Reader Peter Thompson recently discovered this worm – and odd yellow blobs – in damp soil under a barrel on his property in Thetford, Vermont. What type of worm is this? And what are the clusters of tiny yellow spheres?
Answer
These are invasive jumping worms, which are extremely difficult to eradicate. They deplete the soil of nutrients and leave behind excreted castings that resemble coffee grounds, visible along the top of the photo. (Learn more about jumping worms on this page from the Vermont Agency of Agriculture Foods and Markets.) The yellow blobs are slug or snail eggs – it’s hard to know which until they hatch! Here’s a great post from naturalist Mary Holland on the topic.
