Earthworm (Lumbricus terrestris)Earthworms, members of the genus Lumbricus, are often thought of as the motivation for awakening birds and as the favored bait of the young angler. The night crawler (Lumbricus terrestris), introduced to North America by early European settlers, is an earthworm that ranges from 90 millimeters up to 300 millimeters in length and constructs burrows up to 2.5 meters (approximately 8 feet) in depth. |
