COVER A collection of insects from different orders, representing some of the diversity of species found in North America. A new synthesis of existing data indicates overall declines among terrestrial insect assemblages but increases among freshwater assemblages. To accommodate as many orders as possible, insect sizes are not shown to scale. See pages 368 and 417.
