Guarino (October 15, 2018) report that “Insects around the world are in a crisis, according to a small but growing number of long-term studies showing dramatic declines in invertebrate populations.” Guarino adds that “an international team of biologists estimated that, in the past 35 years, the abundance of invertebrates such as beetles and bees had decreased by 45 percent.” Lister and Garcia (2018) report in the Proceedings of the National Academy of Sciences, a startling sharp decline of insect abundance extending throughout the world.
