When identifying an earthworm, look at the patterns on its clitellum. The fine details are not as important, or even as clear, as stepping back to observe the general patterns. For example, the number of segments from the peristomium to the clitellum and the number of segments which make up the clitellum are species-specific in earthworms.

"Invasive earthworms are a global problem and can cause considerable changes to ecosystems," says Mac Callaham, research ecologist with the U.S. Forest Service Southern Research. The study by Cormier & coll. (–) and Rudie, Wampler & coll.

The etymology reads: The species name ernstmayri is a patronym honoring the German-American ornithologist, systematist, and evolutionary thinker Ernst Mayr (–).

The Megascolecidae are a large family of earthworms which has native representatives in Australia, New Zealand, both Southeast and East Asia, and North most ancient lineages of the family show a Gondwanan distribution and have been used as evidence of continental s of the Pheretima group of genera (e.g.

Amynthas) are widely distributed around the tropics, much as some Class: Clitellata. Earthworms are the best known and, in many situations, the most important animals that live in soil. Over earthworm species have been described worldwide, and it is estimated that further surveys will reveal this number to be much larger (ReynoldsFragoso et al.

2) North America has many species of its own earthworms, but they are being almost totally ousted by. There are two genera of Lumbricid earthworms that are native to North America.

The family Lumbricidae includes most of the earthworms familiar to people in North America and Europe, including the red worm Eisenia fetida and the nightcrawler Lumbri. Thousands of years ago, glaciers that covered North America and reached as far south as present-day Illinois, Indiana and Ohio wiped out native earthworms.

Any native North American species of earthworms (in the family Megascolecidae) that may have been living in the region were extirpated when glacial ice sheets covered the Upper Midw to 14, years ago, leaving the glaciated areas of North America earthworm free.

Natural recolonization by earthworms happens very slowly, with. For instance, the night crawlers (Lumbricus terrestris) so prized by fisherman are native to Europe, not North America, and so are the several species of “red wigglers” so common to American gardens and compost bins.

In fact, about one-third of the more than earthworm species found from Canada to Mexico are aliens in America. The Megascolecidae are a large family of earthworms which has native representatives in Australia, New Zealand, both Southeast and East Asia, and North America.

Depending on the species, an adult earthworm can be from 10 mm ( in) long and 1 mm ( in) wide to 3 m ( ft) long and over 25 mm ( in) wide, but the typical Lumbricus terrestris grows to about mm (14 in) long.

Probably the longest worm on confirmed records is Amynthas mekongianus that extends up to 3 m (10 ft) in the mud along the banks of the 4, km (2, mi) Mekong River.

Both of them die once temps drop below 10 C / 50 F, so there is very little chance of them over-wintering in most areas, let alone thriving. earthworms. Up to date, forty five species of terrestrial earthworm are already known from Thailand, and mostly they belong to the genera Amynthas and Metaphire of the family Megascolecidae.
