Data of characteristics related to morphology, components and wettablity of the epidermis of a butterfly species

A comprehensive investigation was conducted to characterize the integumentary features of third-to-fifth instar Papilio polytes larvae, with systematic analysis encompassing three critical parameters: morphological architecture, biochemical composition, and surface wettability. Morphometric evaluation was performed through high-resolution scanning electron microscopy (SEM) to quantify ultrastructural details of the larval epidermis. Compositional profiling was achieved using Fourier-transform infrared (FTIR) spectroscopy in the mid-infrared range (4000-400 cm⁻¹), enabling precise identification of chitinous and proteinaceous components. Hydrophobic properties were quantitatively assessed through contact angle measurements employing a goniometer-based static sessile drop method, with subsequent surface energy calculations derived from Owens-Wendt approximation models.

本研究开展全面调查，对3至5龄玉带凤蝶（Papilio polytes）幼虫的体壁特征进行表征，系统分析涵盖三项核心参数：形态结构、生化组成与表面润湿性。通过高分辨率扫描电子显微镜（SEM）开展形态计量评估，以量化幼虫表皮的超微结构细节；采用中红外波段（4000~400 cm⁻¹）的傅里叶变换红外（FTIR）光谱进行组成分析，实现对几丁质与蛋白质类组分的精准鉴定；通过基于测角仪的静态悬滴法开展接触角测量，定量评估其疏水性能，并基于欧文-温特（Owens-Wendt）近似模型计算表面能。
