Which specific earthworm classification is considered ideal for vermicomposting?

epigeic

The application of earthworms for waste management, termed vermicomposting, requires species specifically adapted to living and feeding on the surface layer of organic debris, rather than burrowing deep into the soil profile. This category of worm is classified as epigeic. While other types exist, such as anecic worms which create deep vertical burrows, the epigeic species thrive in the confined, nutrient-rich environment of a compost bin. The text specifically names the Red Wiggler (*Eisenia fetida*) and the European Night Crawler (*Lumbricus terrestris*) as the two most common and suitable choices globally for successfully executing this type of household or commercial decomposition work.
