The uneven distribution of species diversity on earth, with mountainous regions housing half of the high species diversity areas, makes mountain ecosystems vital to biodiversity conservation. The Panorpidae are ecological indicators, ideal for studying the impact of climate change on potential insect distribution. This study examines the impact of environmental factors on the distribution of the Panorpidae and analyzes how their distribution has changed over three historical periods, the Last Interglacial (LIG), the Last Glacial Maximum (LGM), and Current. The MaxEnt model is used to predict the potential distribution area of Panorpidae based on global distribution data. The results show that precipitation and elevation are the primary factors affecting species richness, and the suitable areas for Panorpidae are distributed in southeastern North America, Europe, and southeastern Asia. Throughout the three historical periods, there was an initial increase followed by a decrease in the area of suitable habitats. During the LGM period, there was a maximum range of suitable habitats for cool-adapted insects, such as scorpionflies. Under the scenarios of global warming, the suitable habitats for Panorpidae would shrink, posing a challenge to the conservation of biodiversity. The study provides insights into the potential geographic range of Panorpidae and helps understand the impact of climate change on their distribution.
地球上物种多样性分布不均，山区涵盖了一半的高物种多样性地区，这使得山地生态系统对生物多样性保护至关重要。蝎蛉科是生态指示物种，是研究气候变化对潜在昆虫分布影响的理想对象。本研究考察了环境因素对蝎蛉科分布的影响，并分析了其分布在末次间冰期（LIG）、末次盛冰期（LGM）和当前这三个历史时期是如何变化的。利用最大熵模型（MaxEnt）基于全球分布数据预测蝎蛉科的潜在分布区域。结果表明，降水和海拔是影响物种丰富度的主要因素，蝎蛉科的适宜区域分布在北美东南部、欧洲和亚洲东南部。在这三个历史时期，适宜栖息地面积最初增加，随后减少。在末次盛冰期，适应凉爽环境的昆虫，如蝎蛉，有着最大范围的适宜栖息地。在全球变暖的情景下，蝎蛉科的适宜栖息地将会缩小，这对生物多样性保护构成挑战。该研究为蝎蛉科的潜在地理分布范围提供了见解，并有助于理解气候变化对其分布的影响。
