Worm species for worm composting

What are the different worm species used for worm composting?

We obviously use species adapted to our climatic conditions.
Species used in Western Europe for example (mainly E. Fetida, E. Andrei) are endemic and adapted to the temperate climate. Worms used in warmer areas are different …

Let’s look at the big species used in the world.

Eisenia Fetida

Red Wiggler or Tiger worm

Eisenia Andrei

Red Tiger Worm
Eiseinia Fetida and Eisenia Andrei are the most common worms for vermicomposting in Europe and temperate regions.
These 2 species are very close and live in similar conditions.

Worms can live between 1 ° C and 33 ° C. The optimal temperature is between 15 ° and 25 ° C.
The size of the adults is about 50 to 70 mm. They breed relatively quickly.
Both species are quite difficult to distinguish.

Eisenia Hortensis / Dendrobaena Veneta

European Nightcrawlers / European Red Worm
Eisenia Hortensis is also sometimes called Dendrobaena Veneta.

He can live in wider climatic conditions (he supports heat better).

Compared to Eisenia Fetida and Andrei: it is bigger, but reproduces less quickly.

It lives in conditions similar to E. Fetida, but supports better the acidity and the high temperatures.

Its adult size is about 120 to 170 mm.

It has a somewhat runaway behavior when introduced into wormcomposters.

Eudrillus Eugeniae

African Nightcrawlers
Eudrillus Eugeniae is native to the tropical west of Africa.

It is pink to purple. it can reach 200 mm.
However, it breeds slower than E. Fetida and E. Andrei.

It is found in equatorial areas. It can not stand the cold of temperate regions.
The optimal temperature for this species is between 23 ° and 30 ° C.

Lumbricus Rubellus

Red Earthworm
Lumbricus Rubellus is native to Northern Europe.

They are “reddish-brown” or “purple-red”.
It measures up to 105 mm. It breeds rather slowly.
It adapts easily to conditions of high acidity (pH between 3 and 7.7) and also supports colder temperatures.

Perionyx Excavatus

Blue Worm
Perionyx Excavatus comes from tropical climates.

It has blue to purple reflections (hence its common name).
It measures at adulthood about 100 mm and is rather thin. It breeds very fast, consumes waste quickly.

They prefer warm weather conditions (20 ° – 35 ° C).

On the other hand, it is sensitive to the changes of conditions of its environment (humidity, acidity, …) and will have a tendency to fugue …
