Anyone who has washed a car after a road trip knows that insects often don't survive their encounters with traffic. For many flying invertebrate populations, this is not a problem (at least in the conservation sense), since adults breed shortly after emerging from their larval form and have therefore already reproduced by the time they collide with vehicles. This is not true for longer-lived species such as beetles and dragonflies, however, which breed over an extended period of time. For populations of these animals, which may encounter many roads during their travels through the habitat, traffic could have a serious impact by reducing the number of individuals available to breed. read more
