Which of the following are identifying characteristics of fleas beetle?

• A. Adults are 1-4 mm in length
• B. They are parasitic
• C. The larvae are wormlike, without legs and chewing mouthparts
• D. All of the above

Answer: (D)

Flea beetles are tiny plant-feeding beetles. The adults are very small, typically about 1 to 4 millimeters in length, which matches the size described. They feed on plant tissue, making them pests that live off living hosts—plants—so they’re described as parasitic on their hosts in the context of plant damage. The larvae of leaf beetles, including flea beetles, are typically wormlike and legless, with chewing mouthparts suited to feeding on plant material. Putting these pieces together, the traits listed all line up with flea beetles, so all of them together describe identifying characteristics of this group.
