What is green earthworm?

Green earthworms, also known as Lumbricus rubellus, are a common species of earthworm found in Europe and North America. Their body color ranges from dark green to reddish-brown, and they have a shiny, smooth skin with no hair-like structures. These earthworms are typically 5-10 cm long and have a cylindrical body shape.

Green earthworms are often found in grassy areas, gardens, and agricultural fields. They are important decomposers, breaking down organic matter in the soil and enriching it with nutrients. They also help to improve soil structure by creating channels for air and water to flow, which improves plant growth.

These earthworms are hermaphrodites, meaning they have both male and female reproductive organs, and they can reproduce both sexually and asexually. They lay their eggs in cocoons, and the young hatch out as fully-formed earthworms.

Green earthworms are sensitive to environmental pollutants and can be used as bioindicators of soil health. Their abundance and diversity can be affected by human activities such as land use changes, pesticide exposure, and soil disturbance.

Overall, green earthworms play an important role in soil health and ecosystem functioning, making them a valuable component of many ecosystems.
