[2], L. terrestris is a deep-burrowing anecic earthworm,[3] that is, it builds deep vertical burrows and surfaces to feed, as opposed to burrowing through the soil for its food as endogeic species. Night crawlers create and maintain a duff-free, mid-summer condition indefinitely in hardwood forests by eating the leaf litter from the previous season. [1], The dew worm has a hydrostatic skeleton and moves by longitudinal and circular muscular contractions. Biology. A nightcrawler is a large, plump worm that is desirable for use both as fish bait and for feeding pet reptiles and birds. The relative size of the mate, the distance from the presumed mates, the chance of being dragged to the surface, and the size-related fecundity all tend to play key roles in the mating behavior of the nightcrawler.

Introduction The Common Earthworm, Lumbricus terrestris, is a terrestrial invertebrate found abundantly across the United States. In some areas, this is having a seriously adverse effect on the soil structure and quality. The earthworm, Lumbricus terrestris L., caches seeds of the agricultural weed Ambrosia trifida L. in its burrow, providing seeds with a protected overwintering site. L. terrestris is a detritovore that eats mainly dead leaves on the soil floor and A-horizon mineral soil. It is also used as the example earthworm for millions of biology students around the world, even in areas where the species does not exist. For example, through much of the unirrigated temperate areas of the world, the "common earthworm" is actually Aporrectodea (=Allolobophora) trapezoides, which in those areas is a similar size and dabk color to L. terrestris. The Night Crawler (Lumbricus terrestris) is a large worm, measuring up to 25 cm in length and up to 1 cm in diameter. [15][16] It thrives in fence rows and woodlots and can lead to reductions in native herbaceous and tree regrowth.[17][18]. However, this can not be the case, like L.
