蛾类是欧洲西北部和全球生物多样性的重要组成部分。例如，在荷兰，766种较大的蛾被认为是本地的。在荷兰，业余录音师对这一群体的兴趣正在迅速增长。这使得中央数据库中的记录数量大幅增加，从而可以更好、更精确地计算当地飞蛾的趋势。在我们的分析中，大约三分之一的物种正在减少，可能被列为受威胁物种。另一方面，一些物种正在大幅增加。所有物种的丰度都有显著下降的趋势。与此同时，由于气候条件的原因，这一趋势每年都有很大的波动。因此，我们得出结论，气候变化对我们的蛾类动物群产生了强烈的影响。普通物种的个体绝对数量下降了三分之一。我们认为这对植物生物多样性产生了负面影响。欧洲西北部需要更好地保护蛾类，这也表明许多鸟类、蝙蝠和其他种群都依赖蛾类（或其幼虫）作为主要食物来源。
Moths make up a significant part of the biodiversity both in northwestern Europe and globally. In the Netherlands for instance, 766 species of larger moths are considered native. The interest of amateur recorders in this group in the Netherlands is rapidly growing. This has led to a strong increase in the number of records in the central database, allowing better and more precise calculations on the local trends of moths. About one-third of the species in our analysis are decreasing and could be listed as threatened. On the other hand, some species are strongly increasing. All species together show a significant, declining, trend in abundance. At the same time there exist strong year to year fluctuations in this trend which are due to weather conditions. We conclude, therefore, that the changing climate is having a strong impact on our moth fauna. The absolute number of individuals of the common species has dropped by one-third. We argue that this had a negative impact on plant biodiversity. The need for better protection of moths in northwestern Europe is also implicated by the fact that many species of birds, bats and other groups depend on moths (or their larvae) as main food sources.
