Thorax

  • The head is connected with thorax by a short extension of prothorax called neck
  • It consists of three parts i.e. prothorax, mesothorax and metathorax.
  • Each thoracic segment consists of a pair of walking legs.
  • From the mesothorax, first pair of wings arises while metathorax gives rise to second pair of wings.
  • Forewings are called tegmina and are opaque dark and leathery 
  • Hindwings are transparent, membranous and are used in flight.
