Biogeography and life history of relict dragonflies

In a project supported by funds from the National Geographic Society, my colleagues, students and I have been studying the dragonflies of the family Petaluridae. This is a small family, with 11 species found in Australia, New Zealand, Chile/Argentina, the US, Canada and Japan.
