Detailed explanation-1: -The epidermis is the top layer, and the dermis is the middle layer. The dermis exists between the epidermis and the hypodermis.

Detailed explanation-2: -The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.

Detailed explanation-3: -A simplified insect cuticle traditionally consists of three layers [1]: (i) epicuticle, (ii) exocuticle, and (iii) endocuticle. Epicuticle is the outermost layer that is usually thin and has a cement-like chitin-lacking structure [2].

Detailed explanation-4: -The layers of the epidermis include the stratum basale (the deepest portion of the epidermis), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum (the most superficial portion of the epidermis).

Detailed explanation-5: -Epicuticle is the outermost of layer of cuticle; it forms a continuous layer covering the complete cuticular surface. Whereas the region of the cuticle, located between epicuticle and the epidermal cell layer, is called procuticle; it constitutes the main part of the total cuticle.
