Wings, not webs: Certain bugs are the winners of urbanization, impacting cities' insect diversity

Cities are bursting with life, both human and animal. The smallest of them—insects, spiders and ants—are easily overlooked, but their presence—or absence—in cities has wide-reaching effects. Scientists in Austria have published a study in Frontiers in Ecology and Evolution, which found a correlation between the presence of arthropods—invertebrate animals with an exoskeleton; among them are bees, insects, and spiders—and level of urbanization.
