This was a noticeably stripy worm. The compost worm has dark red bands alternating with pale pink or yellowish bands. There are two types of stripy earthworm. The Brandling Worm (Eisenia fetida) is also striped but has a red-brown saddle, the same as the main body colour, and is shorter and slimmer. This one has a paler saddle and is around 7cm long. The one below may have been a Brandling Worm, but I couldn’t see the saddle and it was still quite long, so perhaps not. Anyway, the picture below shows off the stripes much better. I spotted these worms in the rich compost sandwiched between old logs, which is exactly the sort of place they love to live in.
