Where is the episternum?
The episternum is divided by the anapleural suture into a dorsal and a ventral sclerite. The first one is called anepisternum or dorsal episternum and is placed between the anterior spiracle and the insertion of wing.
What is scutum in insect?
The scutum is the largest dorsal sclerite of the notum and is bounded posteriorly by the scutoscutellar suture, which divides the notum into the scutum and scutellum. The scutellum is generally smaller than the scutum. In Heteroptera it is a small triangular sclerite between the bases of the hemelytra.
What are the functions of sclerites and sutures?
Sclerites and Sutures of Head The head capsule is formed by the union of number of sclerites or cuticular plates or areas which are joined together by means of cuticular lines or ridges known as Sutures. These sutures provide mechanical support to the cranial wall.
What are tergites and Sternites?
Tergite: It is a sclerite (plates that form exoskeleton) present on dorsal side of an abdominal segment in an arthropod. Sternite: It is a chitinous plate present on the dorsal side of an abdominal segment in an arthropod.
What is tergum and sternum?
Tergum is the covering each segment of the cockroach on the dorsal side. Sternum: The sternum is the covering of each segment of the cockroach on the ventral side.

Insect head is a Anterior most part of insect body it is hard and highly sclerotized compact structure which consisting of six segments that are fused to form a head capsule.
What is the function of tergum?
They articulate with the back (tergum) and sides (pleura) of the thoracic segments via the axillae: complex, three-dimensional mechanisms of stiff and compliant cuticle through which the muscular forces of the thorax are transmitted to the wings and which control the relative movements of the wings’ basal components.
