Soaring systematics: An evaluation of biogeography and flight behavior in dragonflies and damselflies (Insecta: Odonata) using phylogenomics

Dragonflies and damselflies (Insecta: Odonata) are descended from what were most likely the first winged animals, which flew ~320 million years ago (Ma). They comprise ~6400 extant species distributed across all continents except Antarctica. Examination of long-standing hypotheses regarding the role of flight behavior and wing morphology in shaping the global distribution of odonates has been limited by spatial and taxonomic scope. Here we leverage mobilized trait and distribution data derived from specimens and literature combined with a uniquely comprehensive target-enriched phylogeny (~940 loci) covering all families and 67 % of recognized genera. Ancestral state reconstruction of flight behavior strategies (“flyer” vs. “percher”) suggests the odonate ancestor was a flyer, spending a majority of its time when active on the wing, with multiple independent transitions to percher. Several transitions back to the flyer behavior have also occurred. Aspect ratios for forewings and hindwing..., , # Dryad dataset
