Field Notes
Description:
Lumbricus terrestris is a large reddish worm native to Europe, but now also widely distributed elsewhere around the world due to human introductions. In some areas where it has been introduced, some people consider it to be It is an anecic worm. That is, it forms temporary deep burrows and comes to the surface to feed, as opposed to burrowing through the soil for its food as most other earthworms do. An unusual habit of this species is to pull leaves into the mouth of its burrow where they partially decay before being eaten. While they generally feed on plant material, they have been observed feeding on dead insects and feces.
The potential life span of Lumbricus terrestris is unknown, though it has lived up to the age of 6 years in captivity. The most widely accepted approximation is around 4-8 years in the wild.
Habitat:
Semi rural.
Notes:
L. terrestris is considered invasive in the north central United States. L. terrestris does not do well in tilled fields because of a lack of nutrients, pesticide exposure, and physical injuries from farm equipment. The species, however, thrives in fence rows and woodlots and can lead to reductions in native herbaceous and tree regrowth.
