Which species belongs to order Blattodea and has Simple metamorphosis?

• A. Paper Wasp
• B. Pennsylvania Wood Cockroach
• C. Sawfly
• D. Rice Weevil

Answer: (B)

Understanding how insects develop helps you identify both their classification and their life cycle. Simple metamorphosis, or incomplete metamorphosis, means the young (nymphs) look like smaller versions of the adults, with no pupal stage; they molt until reaching the adult form. Cockroaches are in Blattodea and display this pattern. The Pennsylvania Wood Cockroach is a cockroach, so it belongs to Blattodea, and it shows incomplete metamorphosis. The other options don’t fit: Paper Wasps and Sawflies undergo complete metamorphosis (egg, larva, pupa, adult), and Rice Weevils are beetles with complete metamorphosis.
