Scoring of wing wear of peacock butterflies in belgium 2009-2020. Link to original pictures and classification

We show per record the assigned classification of the wear. We classified the condition of wear of the upperwings in 12,425 butterflies according to four categories: (1) immaculate: fresh, or with at most one tiny scratch on the upper wings or one minor dent to the wing edges, (2) slightly worn: some scratches on the upper wing and/or small dents to the edges, (3) moderately worn: many scratches to the upper wing and/or dented edges, and (4) heavily worn: (parts with) colors faded and/or heavily dented edges. The categories were chosen to allow the distinction of recently emerged individuals in particular: there is “more wear” between categories 3 and 4 than between the first two. Persistent wear and abrasions with multiple impacts at several spots was given more weight in the classification than a single major incident that resulted in larger parts of the wing missing. Pictures were randomly sorted before being classified by Jos Van Kerckhoven, who worked from a series of reference examples.本数据集将为每条样本记录提供蝴蝶磨损程度的标注分类结果。本次研究针对12425只蝴蝶的上翅磨损状况，划分为以下四类：(1) 完好无缺：翅膀全新，或上翅仅带有至多一处细微划痕，或翅缘仅存在一处轻微凹痕；(2) 轻度磨损：上翅存在若干划痕，和/或翅缘带有少量凹痕；(3) 中度磨损：上翅存在大量划痕，和/或翅缘出现凹损；(4) 重度磨损：（部分区域）颜色褪去，和/或翅缘严重凹损。本次类别梯度的设定尤其旨在区分新近羽化的个体：类别3与4之间的磨损程度差异，大于前两类之间的差异。在本次分类流程中，相较于造成翅膀大面积缺损的单次严重损伤，多处受创引发的持续性磨损与擦伤将获得更高权重。分类工作由Jos Van Kerckhoven完成，其分类依据为一系列标准参照样本，且所有待分类图像在分类前均已完成随机排序。
