This dataset contains the raw data of questionnaire named “Original data” under the file “Questionnaire_data__butterfly_wing_color_brightness_and_contrast.xlsx”, that is the responses of local Dai people to the twenty questions (Questions were indexed as the abbreviation of the categories from BK1 to AK5. See the second column on sheet“proportion”). Original data was used to do Kaiser-Meyer-Olkin (KMO) and Bartlett’s Test of Sphericity in SPSS 17.0, and Confirmatory factory analysis (CFA) in SPSS Amos Graphics (see supplementary materials in Yang et al, “Biased local ecological knowledge of butterfly diversity provided by the ethnic minority in Southwest China's biodiversity hotspot\"). The file named “butterfly_images.rar” is the digital images of butterfly which were used to measure the wingspan, wing color brightness and contrast. These data were devoted to analyses the divergency between the butterflies recognised or not by local Dai people stored in the xlsx file named “Wing colo...本数据集包含存储于文件"Questionnaire_data__butterfly_wing_color_brightness_and_contrast.xlsx"中名为"原始数据"的问卷原始数据，即当地傣族民众对20道问题的作答结果（问题以BK1至AK5的类别缩写进行编号，详见"proportion"工作表的第二列）。本研究使用该原始数据在SPSS 17.0中完成了Kaiser-Meyer-Olkin（KMO）检验与巴特利特球形检验，并借助SPSS Amos Graphics完成了确认性因子分析（原文此处存在拼写笔误，原词为factory，正确应为factor），相关分析细节参见Yang等人发表的论文《中国西南生物多样性热点地区少数民族提供的蝴蝶多样性局部生态知识偏差》中的补充材料。 名为"butterfly_images.rar"的文件为用于测量蝶翼展、翼色亮度与对比度的蝴蝶数码图像。本数据集相关数据被用于分析当地傣族民众识别与未识别的蝴蝶之间的差异，相关内容存储于名为"Wing colo..."的XLSX文件中。
