“In addition to, thankfully, lots of earthworms, I often find small worm-like creatures in my (UK) home-made compost (see picture, which I will hopefully be able to attach)”, writes John in his submission regarding the tiny, cream-white and brown, worm-like creatures pictured below. “These are about three quarters to one inch long. What are they, and will they harm plants? Many thanks if you’re able to reply.” Upon zooming in on these critters, we can see that their bodies are segmented and that tiny antennae sprout from their heads. This fact, coupled with the shape of their bodies and the location in which they were found tells us that John has found millipedes.
