Origin of earthworm
Regional variation note
Because the worm often comes to the surface of the earth when the ground is cool or wet, it is also called a nightwalker in New England, a nightcrawler, chiefly in the Northern, North Midland, and Western U.S., and a dew worm, chiefly in the Inland North and Canada. It is also called a red worm in the North Central, South Midland, and Southern U.S.
