Mayflies (Ephemeroptera), dragonflies, damselflies (Odonata) and stoneflies (Plecoptera) are basal representatives of winged insects (Pterygota). Due to their aquatic larvae, these taxa are obligatorily bound to freshwater and thus ideal model organisms to describe the diversity of aquatic paleo-ecosystems. Our model groups are ideal ecological indicator organisms and frequently preserved in Baltic amber, which would make possible a better understanding of European aquatic ecosystems from Eocene to Miocene. Essential for characterising past eco-systems however is the taxonomical knowledge of the fossil species composition, enabling reliable conclusions on past living conditions and their changes in time. The main objective of this project is to critically evaluate taxonomic data on the diversity of mayflies, dragonflies, damselflies, and stoneflies in freshwater paleo-ecosystems of Europe from Eocene to Miocene. It is aimed (1) to reinvestigate all available data on the systematics and taxonomy of basal aquatic pterygotes from European eocene-micene amber and sedimentary deposits, (2) to describe new species from these different deposits hosted in several European museums, (3) to compare the fossil species composition with the extant fauna, and (4) to gain new insights into paleo-ecology, biogeography and diversity of basal winged insects.

蜉蝣目 (Ephemeroptera)、蜻蜓、豆娘 (Odonata) 和石蝇 (Plecoptera) 是有翅昆虫 (Pterygota) 的基础代表。由于它们的水生幼虫，这些类群必须与淡水结合，因此是描述水生古生态系统多样性的理想模式生物。我们的模型群体是理想的生态指示生物，经常保存在波罗的海琥珀中，这将使我们更好地了解从始新世到中新世的欧洲水生生态系统。然而，对于描述过去的生态系统特征至关重要的是化石物种组成的分类学知识，从而能够对过去的生活条件及其随时间的变化得出可靠的结论。 该项目的主要目标是严格评估始新世至中新世欧洲淡水古生态系统中蜉蝣、蜻蜓、豆娘和石蝇多样性的分类数据。其目的是：(1) 重新研究来自欧洲始新世-小生琥珀和沉积矿床的基础水生翼足动物的系统学和分类学的所有可用数据，(2) 描述来自几个欧洲博物馆收藏的这些不同矿床的新物种，(3) 将化石物种组成与现存动物区系进行比较，以及 (4) 获得对古生态、生物地理学和多样性的新见解 基生有翅昆虫。
