Earthworm vs. Nightcrawler: Know the Difference
By Dua Fatima & Shumaila Saeed || Published on May 16, 2024
Earthworms are soil-dwelling worms beneficial for aeration and composting, while nightcrawlers, a type of earthworm, are larger and favor cool, moist soil.
Key Differences
Earthworms, broadly referring to various species within the oligochaete class, are crucial for soil health, promoting aeration and nutrient cycling. Nightcrawlers, specifically Lumbricus terrestris, are known for their size and ability to burrow deeply, enhancing soil structure and fertility.

All earthworms contribute to breaking down organic matter, nightcrawlers are particularly noted for their surface night activity, dragging leaves into their burrows to feed. This behavior contrasts with other earthworms that might feed within the soil or on the surface without significant burrowing.
