The antennae are short and bristle-like.

The mouthparts are slender, and there are esophagus and saliva ducts in the mouthparts, which belong to the stinging and sucking type. The chest includes the anterior, mid and posterior chests, with the anterior and mid chests being longer.

The abdomen of the cicada is long conical and has a total of 10 abdominal segments.

Habits of life:

The larvae of cicadas live in the soil and have a pair of strong digging forefeet. The sap of plant roots is sucked by the piercing and sucking mouthparts to weaken the tree, make the branches die, and affect the growth of the tree. Usually stay in the soil for a few years or even more than ten years, such as 3 years, 5 years, and 17 years, these numbers have one thing in common, they are all prime numbers.

This is because there are very few factors in prime numbers, and when they drill out of the soil, they can prevent them from drilling out with other cicadas and competing for territory and food. When it is about to be feathered, it burrows out of the surface at dusk and at night, climbs on a tree, and then grabs the bark of the tree to molt and feather. When a black crack appears on the back of a cicada pupa, the molting process begins.
