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 terrestris is still present in a pH of 5.4, Dendrobaena octaedra at a pH of 4.3 and some Megascolecidae are present in extremely acidic humic soils. Soil pH may also influence the numbers of worms that go into diapause. The more acidic the soil, the sooner worms go into diapause, and remain in diapause the longest time at a pH of 6.4.
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 ...
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]
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 ...
Close-up of the clitellum of a Lumbricus rubellus. The clitellum is a thickened glandular and non-segmented section of the body wall near the head in earthworms and leeches that secretes a viscid sac in which eggs are stored. [1] It is located near the anterior end of the body, between the fourteenth and seventeenth segments.

A. lumbricoides was originally called Lumbricus teres and was first described in detail by Edward Tyson in 1683. [8] The genus Ascaris was originally described as the genus for Ascaris lumbricoides by Carl Linnaeus in 1758. [9] The morphologically similar Ascaris suum was described from pigs by Johann August Ephraim Goeze in 1782. [9]
