Those concerned about endangered species of dragonflies often focus most of their attention to larval habitat and maintaining aquatic sites with suitable water quality. Research by a group of Czech scientists* challenges the
They studied the habitat of adult spotted darter dragonflies, Sympetrum depressiusculum, and found that the terrestrial habitat surrounding the aquatic site could influence whether the aquatic site was suitable or not. Dragonflies were only found in areas with dense vegetation and not found in agricultural areas that were actively managed and disturbed. The dragonflies were primarily found within one kilometer of the larval sites. Efforts at conservation may require terrestrial buffers adjacent to suitable aquatic habitat.
presumption that the dramatic decline in distribution and abundance of many dragonfly species in temperate climates since the second half of the 20th century is mainly a result of destruction of aquatic habitats, and that protection of these habitats should thus be the primary focus.*
