An article from the BBC reports on the results of a survey of the population and distribution of 1500 Odonata species from all over the world. One in 10 species is threatened, or categorized as critically endangered, endangered, or vulnerable. Species most at risk tend to live in southeast Asia (full of islands that have endemic species) and Australia (being impacted by climate change).
Too little data exist to accurately assess the status of many species. We often feel that while our contributions are small, we hope that they lend something to the collective knowledge -- now or in the future-- that will help with conserving these fantastic insects.
