Also known as: Lumbricus terrestris

Quick Summary

A "night crawler" is a common term for an earthworm, particularly a large one found on the soil surface at night. Earthworms belong to the class Oligochaeta and are found in soils worldwide where moisture and organic content are sufficient.12

Earthworms play a crucial role in soil health by aerating it, improving drainage, and incorporating organic material. As they consume decaying plants and organisms, they ingest soil, which is then excreted, enriching the soil. This process is vital for nutrient cycling and soil fertility.23

Earthworms are hermaphroditic, meaning they possess both male and female reproductive organs, but they still require another earthworm for fertilization. They reproduce by laying eggs in cocoons deposited in the soil.2
