朱砂叶螨的表皮由上表皮、外表皮、内表皮和皮细胞层组成，上表皮由里向外可分为电子致密层、角质精层、蜡层和护蜡层，厚度为０．０５３μｍ；原表皮分为外表皮和内表皮两层，外表皮厚０．１４５μｍ，内表皮厚０．６８４μｍ；外表皮向外延伸形成脊和叶，脊高０．８１５μｍ，宽０．１０５μｍ，脊距１．１０５μｍ；皮细胞层平均厚度为０．７９３μｍ。蜕皮时，首先上表皮物质沉积，形成片层结构；然后皮细胞分化，脊状突起渐出现；之后，皮细胞物质积累，脊状突起显著；最后，内表皮渐渐蜕去，被溶解。
The dermis of Tetranychus cinnabarinus is composed of upper epidermis, outer epidermis, inner epidermis and dermal cell layer. The upper epidermis is divided into inner and outer electron dense layer, keratin layer, wax layer and paraffin layer with the thickness of 0.053μm. The epidermis was divided into two layers, the outer epidermis and the inner epidermis. The thickness of epidermis was 0.145μm and the thickness of inner epidermis was 0.684μm. The epidermis extended outward to form ridges and leaves with ridge height 0.815μm, width 0.105μm and ridge 1 .105μm; average thickness of dermal layer was 0.793μm. When the skin molt, the first epidermal material deposition, the formation of lamellar structure; then the skin cells differentiate, gradually emerged ridge; later, the accumulation of skin cells, prominent ridge; Finally, the inner epidermis gradually shed, was dissolved.
