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

description: 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
 hindwings showed a strong relationship between these traits and perching
 and flying behavioral strategies. Divergence time estimation suggests the
 crown age of Odonata to be 290-325 Ma. Bayesian biogeographical
 evolutionary analysis of nine biogeographical realms provides a
 preliminary biogeographical history for odonates spanning 325 Ma. Key
 family-level splits occurred during the Jurassic and Cretaceous,
 paralleling the increasing isolation of landmasses and the poleward drift
 of the contemporary Australasian and Holarctic regions. Both behavioral
 and morphological adaptations likely facilitated the distributional
 success of select odonate lineages. This study lays the foundation for a
 revised classification of odonates and a more complete understanding of
 the influence of flight behavior and wing morphology in relation to
 evolutionary processes shaping past and current odonate diversity.
