The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings.
22.
It is formed by the prothorax, mesothorax and metathorax and comprises the pleuron, a lateral sclerite of the thorax.
23.
In dragonflies and damselflies the mesothorax and metathorax are fused together to form the "'synthorax " '.
24.
During what is called the precopulatory phase, the male rubs the female s mesothorax with his first two pairs of legs.
25.
Because the mesothorax and metathorax hold the wings, they have a combined name called the pterothorax ( pteron = wing ).
26.
The most obvious is that the thorax is divided into three sections, the prothorax, the mesothorax, and the metathorax.
27.
Three segments make up the thorax : the mesothorax, metathorax and prothorax, as well as the exoskeletal plates that connect with these segments.
28.
The thorax is divided into the prothorax, mesothorax and metathorax; the dorsal side of the prothorax is a sclerotized shield, the pronotum.
29.
The mesothorax and metathorax each have a pleural suture ( mesopleural and metapleural sutures ) that runs from the wing base to the coxa of the leg.
30.
The ventral view or sternum follows the same convention, with the prosternum under the prothorax, the mesosternum under the mesothorax and the metasternum under the metathorax.
