yes. insects have three body segments, a head, a thorax, and an abdomen.
Yes an insect does have a digestive system
Insects do not have flesh like humans do. Instead they have something called an exoskeleton, which is like an armor suit for their bodies.
spiracles
Both male and female cicadas have organs for hearing. A pair of large, mirror-like membranes, the tympana, receive the sound. The tympana are connected to an auditory organ by a short tendon. When a male sings, it creases the tympana so that it won't be deafened by its own noise.
no, spiders have abdomens
However, insects do not breathe through their mouths, nor do they have lungs. In fact, insects are equipped with tracheal tubes terminating in pores, called spiracles, running along their abdomens. Insect trachea, much like the structure inside a lung, branch off into smaller and smaller trachea, but end deep in the various tissues of the insect; here, oxygen and carbon dioxide are exchanged continually. Due in part to the largely-passive gas exchange, insects are unable to 'breathe' very fast. This limitation is probably one reason why insects remain relatively small. It is possible to protect some plants from pests by spraying them lightly with castor oil (for example) as the oil effectively blocks their spiracles, suffocating them.
It does breath like most things, but uses something similar to a oxygen tank on its back and a small mouth piece. All spiders can dive to depths of over 100 meters and are trained to weld in complete darkness. Some spiders in Australia are equipped with flippers, and are recruited by the Navy to disarm small pockets of gas formed on the bellies of whales.

spiracles
A campodeid is a member of the Campodeidae, a group of six-legged, eyeless insects with segmented abdomens.
Like all insects, mosquitoes do not have lungs but instead have small holes in their abdomens called spiracles. Oxygen enters through these.
I have a few indian stick bugs, and their abdomens are around 2 cm long, but their torsoes are around 3 cm. The whole bug itself is around 8 cm.
That is a stereotype
Insects have evolved to have one set of wings because it gives them an ability to fold them over their abdomens and function as a system of indirect flight muscles.
The peritoneum.
they beat there abdomens on a tree or rock (beating there abdomens means they go back and forth in a humping motion)
A group of people were doing abdominal exercises in the weight room the other day, presumably to strengthen and define their abdomens.
