| There is a rather extensive membranous area separating the sterna of the mesothorax and the metathorax. |
| In Coleoptera it consists of a tense elastic membrane, which is quite covered by the mesothorax. |
| These are the mesothorax and the first eight abdominal segments. |
| Thysanoptera adults have paired spiracles on the pleura of the mesothorax and metathorax and on the first and eighth abdominal tergites. |
| The next segment is the mesothorax, which is immovably fused to the next thoracic segment. |
| Tufted is a classical Drosophila mutant characterized by a large number of ectopic mechanosensory bristles on the dorsal mesothorax. |
