Red Earthworm

Lumbricus rubellus

Also known as Red Marsh Worm, Red Worm, Humus Worm, Leaf Worm

Red earthworms inhabit upper soil horizons and rich leaf litter, rapidly breaking down organic detritus into fertile humus. Dorsally iridescent with deep reddish-purple tones, these active epigeic burrowers quickly retreat beneath foliage when exposed to light. Their continuous feeding and casting enrich topsoil, driving nutrient cycling across gardens, forests, and damp pastures.

Responsible observation
  • Habitat Care: Maintain thick organic mulch layers to encourage active soil surface feeding.
  • Gentle Handling: Pick up gently with damp hands or a soft leaf to avoid drying out their skin.
  • Night Spotting: Scan garden beds after rain with a dim light to observe surface movement.
