Question

The hindwings in cockroach arise from

• A. metathorax
• B. mesothorax
• C. prothorax
• D. none of the above

Answer 1

The correct option is A metathorax


The thorax of the cockroach has three segments - prothorax, mesothorax and metathorax.

There are two pairs of wings in a cockroach that arise from the dorsal side of the thorax. The first pair of wings arise from the mesothorax and the second pair of wings arise from metathorax. The mesothoracic wings are called forewings and the metathoracic wings are called hind wings. The forewings do not help in flight but cover and protect the hindwings. The hind wings help in flight.
