Road mortality of vertebrates has been well researched, but road mortality of invertebrates has seldom been investigated in management conditions. Northern Michigan locate an vast coastal wetland called Mackinac Bay. A two-lane paved highway bordered to it to keep apart the marsh. In there, dragonflies breed and build their own homeland to defend territories. In the middle of 1997summer, people collected dragonfly corpses from the road so that daily mortality rates and sex ratios were estimated by road edge. Daily mortality varies so much from 10 to 256 casualties per kilometer. male-skewed was taken the most ratios of sex for all these casualties, normally 60% or higher. Differences for the history of life between the sexes present a stingy explanation for male specific mortality. Some species have more female mortality. It is needed to conduct more research about the effects of roads on dragonflies. Because dragonfly has a small populations when compared with other invertebrates. Moreover, it is restricted to wetland conditions where had been destroyed for many regions.
