In the face of declining numbers of insects across the globe, scientists continue to expand our knowledge about invertebrate organisms and their biodiversity across the globe. Insects are the most abundant animals on planet Earth—they outweigh all humanity by a factor of 17. Their abundance, variety, and ubiquity mean insects play a foundational role in food webs and ecosystems, from the bees that pollinate the flowers of food crops to the termites that recycle dead trees. With insect populations dwindling worldwide, there are still new species being discovered.
