Last month, we received a question about a worm from a reader in the UK (Plymouth, more precisely). She had found an orange worm (or what is perhaps an orange worm – it might not be a worm at all) in her garden. She found the worm late at night, and since she had never seen an orange worm before, she was curious to know what she had found. What is this orange worm, if it’s a worm at all?
