Worms are not insects. Insects are in the Phylum Arthropoda, in the class Insecta. All Arthropoda have jointed body parts while Annelids are segmented but not jointed. Earthworms are in the class Oligochaeta (meaning they are segmented worms with only a few bristles). There is a bigger difference worms and Insects than between a Reptile and a Mammal.
Most earthworms native to North America are thought to be extinct. The two most common species of earthworms in the USA are the common earthworm (nightcrawler) and the red earthworm (Lumbricus rubellus). These earthworms were introduced from Europe during colonial times through soil in potted plants.
