Data from: Body size evolution in an old insect order: no evidence for Cope’s Rule in spite of fitness benefits of large size

John T. Waller & Erik I. Svensson
We integrate field data and phylogenetic comparative analyses to investigate causes of body size evolution and stasis in an old insect order: odonates (“dragonflies and damselflies”). Fossil evidence for “Cope's Rule” in odonates is weak or non-existent since the last major extinction event 65 million years ago, yet selection studies show consistent positive selection for increased body size among adults. In particular, we find that large males in natural populations of the banded demoiselle (Calopteryx...
