at all—they’re wingless, laterally compressed parasites in a different order. Crane flies are true flies (order Diptera) with one pair of wings, not beetles. So the family most commonly known as Long-Horned Beetles is Cerambycidae.
