Insects are invertebrate animals that have an external exoskeleton, six legs, and three body parts. Over one million species of insects have been described world-wide; new species are still being discovered. Insects found in our forests and rangelands are important pollinators, help control vegetation, help decompose plants and animals, and provide food for wildlife. They also can kill and damage trees.

US Forest Service R&D studies and develops tools for managing non-native invasive insects as well as native insects that significantly affect the forests of the United States and the many different forest functions people value: clean air, water, timber, aesthetics, recreation and other non-forest product commodities.
