We received an interesting question from a reader through the All About Worms Facebook page about a “greenish grey worm” that his cat found on his lawn. The worm (or probably larva) is “2-3 inches long and had rings around it so he looked like a bunch of inter-tubes stacked on each other.” However, the defining characteristic of the creature is that it made noise. The reader was wondering what kind of worm or larva he (or technically his cat) found.
