澳大利亚东部的bogong蛾在经历2017年的种群崩溃后，于今年春季出现了显著复苏1。通过公民科学平台iNaturalist的Bogong Watch项目记录的数据显示，这一飞蛾种群的数量正在大幅增长1。
Bogong蛾曾经数量庞大，每年夏季有多达40亿只迁徙至澳大利亚阿尔卑斯地区1。这一物种的规模之大曾在2000年悉尼奥运会闭幕式上得以展现1。然而，在1980年至2016年间，该种群经历了长期缓慢衰退，并在2017年夏季出现了崩溃性下跌1。生态学家Ken Green对bogong蛾的监测已超过40年，见证了这一时期的变化1。2017年至2019年期间的澳大利亚干旱被认为是种群大幅下降的主要原因，农药和城市光污染也对其产生了负面影响1。
此次种群的复苏具有重要的生态意义1。山地小袋鼠等依赖bogong蛾作为食物来源的濒危物种将因此获益，同时被这些飞蛾传粉的植物也将受到积极影响1。
Bogong moth populations across eastern Australia have experienced a significant resurgence this spring, marking a dramatic recovery following the species' catastrophic collapse in 2017.1 Data collected through the Bogong Watch project on the citizen science platform iNaturalist documents this substantial growth in moth numbers.1 The recovery carries positive implications for endangered species that depend on bogongs as a food source and for plants reliant on their pollination.1
The bogong moth's population history reveals both historical abundance and recent devastation.1 These insects once numbered in the billions, with up to 4 billion undertaking seasonal migrations to the Australian Alps during summer months.1 A massive swarm of the moths was notably visible at the closing ceremony of the 2000 Sydney Olympics.1 However, the species experienced a gradual decline between 1980 and 2016, followed by a catastrophic crash in the summer of 2017.1 Ecologist Ken Green has monitored bogong moths for over 40 years, documenting these population shifts.1 The 2017-2019 Australian drought is considered the primary driver of the population collapse, though pesticide use and urban light pollution also contributed to the species' decline.1 Among the endangered species threatened by bogong scarcity is the mountain pygmy possum, which relies on the moths as a crucial food source.1
