Madagascar has approximately 175 species of Odonata. Of the Anisoptera ca 60% is endemic and of the Zygoptera almost 95%. The endemic species can roughly be separated into ‘new endemics’ that are probably recent arrivals from the African mainland and ‘old endemics’. The latter group includes many members of the families Megapodagrionidae, Platycnemididae and Corduliidae,…
For the Odonata species known from islands in the western Indian Ocean – excluding Madagascar – comments on 33 species of conservation concern are given.
From eastern Africa, ranging from Somalia and Ethiopia south to Mozambique and Zimbabwe and west to eastern Democratic Republic of Congo and Botswana, ca 500 species of Odonata are known. Comments on species and sites of conservation concern are given as well as recommendations for future research and conservation activities. Due to the rapid and…
This report summarizes progress that has been made during the past five years toward the understanding of Neotropical Odonata. It also presents a list of critical species and sites, threats to Odonata conservation in the region, and priorities for further research. This region, the richest in the world for Odonata, must be a focus of…
Of the approximately 439 species of Odonata known from North America, north of Mexico, comments on 25 species (6%) of conservation concern are given. Species deemed to be under the most threat are Ischnura gemina, Gomphus sandrius, Ophiogompbus australis, Stylurus potulentus, and Libellula jesseana. Two other species not under threat, Neurocordulia micbaeli and Somatochlora brevicincta,…
The conservation status of Odonata in the South Pacific Region and in Australasia is reviewed. Australian and New Zealand faunas have recently been monographed, for the rest of the region lack of data is the major handicap to concrete planning. The taxonomic status of the different island faunas and the state of habitat modification on…
Ten species of Hawaiian Odonata are considered to be currently at risk, all of them zygopterans belonging to the endemic genus Megalagrion. These species and their proposed status are as follows: M. jugorum, endemic to Maui and Lanai [CR, possibly EX]; M. leptodemas, endemic to Oahu [CR]; M. molokaiense, endemic to Molokai [CE, possibly EX];…
The Australian Odonata fauna is reviewed. The state of the current taxonomy and ecology, studies on biodiversity, studies on larvae and the all identification keys are reported. The conservation status of the Australian odonates is evaluated and the endangered species identified. In addition the endemic species, species with unusual biology and species, not threatened yet,…

Progomphus obscurus is one of the most abundant dragonflies in South Carolina, USA. We collected dragonfly larvae from 127 sites in the Enoree River and nine of its tributaries, and correlated the abundance of P. obscurus larvae with physical and chemical characteristics of these streams. As expected for this burrowing species, larval abundance varied among…
