In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
Earthworm cocoons from L. terrestris An earthworm cocoon from L. rubellus. Several common earthworm species are mostly parthenogenetic, meaning that growth and development of embryos happens without fertilization. Among lumbricid earthworms, parthenogenesis arose from sexual relatives many times. [35]

Lumbricus terrestris has several common names, including common earthworm, nightcrawler, and dew worm. It is strongly pigmented, brown-red dorsally, and ...
The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
Oligochaeta (/ ˌ ɒ l ɪ ɡ ə ˈ k iː t ə,-ɡ oʊ-/) [1] is a subclass of soft-bodied animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms.
Lumbricus herculeus and Lumbricus terrestris, widely spread invasive earthworms native to Europe. Invasive species of earthworms from the suborder Lumbricina have been expanding their range in North America. [1] Earthworms are considered one of the most abundant macroinvertebrates in the soil of ecosystems in temperate and tropical climates. [2]
