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.
Some insects have adopted the worm name including inchworms, glowworms and silkworms, but they do not have the characteristics of an actual worm. A commonly known worm is the earthworm, which is found in gardens and most backyards. Its tubular body and lack of legs, antennae or proper body segments is descriptive of all types of worms, although some worms do have mouths.
