灰蓝蝶Zizeeria maha（Kollar）（鳞翅目：灰蝶科）的形态异常已被成功地用作评估福岛第一核电站事故生物影响的环境指标。为了应对未来的核事故或其他人为和自然灾害，我们研究了日本西南部这种蝴蝶的形态异常率，并建立了灾前参考数据集。我们主要在2015年夏天从52个地方收集了蝴蝶样本，这些样本被分为与仙台、伊方或高滨核电站相关的三个区域组。异常率和翅膀颜色图案修改率的平均值为3.8%和0.8%，分别为地方，表明蝴蝶没有受到严重的人为压力。在所有采集的样本中，女性的异常率（7.4%）显著高于男性（2.8%）。我们没有发现任何显着的异常率或修改率与纬度，地面辐射剂量，或距离核电厂的相关性。基于Logistic回归分析，性别，年平均温度，月平均温度可能会影响形态异常，这表明可能直接和后生温度对形态建成的影响。这些数据可作为日本西南部未来发生核事故或其他人为或自然环境灾害的参考数据集。
Morphological abnormalities of the pale grass blue butterfly, Zizeeria maha (Kollar) (Lepidoptera: Lycaenidae), have been successfully used as an environmental indicator to assess the biological impacts of the Fukushima Daiichi Nuclear Power Plant accident. To prepare for future nuclear accidents or other human and natural disasters, we examined the morphological abnormality rate of this butterfly in southwestern Japan and built a pre-disaster reference data set. We collected butterfly samples, primarily in summer 2015 from 52 localities, which were categorized into three regional groups associated with the Sendai, Ikata, or Takahama Nuclear Power Plant. Mean values of the abnormality rate and the wing color pattern modification rate for localities were 3.8% and 0.8%, respectively, indicating that butterflies were not under severe anthropogenic stress. Using all collected samples, the abnormality rate of females (7.4%) was significantly higher than that of males (2.8%). We did not detect any significant correlations of the abnormality rate or modification rate with latitude, ground radiation dose, or distance from the nuclear power plants. Based on logistic regression analyses, sex, annual average temperature, and monthly average temperature might have influenced morphological abnormalities, suggesting possible direct and epigenetic temperature effects on morphogenesis. These data serve as a reference data set for future nuclear accidents or other artificial or natural environmental disasters in southwestern Japan.
