Seventeen native species and 13 introduced species (from Europe) occur in the eastern United States, L. terrestris being the most common. Earthworms occur in virtually all soils of the world in which the moisture and organic content are sufficient to sustain them. One of the most detailed studies of earthworm activities was conducted by English naturalist Charles Darwin.

How do earthworms reproduce?
Earthworms are hermaphroditic; i.e., functional reproductive organs of both sexes occur in the same individual. The eggs of one individual , however, are fertilized by the sperm of another individual. During mating two earthworms are bound together by a sticky mucus while each transfers sperm to the other. The worms separate and form cocoons; the cocoon moves forward, picking up eggs at the 14th segment; at the 9th and 10th segments it picks up the sperm deposited by the other earthworm. The cocoon slides over the head, and fertilization takes place. Within 24 hours after the worms mate, the cocoon is deposited in the soil.

How many species of earthworms are there in the world?
There are known to be 27 species of earthworm in the United Kingdom, and 182 in North America. Of all of the earthworms known in North America, over 30 percent of them are introduced. This means they are not native species, and have found their way into the continent, usually by the importing and exporting of plants or sale of worms for fishing bait. The introduction of non-native worms is actually a huge problem, as these worms become invasive and can threaten the balance of natural ecosystems. Native worms, on the other hand, are enormously advantageous to our ecosystem and offer numerous benefits to our soils and plants.
How do earthworms help soil?

Also known as the ‘dew worm,’ or ‘lob worm,’ this is a species of earthworm that is native to Western Europe, though as a result of transporting plants and worms for fish bait, this worm is now commonly found across North and South America, Asia, Africa, and Oceania. It is an invasive species, feeding on piles of leaves on the soil’s surface and the top layers of the soil itself. They have strong muscles that enable them to move quickly from known predators such as foxes, shrews, and birds. They are darker at one end, with a red-brown pigmentation. They can most often be seen during wet weather, and during dry seasons may burrow in the top layers of soil for protection from both heat and predators.
