A stem-relative of dragon- and damselflies, Brunellopteron norradi Béthoux, Deregnaucourt and Norrad gen. et spec. nov., is documented based on a specimen found at Robertson Point (Grand Lake, New Brunswick, Canada; Sunburry Creek Formation; early Moscovian, Pennsylvanian) and preserving the basal half of a hindwing. A comparative analysis of the evolution of wing venation in early odonates demonstrates that it belongs to a yet poorly documented subset of species. Specifically, it displays a MP+CuA fusion,...

Aim: Recent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large-scale, long-term changes for most insect groups but opportunistic citizen science data is widespread for some. Here, we took advantage of citizen science data to investigate distributional changes of Odonata. Location: Germany Methods: We compiled over 1 million occurrence records from different regional databases. We...
