Worm Identification Pt 3-African Nightcrawlers

image4 A tropical species originating in savannah soils, Eudrius euginae  thrives on organically rich substrates.

It has a rapid life-cycle from cocoon to maturity in as little as 47 days.

Body length: up to 10-16 inches (25–40 cm) under optimal culture conditions but commonly mature at 4-6 inches (10-15 cm).

Each adult attains an average mass of about 0.04 Oz (1.0 g) or 0.18 to 0.21 Oz  (5.0–6.0 g) maximum.

Total segments: 161–211 (suggesting that larger worms add segments); Colour: Red-brown with bright blue/green iridescent sheen.

Clitellum begins at segment 13 or 14,  usually 13, animage1d covers 14–18 with a flat area of no clitellum on the underside.

The info here is only very basic to help identify whether you have gotten the correct worms in your order. For more detailed and scientific taxonomical info http://www.bioone.org/doi/pdf/10.5733/afin.056.0302

 

 

 

 

 

 

 

Advantages of using Eudrilus euginae:

  • Produce a fine pelleted casting with a pleasing appearance
  • Very fast to convert waste to casting/vermicompost
  • Large worm that can double as bait
  • Fast reproduction rate
  • Blue colour seems attractive to fish
  • Does well fishing in saltwater

Some disadvantages of Eudrilus euginae:

  • Quickly begin to die in temperatures below 60 F (16 C)
  • Soft skinned and fall off a fishing hook easily
  • Deposit casting on top of bin- this combined with fine pellet casting may make them unsuitable for a Continuous flow through system.
