The flying insects bear wings on

The correct answer is 2nd and 3rd thoracic segments

Explanation:

• Insects are members of the class Insecta, characterized by their segmented bodies, jointed appendages, and exoskeleton.
• The body of an insect is divided into three main segments: head, thorax, and abdomen.
• The thorax is the central segment of the body, and it plays a crucial role in locomotion as it supports both wings and legs in flying insects.
• Flying insects typically bear wings only on the 2nd and 3rd thoracic segments (mesothorax and metathorax).
• The mesothorax typically supports the forewings, while the metathorax supports the hindwings.
• These wings are crucial for flying and are supported by strong muscles within these thoracic segments.
• Examples include butterflies, bees, and dragonflies, where the wings are attached to the 2nd and 3rd thoracic segments.
