Lumbricus terrestris is a large, reddish worm species thought to be native to Western Europe, now widely distributed around the world (along with several other lumbricids). In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
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]
Eisenia fetida (Savigny, 1826) with head regeneration, in an anterior direction, possible at each intersegmental level back to and including 23/24, while tails were regenerated at any levels behind 20/21; thus two worms may grow from one. [43] Lumbricus terrestris (Linnaeus, 1758) replacing anterior segments from as far back as 13/14 and 16/17 ...
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 ...
Di Long or Dilong extract (Chinese: 地龍散; pinyin: dìlóngsàn; Wade–Giles: ti-lung san; lit. 'earth-dragon/-worm powder') is a medicinal preparation based on abdominal extracts from the earthworm species Lumbricus rubellus used in traditional Chinese medicine (TCM) for a wide variety of disorders, from convulsions and fevers to rheumatoid arthritis and blood stasis syndromes.
Lumbricus rubellus is a species of earthworm that is related to Lumbricus terrestris. It is usually reddish brown or reddish violet, iridescent dorsally, and pale yellow ventrally. They are usually about 25 millimetres (0.98 in) to 105 millimetres (4.1 in) in length, with around 95–120 segments.
Larger earthworms such as the nightcrawler Lumbricus terrestris and L. rubellus and the Alabama (technically Asian) jumper, Amynthas agrestis, can be eaten by adult salamanders, which is beneficial for their populations, but they are too large for juvenile salamanders to consume, which leads to a net loss in salamander population.

Lumbricus castaneus varies from chesnut to violet brown; brown or yellow ventrally, and has an orange clitellum. They are usually about 30–70 mm long, and have around 82–100 segments. Lumbricus terrestris has several common names, including common earthworm, nightcrawler, and dew worm. It is strongly pigmented, brown-red dorsally, and ...
